PCNE Featured TR80 Turbidity Analyzer

Intelligent Optical Sensor For Precise Turbidity Measurement

The new, versatile Triton TR80 Turbidity Analyzer from Electro-Chemical Devices features a highly effective nephelometric turbidity sensor designed for use in water and wastewater. Turbidity, the cloudiness or haziness of a water sample, is caused by particles or solids suspended in the water, typically clay and silt, or fecal matter, or various industrial wastes. As bacteria and viruses can be attached to these particles and solids, turbidity analysis has become a critical indicator of overall water quality.

 

RELIABLE LED LIGHTING

The advanced analyzer relies on the proven optical method with digital communications for determining turbidity and/or suspended solids. A light beam provided by the LED is directed into the sample where it is scattered by the particles or suspended particles in the water. The amount of scattering depends on the amount of impure material in the water, the wavelength of the light used and the size and composition of the particles or suspended solids. Employing a long-life near infrared LED light source and the 90-degree scattered light method of detection in accordance with ISO 7027/EN 27027, assures users of highly accurate turbidity measurement values under standardized and comparable conditions. The 90-degree scattered light detection method is the industry’s most common sensor design for turbidity. ECD’s powerful sensor design is advantageous in that it provides high sensitivity for turbid conditions over the entire measurement sample range.

PRE-CALIBRATED AND CUSTOM RANGES AVAILABLE

The versatile TR80 Sensor can be configured for both turbidity and/or Suspended Solids and connects via digital communications with the ECD T80 Transmitter or the ECD LQ800 Multi-Channel Controller for plug-n-play operation. Multiple standard factory pre-calibrated sensor ranges, as well as custom ranges upon request, are available including: 1 senor at 0.00-1000 mg/l or 0-1000 NTU, FNU; 3 sensors at 0.00-5000 or greater mg/l or 0-4000 NTU, FNU, ppm, mg/L; and 4 sensors at 0.00-30 mg/l or 0-30 NTU, FNU.
For ease of use and low life-cycle maintenance costs, The TR80 Turbidity Analyzer includes a simple optical configuration with an automated cleaning wiper to prevent the build-up of algae, oils and other contaminants. The wiper is pre-set at the factory to clean the sensor lens at regular intervals frequent enough to assure accurate measurement and reduce the need for technician manual inspection and cleaning, which over this instrument’s long life can add up to a significant operational cost savings.

The rugged TR80 Analyzer is available in four configurations: flow-through-cell, de-bubbler flow cell, immersion assembly and valve-retractable unit. Three choices of standard six-wire electrical connections are available with cable assemblies of either 10-ft (3.0 m), 20-ft (6.1 m) or 30-ft (9.1 m). It is designed for freezing to frying conditions operating from 23 to 122°F (5 to 50°C).

IPP&T Features TOC analyzer

ECD TOC analyzer monitors glycol at industrial plants

Those responsible for managing wastewater run-off treatment from commercial or private airports, aerospace industry facilities, military bases and chemical processing plants will want to learn more about how the advanced Total Organic Carbon (TOC) Analyzer from Electro-Chemical Devices (ECD) helps them manage ethylene glycol and other waste streams to safeguard water resources.

While primarily used for industrial process and manufacturing applications, ethylene glycol is key component in de-icing solutions for aircraft and airport runways during cold winter months. It is also found in automotive anti-freeze, coolant and brake fluids.

With its non-dispersive infrared (NDIR) detection technology, ECD’s TOC Analyzer helps pollution control engineers know that their wastewater treatment job is complete and that treated water effluent is ready for re-use or release.  Installing this analyzer helps facilities meet regulatory compliance requirements for treated facility storm or plant water with high confidence.

TOC analyzers measure the carbon in the organic matter that is nearly always present in water, whether it is surface water, ground water or treated industrial wastewater. Measuring TOC levels can be an important process variable when monitoring and controlling organic matter in water with residual glycol and other hydrocarbon pollutants.

There are many Industries and applications for ECD’s TOC Analyzer.  They include drinking water, feed and cooling water in manufacturing, facility runoff water and wastewater being discharged to the environment where an accurate and reliable TOC measurement is required to protect the water supply.

ECD’s TOC Analyzer is a full-featured instrument that utilizes the UV persulfate oxidation sensing method, which detects generated carbon dioxide (CO2) using its highly stable NDIR detector for analysis.   This method and the analyzer conform to: US EPA, DIN, CE, ASTM and NAMUR regulations, as well as ISO.

ECD’s TOC Analyzer is simple to use: the water sample is first acidified and then sparged to remove inorganic carbon.  The remaining liquid is mixed with sodium persulfate and digested by two high-performance reactors.  The resulting CO2 is then stripped from the liquid and, after drying, its concentration is measured by the NDIR analyzer. The analyzer measures TOC’s ranging from 0-5 mg/L to 20,000 mg/L, indicating the presence of glycol.

The advanced design of ECD’s TOC Analyzer features a valve-free sample line, which largely eliminates blockages. The analyzer’s auto clean, auto-calibration and auto-validation functions guarantee correct, reliable values that can be reproduced at any time without the need for manual intervention.

