Anaheim, CA—January 25, 2022—Process and plant engineers requiring ultra-pure or high purity water for a wide range of ingredient and rinsing or washing or feed water applications ranging from pharmaceuticals to food/beverage to green hydrogen (H2) electric power will find the NA6 Sodium Analyzer from Electro Chemical Devices (ECD) sets the standard in providing accurate measurement, reliability and ease of use.

Many consumer products and industrial processes rely on ultra-pure or high-purity water. They include pharmaceutical water for injection (WIF), beer or other beverages and food products where water quality affects taste, as well as the sanitary rinsing of clean-in-place (CIP) equipment. Other industrial applications include H2 electrolysis production for green electric power, corrosion prevention in steam turbines for conventional electric power generation, steam boilers in refineries, as well as semiconductor fabrication, glass production and metal plating.

With an advanced glass electrode sensor that measures sodium in water to the parts per billion (ppb), parts per million (ppm) or milligram per liter (mg/l) levels, the ECD NA6 Sodium Analyzer is the flexible water quality assurance tool. The sodium sensor’s measurement range of 0.1 to 10 ppb is based on the proven accuracy of ECD’s sodium glass electrode sensor for the online potentiometric detection of low ppb traces of sodium.

When exposed to raw process or treated process water, ECD’s sodium glass electrode sensor produces an electronic signal potential proportional to the log of the sodium concentration. The sample is exposed to a reagent vapor, which raises the sample pH to 11 to eliminate any pH or ammonium interferences that would affect measurement accuracy. Highly reliable too, reproducibility is ±0.2 ppb or 5%, whichever is greater at constant temperature.

The NA6 Analyzer features a tri-compartment design for reliability and safety. The electronics and user interface display are in the top compartment, with the calibration solutions for autocal in the middle compartment and the wet sample housed in the bottom of the unit. The electronics are always dry and safe from moisture for superior reliability.

ECD T80-S80 DO Analyzer

Smart DO Analyzer Helps Water Technicians Protect Water Quality in Surface and Tank Storage Systems

 Preserving Aquatic Plants and Wildlife in Environmentally Sensitive Lakes, Streams, Ponds, Municipal Water Reservoir Storage, Fisheries & Hatcheries

Anaheim, CA—October 25, 2021—Water engineers, environmentalists and aquaculture technicians will find the S80-T80 Dissolved Oxygen Analyzer from Electro-Chemical Devices (ECD) helps them easily, accurately and economically measure dissolved oxygen (DO) levels to ensure they support sensitive ecosystems, as well as municipal water storage and fish farming.

Dissolved oxygen is the amount of oxygen that is naturally present in bodies of water. These water sources receive their oxygen from the atmosphere and from aquatic plants. Running water, such as that of a swift moving stream, dissolves more oxygen than the still water of a pond or lake. All aquatic animals such as fish need adequate levels of DO to breathe.

The easy-to-use, economical ECD S80-T80 DO Analyzer with its intelligent S80 sensors and intuitive T80 transmitter is the perfect solution for measurement.  This analyzer comes pre-calibrated from the factory, requiring no special tools or installation training.  It’s a plug-n-play system that’s ready-to-go out of the box and designed for busy water engineers and techs.

According to the U.S. Environmental Protection Agency (EPA), low levels of oxygen (hypoxia) or no oxygen levels (anoxia) can occur when excess organic materials, such as large algal blooms, are decomposed by microorganisms. During this decomposition process, DO in the water is consumed.  Knowing DO levels allows technicians to remediate issues early on.

Low oxygen levels often occur in the bottom of the water column and affect organisms that live in the sediments. In some water bodies, DO levels fluctuate periodically, seasonally and even as part of the natural daily ecology of the aquatic resource. As DO levels drop, some sensitive animals might move away, decline in health or even die.

To prevent these issues, environmentalists, municipal water engineers and industrial technicians often must monitor DO levels—especially in municipal surface water storage systems consisting of reservoirs, lakes, ponds and tanks or enclosure pens for aqua-culture or fish hatcheries.  Failure to maintain sufficient oxygen levels also can jeopardize municipal drinking water quality and jeopardize sensitive wildlife.

When the intelligent S80’s sensor is connected to the versatile T80 Transmitter, the sensor’s information is uploaded to the analyzer. It then configures the displays and outputs of the transmitter to the values appropriate to the DO sensor’s measurement parameters. The S80-T80 DO Analyzer measures dissolved oxygen levels from 0 to 20 ppm (mg/L) at 250 percent saturation. They operate over a pressure range of 0 to 50 psig and at temperatures (-5 to 80°C).

