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.

Copper Removal from Industrial Wastewater Relies On Precision S80-T80 Analyzer

Ideal for Metal Processes, Electroplating, Wiring Production, Electronic Devices & More

Anaheim, CA—October 24, 2018—Process engineers responsible for the removal of copper from industrial wastewater to meet environmental, health and safety regulations will find the S80-T80 Copper Analyzer from Electro-Chemical Devices (ECD) provides a dependable and low-cost solution for accurate measurement in wastewater treatment systems.

ECD’s advanced S80-T80 Copper Analyzer relies on its highly accurate S80 Cupric ion electrode sensor, which is a combination electrode with a copper sulfide (CuS) solid-state pressed crystal sensing element and a double junction reference electrode housed in a rugged Radel body.  The universal S80 Cupric sensor connects with ECD’s intelligent T80 Transmitter, featuring dual channel mix and match capabilities for the measurement of multiple parameters, such as Cu and pH or many other parameters.

Copper (Cu) is used in industrial processes and in the manufacture of many different types of products, including electrical wiring, electronic components and devices, metals plating and processing, motors, sensors and more.  There are several processes available to remove heavy metals such as Cu from wastewater, which involve technologies such as adsorption, anaerobic treatment, membrane filtration, cementation and electro-dialysis.

All of the copper abatement processes have one thing in common—they require the accurate measurement of Cu before effluent discharge into the water system. The treatment of Cu in wastewater is complicated by the fact that Cu is both necessary to the normal functioning of the human body at the right levels and also is toxic to the body at higher than normal levels.      For this reason, the U.S. Environmental Protection Agency (EPA) has set a Cu maximum contaminant level (MCL) of 1.3 mg/L. The symptoms of over-exposure to Cu in water can include severe nausea, vomiting, gastrointestinal issues, muscle pain, anemia, liver or kidney failure and even death.

ECD’s versatile S80 pH Sensors come in immersion or insertion package configurations that are designed with a 0.75-inch MNPT compression fitting as the process connection. This design employs a variable insertion length to accommodate installation in pipe tees, flow cells or through tank walls. The 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 highly intelligent T80 Transmitter is available with single or dual channels designed for the continuous measurement of pIONs such as copper, or pH, ORP, dissolved oxygen, turbidity, conductivity or resistivity. The transmitter digitally communicates with any ECD universal S80 Sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter. Highly reliable, the transmitter features a built-in signal conditioner for noise-free transmission of data to the plant’s control system.

The T80 Transmitter features a large (2.75-x-1.5 inch) easily viewable 128-x-64 pixel LCD display with three easily switchable main display screens for data, millivolt and graphics. The display comes with a gray background and black lettering for loop powered instruments or with a blue background and white lettering with LED backlighting on 24 Vdc powered instruments.