In comparison to conventional analyzers where the flow is controlled by a glass tube rotameter, the carrier gas flow with the ECD TOC Analyzer is controlled digitally. The flow is monitored via built-in smart diagnostics and if an abnormal value is detected, the analyzer stops automatically and displays a warning alert.

The rugged ECD TOC Analyzer is housed in a dual compartment enclosure.  The water sample components are in one compartment, and the electronics are located in a second compartment for safety and highly reliable operation.  The analyzer compartment is rated IP54, NEMA 3, and conforms to EN610004-2, EN610004-4, C46-022, EN 55022 and EN 61326.

The highly intuitive TOC Analyzer features a user touchscreen display located on the front of the analyzer.  All output/input data, status information, alarms and fault conditions are shown on the display.  Simply pressing the touchscreen buttons provides access to commands and settings.  The system is password protected for security.

TOCs in wastewater are regulated by the US EPA, state and local water quality standards. Many other industries rely on TOC measurement for analysis of wastewater prior to discharge. In addition, the power generation industries rely on TOC measurements for water quality concerning cooling water, condensate and boiler feed water.

Analyzer Plays Important Role in Mine Wastewater Cyanide Treatment

By Josue Nduwa, Development Metallurgist, Oceana Gold, Haile Operation, and Anil Isaac, Applications Engineer, Electro-Chemical Devices, Inc. 

Cyanide (CN) is commonly utilized in multiple industrial processes in the global mining, metals, chemical, electronics, steel, pharmaceutical and other industries. Five processes have been said to account for most of the CN wastewater streams, and they include: refining of gold and other metal ores, metal plating, case hardening of steel, neutralizing of process acid “pickle scum” and scrubbing of stack gases from blast and process industry gas furnaces. 

Well-known for its toxic properties, CN is a carefully regulated substance by environmental, health and safety agencies around the globe to protect workers, surrounding communities and local water supplies. When used in the gold mining industry in the form of Sodium Cyanide (NaCN) or Calcium Cyanide (CaCN2), the CN compound of choice is mixed with water in a carefully controlled process. Prior to extraction, the ore is first crushed and treated with the CN solution, which then becomes a flowing slurry during the gold extraction process. 

After gold extraction, the residual slurry ore wastewater solution is then transferred and stored for treatment by a mine operator to dissipate the high levels of CN. Due to its toxicity, the wastewater must be treated and evaluated to ensure that the CN level has been reduced to a safe level before discharge as effluent into the water system to prevent water supply contamination that could endanger people or wildlife. The human exposure limits for CN vary by the type and form of CN compound. According to the United States National Institute of Occupational, Safety & Health (NIOSH), the recommended exposure limit (REL) for NaCN is 5mg/m3 (4.7 ppm) over 10 minutes. Toxic exposure symptoms can include eye or skin irritation, asphyxia, lassitude, headache, vomiting, breathing difficulty and death. 

For these reasons the global mining industry takes CN process safety and environmental stewardship seriously. Industry CN process safety and environmental protocols are rigidly adhered to by mine management and employees. These protocols include required equipment operation and maintenance procedures. 

The Challenge 

Global mining company OceanaGold’s Haile Mine operation, which is located in the U.S. state of South Carolina, contacted the applications team at Electro-Chemical Devices (ECD) in Anaheim, California, to discuss its CN wastewater treatment process. The CN analyzers supporting the mine’s wastewater treatment process were requiring unusually high levels of maintenance, which also left open the possibility of inaccurate measurement, which is unacceptable. Gold was discovered in 1827 by Benjamin Haile in South Carolina and his Haile Mine has been in production on and off for nearly 200 years. In fact in the late 19th century, the Haile Mine was the most productive and profitable gold mine east of the Mississippi River. Today, the OceanaGold employees at the Haile Mine are proud of their company history and are deeply committed to safety and the protection of the environment. 

According to the U.S. Environmental Protection Agency (EPA), the best available technologies for CN wastewater remediation treatment are: oxidation by chlorine, ion exchange and reverse osmosis. The EPA has established a maximum contaminant level (MCL) of 0.2 mg/L and a maximum contaminant level goal (MCLG) of 0.2 mg/L as free cyanide prior to plant discharge of wastewater. In addition, CN wastewater streams are mobile in soils and have low adsorption to soils with high pH, high carbonate and low clay content. Untreated or ineffectively treated CN wastewater streams can leach to groundwater. Under typical conditions in natural waters (pH less than 9.2), most free cyanide is expected to convert to hydrogen cyanide that is highly volatile. The operations team at the Haile Mine relies on a three-step oxidation process to treat its CN wastewater. CN analyzers are placed at the starting point of the treatment process to measure CN levels entering the primary process, at the secondary treatment process to measure treatment effectiveness, and they are placed at the end-point of the process to ensure treatment has been completed to required effluent levels and meets regulatory requirements prior to discharge. 