The standard S80 sensors have 316 Stainless Steel housings although various materials of construction are available to maximize sensor performance while minimizing cost of ownership. They are available in either a choice of insertion or valve retractable configurations for quick disconnect and replacement of sensor cartridges.

The universal T80 Transmitters are available as either single channel or dual channel instruments. This transmitter comes in a 24 VDC or a 100/240 VAC power configuration. All versions are available with the optional HART® output. These line powered instruments have one 4-20 mA output per channel and a MODBUS RTU. Other options include a three alarm relay package configurable as alarm (set point) relays, timer activated relays or fault relays.

Ideal Solution for Helping Meet Latest U.S. EPA LCR Requirements, as well as European Union’s RoHS Directive 2002/95/EC

Anaheim, CA—September 27, 2021—Plant engineers responsible for clean, safe drinking water in their communities and those engineers in business tasked with industrial wastewater treatment will find that the S80-T80 Lead (Pb) Analyzer and S80-T80 Copper (Cu) Analyzer from Electro-Chemical Devices (ECD) helps them verify treated water quality.

The U.S Environmental Protection Agency (EPA) Lead and Copper Rule (LCR), updated in late 2020, is now in place for municipalities with lead pipes. These Pb testing requirements will extend to schools and other public facilities as well to protect youth and families. The EPA has estimated there are 6 to 10 million aging municipal water lead service lines and systems that must be tested and upgraded to prevent future Pb contamination of the water supply.

The electronics industry also has recognized for decades that water and soil contamination by lead and copper have been a problem in the manufacture of semiconductors, passive components and circuit boards. The EPA issued in 1983 its Electrical and Electronic Components (E&EC) Effluent Guidelines and Standards (40 CFR Part 469) to address the issue. In addition, electronics companies worldwide must adhere to the Restriction of Hazardous Substances (RoHS) regulations per European Union (EU) Directive 2002/95/EC.

To assist municipal and industrial process and plant engineers, ECD has developed a modular family of ion selective Pb and Cu analyzers. A wide array of ECD water quality sensors are also available for other municipal water needs, including Ammonium, Calcium, Chlorine, Chromium VI, Fluoride, Nitrate, Nitrite, Phosphates and Sulfur. Industrial sensors and systems are available for Bromide, Cadmium, Cyanide, Manganese, Nickel, Potassium, Silver and more.

When the intelligent S80 Pb ion selective sensor is connected to the versatile T80 Transmitter, the sensor’s information is uploaded to the analyzer. It then configures the displays and outputs of the transmitter to the values appropriate to the Pb sensor’s measurement parameters. The S80-T80 Pb Analyzer measures Pb over a range of 2.0 to 20,700 ppm at a pH level of 4-8 over a wide temperature range from 32 to 176°F (0 to 80°C) with a T90 response time of 10 seconds.

For copper monitoring, the Cu S80 Sensor is connected to the same, modular T80 Transmitter, with the ion-selective Cu sensor’s information uploaded to the analyzer. It also then configures the displays and outputs of the transmitter to the values appropriate to the Cu sensor’s measurement parameters. The highly sensitive S80 Cu sensor operates over an exceptionally wide measurement range of 1.0 ppb to 6,300 pm at a pH level of 2-4 over a temperature range 32 to 176°F (0 to 80°C) with aT90 response time of 10 seconds.

The versatile design of the ion-selective S80 sensor family can be specified for insertion, immersion or valve retractable service. Their rugged design is suitable for heavy-duty municipal and industrial applications and includes a choice of materials: 316 Stainless Steel, Titanium or Hastelloy. Maintenance is simple with a replaceable electronic cartridge, which can be performed by plant technicians without any special tools or training.

The universal T80 Transmitters are available as either single channel or dual channel instruments, allowing one analyzer to measure both Pb and Cu. This transmitter is available in a 24 VDC or a 100/240 VAC power configuration. All versions are available with the optional HART® output. The line powered instruments have one 4-20 mA output per channel and a MODBUS RTU. Other options available include a three alarm relay package. The relays can be configured as alarm (set point) relays, timer activated relays or fault relays.

The Triton TR80 is a nephelometric turbidity sensor designed for use in water and wastewater. Turbidity, the cloudiness or haziness of a water sample, is caused by particles suspended in the water, typically clay and silt. Since bacteria and viruses can be attached to these particles, turbidity has become a critical indicator of the overall water quality.

The Triton TR80 uses an optical method for determining the turbidity suspended solids, a light beam is directed into the sample where it is scattered by suspended particles in the water. The amount of scattering depends on the amount of material in the water, the wavelength of light used and the size and composition of the suspended particles. The TR80 uses a long lived near infrared LED light source and the 90° scattered light method in accordance with ISO 7027 / EN 27027 to assure accurate turbidity values under standardized and comparable conditions. The 90° scattered light detection method is the most common sensor design for turbidity. This sensor has the advantage of a high sensitivity for turbidity throughout the measurement range and a simple optical configuration with an automated cleaning wiper.

The TR80 sensor can be configured for turbidity and/or Suspended Solids and connects with the ECD T80 Transmitter or the ECD LQ800 Multi-Channel Controller.

Enviro-Tech Online, Plug-n-Play De-Chlorination Analyzer, Jan. 5

Municipal water system and industrial process engineers in search of an analyser that accurately measures near zero levels of chlorine will want to learn more about the plug-n-play, long-life DC80 De-Chlorination Analyser from Electro-Chemical Devices (ECD), which utilises a zero-shift methodology to ensure stable and reliable chlorine measurement prior to effluent discharge.

When measuring near zero amounts of chlorine, conventional amperometric chlorine sensors are unstable, and this leads to inaccurate or inconsistent readings. In comparison, the DC80 De-Chlorination Analyser utilises a “zero-shift” methodology to provide accurate measurement and to protect total chlorine sensors from damage, which occurs when the water samples measured contains near zero or zero levels of chlorine.

In wastewater treatment systems, for example, when monitoring for chlorine just before outfall, there can be no chlorine present and yet measurement is still necessary. When there is no chlorine present then the electrode becomes unstable and finally unresponsive. For this reason, the process of measuring de-chlorination itself becomes problematic. When all of the chlorine is removed then the sensor will provide an inaccurate reading after a few hours and fail after a few days still reporting zero chlorine

Problem solved with the DC80 De-Chlorination Analyser: This next-gen total chlorine analyser uses “zero shifts” technology to monitor near zero amounts of total chlorine. Using this method, some chlorine is actually metered into the sample shifting the zero from a near zero chlorine concentration to a measurable value. The analyser’s offset feature allows the metered value to be subtracted from the measurement.

The presence of chlorine in wastewater treatment effluent, both municipal and industrial, is a potentially harmful contaminant that affects plants and other aquatic life forms.

The DC-80 De-Chlorination Analyser monitors chlorine in drinking water, wastewater, cooling water and other de-chlorination applications from 0.05 – 20 ppm. Its mounted system includes built-in flow control, which eliminates the need for complicated plug-and-play design installs quickly right out of the box.

The DC80 features advanced panel pressure regulators and rotameters. Built-in automatic pH compensation for samples between 4 and 12 pH also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.

The analyser’s total chlorine sensor is a three electrode amperometric sensor with a gold cathode, silver halide anode and 304 stainless steel counter electrode. The counter electrode provides a stable base potential that minimises drift for superior accuracy. The total chlorine sensor has a micro-porous membrane that allows ions to diffuse in and out of the sensor.

The analyser’s pH sensor provides accurate compensation for samples between 4 and 12 pH, which eliminates the need for a sample conditioning system. The total chlorine sensor graphically displays both the total chlorine and pH levels for easy trend analysis.

The DC80 Analyser is available with either 110-240 VAC or 24 VDC power. The standard configuration features dual measurements, two 4-20 mA outputs and three alarm relays. The user friendly DC80 also is available with an auto clean option that includes a solenoid actuated spray cleaner using either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.

The plug-n-play TC-80 Total Chlorine Analyser from Electro-Chemical Devices (ECD) offers simplified monitoring for water and treatment processes, easy installation and less maintenance for lower ownership costs. The analyser monitors total chlorine in drinking water, rinse water, cooling water or other fresh water samples from 0.05–20 ppm chlorine as the standard range or 0.005–2.000 ppm with the low-range sensor.

The advanced panel-mount design includes built-in flow control, eliminating the need for complicated pressure regulators and rotameters. Built-in automatic pH compensation also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.

The device is ready to use after connecting the sample and drain lines, then the power and outputs. The TC-80 is calibrated at the factory before shipment, with calibration accomplished by DPD comparison.

The TCA sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC-80’s pH sensor provides accurate compensation for samples between pH 4 and pH 12, eliminating the need for expensive sample conditioning systems to control the pH of the solution.