Should the analyzer report CN levels above the legal limit, the water is returned to the system for additional treatment. Failure to meet the U.S. OSHA and U.S. EPA regulations for the safe use and treatment of CN can result in complex investigations, required actions and fines. 

The Solution 

The Haile Mine operations team was looking for a highly reliable and accurate CN analyzer solution, which also required a less frequent maintenance schedule. After reviewing the mine team’s operational requirements, the applications engineers at ECD recommended the company’s S80-T80 CN Analyzer System for a number of reasons. 

The company’s CN Analyzer Monitoring System is designed with an advanced, precision Pion CN sensor and a smart dual-channel universal transmitter. The Haile Mine plant operations team felt confident that the combination of the highly accurate Pion CN sensor with an intelligent dual-channel transmitter would help them achieve a more cost-effective CN treatment system with reduced maintenance at a lower analyzer lifecycle costs. 

The Pion CN electrode is a combination electrode with a silver cyanide/silver sulfide (AgCN/AgS) solid-state pressed crystal sensing element and a double junction reference electrode. The CN ion selective electrode cartridge develops a millivolt potential proportional to the concentration of free CN ions in the measured solution. The typical output is 54mV to 60mV per decade of change in concentration. The speed of the Pion CN sensor’s response varies from a few seconds in concentrated solutions up to a few minutes in the lower ppm ranges. The CN Pion sensors are used with the dual-channel transmitter, which allows mix and match capabilities that could include the measurement of pH, ORP or other parameters for example. This analyzer measures CN from 0.2 ppm to 260 ppm and auto-ranges the display between the ppb and ppm scales. 

The CN Pion sensors can be inserted into either immersion or insertion type packages that are designed with a 0.75-inch MNPT compression fitting as the process connection. The Haile Mine plant operations team appreciated the flexibility of this design, which also employs a variable insertion length to accommodate installation in pipe tees, flow cells or through tank walls. The sensor’s retractable configuration is designed with a 1-inch MNPT ball valve, a 1-x-0.75 inch reducer and a 0.75 inch MNPT compression fitting to provide the process connection. 

The smart universal transmitter is designed for the continuous measurement of multiple parameters in a general-purpose industrial environment. It communicates with multiple pre- calibrated sensors that measure various parameters and automatically configures the transmitter’s menus and display screens to the measured parameter. With the transmitter’s auto configuration capability to any of the available sensor measurements, the mine operations team no longer needed to maintain an inventory multiple instrument types, saving time and reducing plant operating costs. Technicians at the mine required no special training with the transmitter’s membrane switch navigation. A simple menu structure with soft key menu choices and an easy-to-read 2.75- x-1.5-inch LCD display made the set-up easy. The mine team also like the flexibility of transmitters 4-20 mA output with MODBUS RTU on 24 VDC and 110/220 VAC instruments. The transmitter also can be configured with HART® 7 communications and a three-alarm relay. 

Conclusions 

The new CN analyzers were installed and operational in less than 30-minutes each with no special technician training or tools. They have been operational now for over __ (years or months) with no issues reported. The mine operations team has recommended the CN analyzer system for use at additional company mines worldwide.

Water And Wastes Digest Features Electro-Chemical Devices

INSTRUMENTAL KNOWLEDGE

This article originally appeared in Water & Wastes Digest February 2020 issue as “Instrumental Knowledge”

The accurate process measurement of free chlorine, total chlorine and chlorine dioxide is essential to the successful operation of municipal and industrial water treatment systems that rely on this chemical for water disinfectant purposes, bleaching, corrosion prevention and other functions. Chlorine helps eliminate algae, bacteria, viruses, scale and other contamination in the treatment of both municipal drinking water and wastewater.

One of the most important things that all municipal and industrial systems have in common is their reliance on liquid analyzers to assure the maintenance of proper chlorine levels. Accurate, reliable analytical process measurement ensures public safety, protects plant equipment, increases quality, reduces maintenance, extends plant equipment life and lowers total costs.

Municipal Water & Wastewater

The majority of U.S. municipal water treatment systems disinfect their water using some type of chlorine-based process, either alone or in combination with other disinfectants.

Common pathogens including E. coli are controlled with chlorination, but failing to monitor or consistently maintain chlorine levels can result in less than appropriate disinfection levels and lead to disease outbreaks with devastating public health consequences.

Industrial Processes & Plants
Chlorine is also a common industrial bleaching agent in paper production and disinfectant in food and beverage plants, as well as providing oxidation control in chemical processing and other industrial operations including pharmaceuticals and textiles. The measurement of chlorine is important both in assuring the quality of water for cooling towers at petrochemical refineries and electric power generation plants to remove microorganisms, algae and biofilm in cooling water.

What is Free Chlorine?
Chlorine gas and/or sodium hypochlorite (bleach) are the common sources of chlorine in water. Both types form the same compounds when introduced to water: hypochlorous acid, HOCl, and hypochlorite, CIO—. The percentage of each component in solution is dictated by the pH of the solution. At roughly a pH level of 7.5, the ratio is 1:1. If the pH drops to 6.5, then the acid form is favored with 90% HOCl and 10% CIO—. At a pH level of 8.5, the alkaline form predominates as 90% CIO— and 10% HOCl.

Hypochlorous acid has roughly 10 times the oxidizing power of hypochlorite. These two types of chlorine are referred to as free chlorine. Other chlorine compounds may be present in the treated water as well, with organically bound chlorine and chloramine being the most common. These compounds are referred to as combined chlorine.

What is Total Chlorine?
Total chlorine is the sum of free chlorine and combined chlorine. The “combined chlorine” is typically referred to as what is “used-up” or “left-over” after disinfection. This residual amount is what is usually attributed as the cause for that bad smell in poorly treated pool water, which also can result in red eyes and burning skin. High total chlorine levels are an indicator that the water treatment disinfection system needs more free chlorine to do its job.

What is Chlorine Dioxide?
Chlorine dioxide (ClO2) is a chemical compound consisting of one chlorine atom and two oxygen atoms. It is a gas at room temperature that dissolves in water. It is used for a variety of antimicrobial uses, including drinking water disinfection, bleaching of paper and foods, corrosion control and sterilization. The U.S. EPA regulates the maximum concentration of chlorine dioxide in drinking water to be no greater than 0.8 parts per million (ppm).

Why & How is Chlorine Measured?
Chlorine is used primarily as a disinfectant or oxidizer or sanitizer; and, for best results, the levels must be monitored online, typically with a chlorine sensor. The chlorine is consumed as it disinfects, which is referred to as chlorine demand. To maintain the disinfection, a residual is needed. As such, the dose minus the demand equals the residual.

Free residual chlorine must be measured and controlled because it is an important aspect of keeping maintenance costs in line. The key to successful use of chlorine is in maintaining the right concentration. A chlorine concentration that is too high injects unnecessary costs into a process. Overly low levels of chlorine mean the process is not accomplishing the disinfection or other process goal and the process is ineffective.

Feedback in real time is critical with regard to how closely a process is maintaining the optimum levels of chlorination that are required. Concentration control of free chlorine at optimum levels means effective dosing occurs with no spikes or valleys that result when manual testing is performed. Additional benefits of online chlorine monitoring include:

  • Lower chlorine usage. It is an expensive chemical to source given the amount of energy required to produce chlorine;
  • Reduced maintenance needs by ensuring the process adheres to best practices; and
  • Good environmental stewardship.
    Process and plant engineers need free chlorine analyzer systems that measure precisely and are cost effective to install and maintain. The two major types of instruments for the measurement of free chlorine are colorimetric tests and amperometric analyzers.

There are two types of colorimetric tests. The manual test method is similar to a swimming pool test. The automated colorimetric test requires a sample system and reagents. Colorimetric tests are EPA approved for reporting purposes, but they are not real time measurements that are the best suited for accurate process control.

Amperometric analyzers feature a rugged chlorine sensor that is automatically compensated for pH. There are also multiple manufacturers of amperometric analyzers with many different models, as well.

New ECD TOC Analyzer Monitors Glycol At Airports and Industrial Plants

NDR Technology Enhances Measurement Accuracy and Reliability

 

Anaheim, CA—February 25, 2020—Those responsible for managing wastewater run-off treatment from commercial or private airports, aerospace industry facilities, military bases and chemical processing plants will want to learn more about how the advanced Total Organic Carbon (TOC) Analyzer from Electro-Chemical Devices (ECD) helps them manage ethylene glycol and other waste streams to safeguard water resources.

While primarily used for industrial process and manufacturing applications, ethylene glycol is key component in de-icing solutions for aircraft and airport runways during cold winter months. It is also found in automotive anti-freeze, coolant and brake fluids.

With its non-dispersive infrared (NDIR) detection technology, ECD’s TOC Analyzer helps pollution control engineers know that their wastewater treatment job is complete and that treated water effluent is ready for re-use or release.  Installing this analyzer helps facilities meet regulatory compliance requirements for treated facility storm or plant water with high confidence.

TOC analyzers measure the carbon in the organic matter that is nearly always present in water, whether it is surface water, ground water or treated industrial wastewater. Measuring TOC levels can be an important process variable when monitoring and controlling organic matter in water with residual glycol and other hydrocarbon pollutants.

There are many Industries and applications for ECD’s TOC Analyzer.  They include drinking water, feed and cooling water in manufacturing, facility runoff water and wastewater being discharged to the environment where an accurate and reliable TOC measurement is required to protect the water supply.

ECD’s TOC Analyzer is a full-featured instrument that utilizes the UV persulfate oxidation sensing method, which detects generated carbon dioxide (CO2) using its highly stable NDIR detector for analysis.   This method and the analyzer conform to: US EPA, DIN, CE, ASTM and NAMUR regulations, as well as ISO.

ECD’s TOC Analyzer is simple to use: the water sample is first acidified and then sparged to remove inorganic carbon.  The remaining liquid is mixed with sodium persulfate and digested by two high-performance reactors.  The resulting CO2 is then stripped from the liquid and, after drying, its concentration is measured by the NDIR analyzer. The analyzer measures TOC’s ranging from 0-5 mg/L to 20,000 mg/L, indicating the presence of glycol.

The advanced design of ECD’s TOC Analyzer features a valve-free sample line, which largely eliminates blockages. The analyzer’s auto clean, auto-calibration and auto-validation functions guarantee correct, reliable values that can be reproduced at any time without the need for manual intervention.

In comparison to conventional analyzers where the flow is controlled by a glass tube rotameter, the carrier gas flow with the ECD TOC Analyzer is controlled digitally. The flow is monitored via built-in smart diagnostics and if an abnormal value is detected, the analyzer stops automatically and displays a warning alert.

The rugged ECD TOC Analyzer is housed in a dual compartment enclosure.  The water sample components are in one compartment, and the electronics are located in a second compartment for safety and highly reliable operation.  The analyzer compartment is rated IP54, NEMA 3, and conforms to EN610004-2, EN610004-4, C46-022, EN 55022 and EN 61326.

The highly intuitive TOC Analyzer features a user touchscreen display located on the front of the analyzer.  All output/input data, status information, alarms and fault conditions are shown on the display.  Simply pressing the touchscreen buttons provides access to commands and settings.  The system is password protected for security.

TOCs in wastewater are regulated by the US EPA, state and local water quality standards. Many other industries rely on TOC measurement for analysis of wastewater prior to discharge. In addition, the power generation industries rely on TOC measurements for water quality concerning cooling water, condensate and boiler feed water.

Versatile Analyzer Supports Municipal and Industrial Water & Effluent Treatment

Anaheim, CA—October 22, 2019—With its all-in-one design, the versatile CA900 Analyzer from  Electro-Chemical Devices (ECD) delivers continuous,  accurate measurement of fluoride in aqueous solutions to support a wide range of municipal water and industrial plant process and effluent treatment applications.

The dependable CA900 Fluoride Analyzer’s unique all-in-one design eliminates the need for additional water sample pretreatment equipment, reducing installation complexity, maintenance tasks and lifecycle costs. This advanced design is based on ECD’s rugged industrial grade ion selective electrode measurement technology.

Fluoride (F) is derived from common fluorine, which is naturally and widely found in the earth’s crust.  Low concentrations of fluoride also occur in sea water, rivers and rain.  It is well known as a municipal drinking water additive to promote dental health, as well as in tooth pastes, mouth washes and some medicines.  This useful chemical also has a variety of industrial uses including hydrofluoric acid, semiconductor etching, glass frosting and in the production of specialty materials such as Teflon, textiles and insecticides.

The CA900 Fluoride Analyzer’s mixing chamber contains fluoride ion electrodes and pH electrodes for measurement purposes. It features automated titration technology. A TISAB reagent is flowed to provide an ionic strength adjustment to the liquid sample, breaking down weak complexes formed with fluoride and other metals, such as aluminum or iron, prior to the actual fluoride concentration measurement.  A pH compensation technique is employed along with special algorithms to provide accurate fluoride measurement across multiple pH ranges.

With its rugged construction, the CA900 Fluoride Analyzer operates in challenging environments from 0 to 50°C (32 to 120°F).  It offers a wide measurement range from 0.1 to 200 mg/l (0.1 to 200 ppm).  Highly dependable, it features accuracy of ±100 ppb, or 5% of measurement, or whichever is greater and repeatability of ±2% for consistent measurement.

Featuring auto calibration, the CA900 Fluoride Analyzer offers users a choice of two pre-set levels to choose from–either 1 ppm or 10 ppm on its touch screen display.  The touch screen display and 4-20 mA outputs then indicate total fluoride and the pH value.

The CA900 Fluoride Analyzer is housed in two separate moisture resistant NEMA 4X, IP65 type enclosures with lockable doors for security.  The top compartment houses the electronics safely away from the liquids, including the main power supply, the controller PCB assembly and an easy-to-read graphical touch screen display.  The lower compartment includes all the liquid components involved in collecting the sample and flowing the reagent, mixing the solution and then final measurement.

The CA900 Fluoride Analyzers are easy to start up and use. Simply connect the sample, waste and reagent lines, and then power up the factory calibrated analyzer. Wall mounting hardware is standard but an optional benchtop stand with reagent holder is also available.

Accessing information or customizing an analysis routine are accomplished with the display’s simple, user friendly menu structure and touch screen interface. The analyzer features full data logging and is web enabled for remote monitoring and interfacing with personal handheld devices and computers.

The CA900 Fluoride Analyzers can be powered either as 100/230 VAC or 50/60Hz via its selector switch.  It includes four 4 to 20 mA outputs, four configurable SPDT relays and serial output.  The unit’s four SPDT relays can be set from 15A to 250VAC

In addition to the CA900 Analyzer, ECD also offers its direct insertion S80 Ion Fluoride Sensor and T80 Transmitter. The identity of the sensor, measurement type and serial number are stored in the sensor’s digital memory along with three calibration registers.   When the S80 Fluoride Sensor is connected to the T80 Transmitter, it becomes a powerful liquid analyzer. It measures free fluoride ions from 0.02 to 2,000 ppm in the optimum range level of 5-8 pH.

ECD Family of HYDRA-DS Analyzers Simplify Nitrogen (Nutrients) and Ammonium Measurement

Accurate Monitoring of Wastewater Treatment Effluent and Surface Water Storage

Anaheim, CA—September 26, 2019—Developed with advanced ion selective electrode (ISE) sensor technology and a highly intelligent transmitter, the family of HYDRA-DS Analyzers from Electro-Chemical Devices (ECD) simplifies the accurate measurement of harmful nitrogen (nutrients) and ammonium to maintain water quality in a wide range of environments.

HYDRA-DS Nitrate Analyzers

The HYDRA-DS Nitrate Analyzers are designed to monitor the nitrification process directly in a wastewater treatment plant’s aeration basin or clarifier unit. Its advanced sensor uses ISE technology to measure the Nitrate. Also featuring a self-compensating design, the HYDRA DS automatically eliminates Chloride ion interference for high accuracy and reliability.

The HYDRA-DS Nitrate Analyzers measure the concentration of dissolved nitrate as nitrogen (NO3-N) in water. The sensor uses two electrodes to determine the NO3-N concentration, a nitrate ion electrode and a chloride ion electrode. It is designed for use in all kinds of water ranging from municipal and industrial wastewater treatment.

For example, nitrogen typically enters a municipal wastewater treatment plant as ammonia/ammonium compounds. Nitrification oxidizes the toxic ammonium ion into a much less toxic nitrate ion using an aerobic activated sludge process. De-nitrification reduces the nitrate ion (NO3) to nitrogen gas (N2) by an anoxic reaction in the same treatment basin or in a separate anaerobic digester. The NO3-N measurement can optimize the methanol being fed to the digester, minimizing cost, and also provides a trend of the total nitrogen in the effluent.

The nitrate ion electrode performs the primary measurement. A second electrode measures the chloride ions in the sample. The chloride ion, because of its similar size and charge to the nitrate ion, causes a positive interference in the measurement. The chloride ion electrode measures the amount of chloride ion present in the sample and the intelligent transmitter subtracts the appropriate amount of signal from the nitrate measurement.

The HYDRA-DS sensor rapidly measures NO3-N and NH4-N from 0.1 to 14,000 ppm with a response time of 1 minute (T90) and an accuracy of ±3% of reading, dependent on calibration.  It operates over a wide temperature range from 32 to 122°F (0 to 50°C).  Its highly intelligent transmitter includes an easy-to-read backlit display and comes with two 4-20mA outlets and three SPDT alarm relays.  An integral automated sensor spray cleaner reduces biofilms to enhance accuracy and reduce sensor maintenance.

HYDRA-DS Ammonium Analyzers

The HYDRA-DS Ammonium Analyzer is designed to monitor the nutrient load (NH4+) directly in the aeration basin of a wastewater treatment plant. Its powerful sensor uses ISE technology to measure the ammonium, potassium and pH levels. Its self-compensating design automatically compensates for the pH-dependent concentration equilibrium and potassium ion interference on the ammonium electrode.

The ammonium sensor measures the concentration of dissolved ammonium as nitrogen (NH4+-N) in water. The sensor uses three electrodes to determine the NH4+-N concentration, an ammonium ion electrode, a potassium ion electrode and a pH electrode. It is designed for use in all kinds of municipal wastewater or wherever ammonium is present in water.

The ammonium ion electrode performs the primary measurement. Any potassium ion in the sample, however, generates a positive interference in the measurement because of its similar size and charge to the ammonium ion.  The HYDRA-DS Analyzer’s highly intelligent transmitter self-compensates by adjusting the signal for this potassium interference and eliminates it from the measurement of ammonium for superior accuracy and reliability.

The ammonium ion electrode measures the ammonium ion (NH4+), not ammonia (NH3).  The ammonium ion and ammonia coexist in a pH dependent ratio in solution. The more acidic pH values favor the NH4+ and the more basic values favor dissolved ammonia gas, NH3. The pH electrode measures the pH level, and the transmitter calculates the total NH4+-N concentration based on the pH versus the NH4+ concentration profile stored in the instrument.

The HYDRA-DS Analyzer rapidly measures NH4+-N from 0.1 to 14,000 ppm with a response time of 1 minute (T90) and an accuracy of ±3% of reading, dependent on calibration. It also operates over a wide temperature range from 32 to 122°F (0 to 50°C).  Its intelligent transmitter also includes an easy-to-read backlit display and comes with two 4-20mA outlets and three SPDT alarm relays.  An integral automated sensor spray cleaner reduces biofilms to reduce sensor maintenance.

Cooling Tower Ozone Disinfection Systems Rely On Reagent-Less O3 Analyzer for Monitoring

Ideal for Rugged High Temperature Industrial Evaporative Cooling Processes: Chemical Plants, Electric Power, Oil/Gas Refining, Pulp/Paper and More

Irvine, CA—August 15, 2019—Plant engineers who’ve switched or who are thinking about the switch to Ozone (O3) disinfection of water for high-temperature evaporative cooling towers will find the reagent-less OZ80 Ozone Analyzer from Electro-Chemical Devices provides a green-friendly design that helps them optimize treatment while at the same time reducing cost, simplifying maintenance and avoiding complex environmental issues.

ECD’s advanced OZ80 Analyzer helps ensure effective ozone treatment of cooling tower water to prevent bacterial growth, scaling and corrosion.  Ozone as a disinfectant replaces the need for chlorine and other harsh biocides and inhibitor chemicals that are considered toxic hazards, require special wastewater treatment and effluent monitoring.

In comparison to reagent-type analyzers that come with multiple components which first must be installed and then require field calibration, the OZ80 Analyzer is factory assembled and factory calibrated prior to arrival.  All the technician needs to do is mount the panel and connect the drain lines, plug in the power cord and select the outputs on the display as 0 to 2.0 ppm for water disinfection or 0-20.00 pm for oxidation and bleaching operations.

Dual range measurement of both Ozone (O3) parameters also is available with the OZ80 Analyzer.  Ois a colorless to pale blue gas that in low concentrations gives off an irritating acidic odor.  It is a strong oxidizer, stronger than either chlorine (Cl) or chlorine dioxide (ClO2).  O3 reacts quickly and disintegrates into oxygen gas without the formation of harmful disinfection byproducts (DPB’s) common to chlorine disinfectants that require additional costly treatment.  It also increases the amount of oxygen in the water.

O3 is gaining ground as a disinfectant and bleaching agent in multiple industrial processes.  It has been used for years in municipal drinking water and wastewater treatment plants.  It is useful at several points in the drinking water treatment process as an oxidizer for removing metals from well water as well as organics, odors and color from surface water too.

ECD’s OZ80 Analyzer features powerful amperometric sensors to detect and monitor O3 levels. These amperometric sensors are manufactured with a gold cathode, a silver anode and a rugged microporous membrane. Unlike many other analyzers, there are no reagents required with the OZ80 Analyzer.  Its O3 sensor technology and pH measurement are reagent-less designs. These sensors keep the cost of ownership low by not requiring expensive reagents.

The O3 sensors are smart sensors with their identity and calibration information stored internally. Communication between the OZ80 Analyzer’s T80 Transmitter and the O3 sensor is via MODBUS. The sensors are flow sensitive requiring a minimum flow rate of 0.5 ft/sec, above this flow rate, the reading is virtually independent of the flow rate.

The OZ80 Analyzer’s constant head flow control device (CFD) maintains the optimum flow rate moving past the sensor for sampling purposes.  The CFD’s automatic flow control capability eliminates the need for pressure regulators and rotameters, which are required by many other H2O2 analyzers, to reduce system maintenance and lifecycle operating costs.  The minimum flow rate required by the CFD is 10 gal/hr, and the maximum flow rate is 80 gal/hr with the sample draining at atmospheric pressure.

The OZ80 Analyzer is available with an optional sensor auto clean configuration.  The sensor auto clean features a solenoid actuated spray cleaner that provides either a 30 psi process water or air.  The spray cleaner removes films from the sensor head, which over time can affect measurement accuracy.  There is rarely a need for manual wiping of the sensor head by maintenance technicians with the spray clean configuration.

Designed with ECD’s T80 Universal Transmitter, the OZ80 Analyzer includes a 128-x-64 pixel (2.75-x-1.5-inch) display.  The display is black on grey with no backlight or blue on a white background with the LED backlight.  The standard configuration features two 4-20 mA outputs, three alarm relays and MODBUS RTU.  The enclosure is rated to IP65 and weatherproof.

Self-Cleaning Ultra Violet Family of Water Analyzers Ready to Go Right Out of the Box with No Reagents

Ideal for Drinking Water Disinfection and Wastewater Treatment

Anaheim, CA—July 24, 2019—With their advanced ultra violet absorption sensing technology, the new family of UV-6 Analyzers from Electro-Chemical Devices (ECD) helps treatment plant engineers and technicians assure the safety of surface and ground water supplies, drinking water disinfection and protect the environment from untreated wastewater effluent.

Relying on their sophisticated UV absorption correlation technology, the ECD UV-6 Analyzers are designed to monitor five separate parameters over a wide range of values.  They accurately measure via their spectroscopic sensor at a 254 nm wavelength with correlation algorithms the presence of ammonia, nitrate chemical oxygen demand (COD), biological oxygen (BOD) or total organic carbon (TOC).

The analyses of these pollutants are based on the measurement of UV absorption in a collected sample. Ammonia measurement is available in two ranges: either 0 to 10 ppm or 0 to 1000 ppm. Nitrate measurement is available in three ranges: 0 to 30 mg/L, 0 to 100 mg/L or 0 to 250 mg/L.  Measurement of COD, BOD and TOC is available in two ranges:  0 to 200 mg/L or 0 to 20,000 mg/L

The absorbance of the solution or gas is measured though a quartz flow cell at a specific wavelength using a long-life Xenon light source and photo-detectors. The absorbance is related to the sample concentration according to the Beer-Lambert Law, which relates the attenuation of light to the properties of the solution through which a projected light is traveling.

The UV-6 Analyzers come pre-calibrated from the ECD factory, which makes them easy to install and start up.  There’s no complicated assembly or calibration solutions, no special tooling needed or lengthy technician installation training.  Simply remove the analyzer from the packaging, connect the sample, waste and cleaning lines, plug-in and power up the unit.  Wall mounting hardware is provided standard, and an optional benchtop stand is also available.

This family of easy-to-use analyzers greatly reduces technician maintenance time and consumables expenses.  The design of the UV-6 features a built-in spray cleaning system that keeps the light source and sensor cell free from algae growth and sticky particles to ensure accuracy.  Best of all there are no costly reagents required, which also must be disposed of properly to prevent environmental contamination.

Data logging is provided via RS232 communications.  Four alarm relays are included, which are normally open, 5 Amp at 250 VAC, along with a single 4-20 mA output with 12-bit resolution.  Choose from multiple power supply options: 110-130 VAC or 220-240 VAC /30VA / 50-60Hz, or 12-15 VDC /4A.

New ECD Total Organic Carbon (TOC) NDIR Analyzer Assures Municipal & Industrial Water Quality

Municipal & Industrial Wastewater, Drinking Water, Power Generation and More

Anaheim, CA—August 23, 2018— Engineers responsible for municipal drinking water or industrial process water, as well as wastewater effluent, will discover that the new next-gen precision Total Organic Carbon (TOC) Analyzer from ECD Analyzers with non-dispersive infrared (NDIR) detection technology helps them know with high confidence that their treatment job is complete and that treated water is ready for use or re-use.

Installing ECD’s TOC Analyzer helps plants reduce costs, increases operational efficiency and supports regulatory compliance.  Organic matter is nearly always present in water, whether it is surface water, raw or treated water. Measuring total organic carbon, or TOC, can be an important process variable when monitoring and controlling organic matter in water.

There are many Industries and applications for ECD’s TOC Analyzer.  They include drinking water, feed and cooling water in manufacturing, runoff water and wastewater being discharged to the environment where an accurate and reliable TOC measurement is required to protect the water supply.

ECD’s TOC Analyzer is a full-featured instrument that utilizes the UV persulfate oxidation method, which detects generated carbon dioxide (CO2) using its highly stable NDIR detector for analysis.   This method and the analyzer conform to: US EPA, DIN, CE, ASTM and NAMUR regulations, as well as ISO.

Using the ECD TOC Analyzer is simple: the water sample is first acidified and then sparged to remove inorganic carbon.  The remaining liquid is mixed with sodium persulfate and digested by two high-performance reactors.  The resulting CO2 is then stripped from the liquid and, after drying, its concentration is measured by the NDIR analyzer. The analyzer measures TOC’s ranging from 0-5 mg/L to 20,000 mg/L.

The analyzer’s advanced design features a valve-free sample line, which largely eliminates blockages. The analyzer’s auto clean, autocalibration and autovalidation functions guarantee correct, reliable values that can be reproduced at any time without the need for manual intervention.

Unlike conventional analyzers where the flow is controlled by a glass tube rotameter, the carrier gas flow with the ECD TOC Analyzer is controlled digitally. The flow is monitored via built-in smart diagnostics and if an abnormal value is detected, the analyzer stops automatically and displays a warning alert.

The ECD TOC Analyzer is housed in a dual compartment enclosure.  The water sample components are in one compartment, and the electronics are located in a second compartment for safety and highly reliable operation.  The analyzer compartment is rated IP54, NEMA 3, and conforms to EN610004-2, EN610004-4, C46-022, EN 55022 and EN 61326.

The ECD TOC Analyzer features an optional fast loop reservoir for safe operation in case of a sample loss.  It maintains a constant sample flow and switches the analyzer to standby in the case of insufficient flow (dry running).  As soon as the sample flow restarts, the measurement is process is resumed.

Highly intuitive and simple to use, the ECD TOC Analyzer’s user interface is a touchscreen display located on the front of the analyzer.  All output/input data, status information, alarms and fault conditions are shown on the display.  Simply pressing the touchscreen buttons provides access to commands and settings.  The system is password protected for security.

Monitoring the TOC level of plant incoming source water will detect early pollution events and prompt action to be taken to divert or close the raw water intake before the treatment plant is contaminated. The monitoring of TOC content in finished water prior to distribution is also required in some countries to control disinfection by-products.

TOCs in municipal drinking water and wastewater are regulated by the US EPA, state and local water quality standards.  The same is true for industrial process wastewater effluent at plant discharge. Food/beverage, pharmaceutical and other industries rely on TOC measurement for analysis of wastewater prior to discharge. In addition, the power generation industries rely on TOC measurements for water quality concerning cooling water, condensate and boiler feed water.