Amperometric chlorine sensors are flow sensitive — the minimum required flow by the sensor is 0.5 ft/s, above this value the output is virtually flow independent. A ‘constant head’ flow controller maintains the optimum flow by the sensor over a wide range of incoming sample flow rates. The minimum flow required is 10 gal/h, and the maximum flow rate is 80 gal/h with the sample going to drain at atmospheric pressure.

The device is available with either 110–240 VAC or 24 VDC power.

Automation.com, Analyzers’ Solutions Measure Total Organic Carbon, Jan. 28

/in /by

Jan. 27, 2021 – Anaheim, Calif. – Plant engineers responsible for water and wastewater treatment in municipal and industrial plants will find that Electro-Chemical Devices (ECD) now offers them two different highly accurate and reliable solutions to measuring total organic carbon (TOC) levels to protect water quality.

Organic compounds are found in almost all types of water–from natural and treated drinking water to process water, cooling water, and water used in pharmaceuticals and food production. Too much organic contamination in the water interferes with many municipal and industrial processes. For example, when disinfecting drinking water an excess of organic matter can foster microbiological growth or indicate the presence of other undesirable byproducts.

Measuring TOC levels continuously with online analyzers is a highly effective, dependable way to monitor water and wastewater for hazardous contaminants. Depending on the plant, the process and the water quality requirements, plant engineers typically select one of the industry’s two most popular sensing techniques to measure TOC.

The ECD Model 3S TOC Analyzer measures TOC using the UV persulfate oxidation method with carbon dioxide detection by nondispersive infrared absorption (NDIR). In comparison, the ECD Model UV-6 TOC Analyzer measures TOC levels with a UV absorption correlation technique. Both ECD analyzer models provide excellent TOC measurement accuracy and repeatability to ensure compliance with water quality standards.

ECD model 3S TOC analyzer

ECD’s Model 3S TOC Analyzer measures TOC in liquid samples ranging from 0–5 mg/L to 20,000 mg/L. The UV persulfate oxidation method conforms to EPA, DIN, CE, ASTM, and NAMUR regulations as well as meeting the requirements of ISO and EN directives.

The highly dependable Model 3S TOC Analyzer features a fast-loop reservoir with a floating level sensor. If no sample reaches the reservoir for more than a pre-set time, the analyzer switches automatically to standby mode. As soon as the sample flow re-starts, the analyzer switches back to the analysis cycle automatically. Air bubbles are removed in the reservoir before the sample enters the analyzer.

The sample first is 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 a NDIR analyzer to determine TOC levels.

Model UV-6 TOC analyzer

An alternative TOC analytical method is the UV correlation technique performed by the ECD UV-6 Analyzer. The analyzer is factory configured by ECD to measure TOC as correlated with the 254 nm wavelength and the final correlated calibration is done by matching the TOC measured to the on-site grab sample TOC value.

The Model UV-6 Analyzers are a family of on-line sampling analyzers that use UV absorption to perform an analysis. The analyzers are configured to perform analysis over a wide range of values for each parameter measured, nitrate, color, or the correlation at 254 nm wavelength for TOC, COD or BOD.

This technique measures TOC based on the measurement of UV absorption in the sample. The absorbance of the solution or gas is measured though a quartz flow cell at the chosen parameter’s specific wavelength using a long life Xenon light source and photo-detectors. The absorbance level is related to the sample concentration according to the “Beer-Lambert Law.”

The UV6 Analyzer features an easy-to-use reagent-less design. The UV spectroscopy measuring principle requires no chemical reagent resulting in very low operating and maintenance costs. There are no reagent chemicals to order, store, track and dispose at the end of their useful life, simplifying the entire process.

Ideal for Municipal Wastewater Treatment Plants

Anaheim, CA—August 25—2020—Engineers at municipal wastewater treatment plants tasked with the removal of ammonia will find the versatile CA-6 Colorimetric Ammonia Analyzer from Electro-Chemical Devices (ECD) helps them protect water quality with confidence prior to releasing effluent into re-use systems, groundwater recharge basins and surface water systems.

Exposure to ammonia over time is toxic to aquatic life. The U.S. Environmental Protection Agency (EPA) recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments. Total ammonia levels, at this limit, can range from 160 ppm at a pH6 level and at temperature of 41°F (5°C) to 0.06 ppm at a pH9 level and temperature of 77°F (25°C).

Wastewater treatment plants frequently use the Nitrification method to remove ammonia. Nitrification is a two-step process for removing ammonia from wastewater using two different types of autotrophic bacteria that oxidize ammonia to nitrite (nitrosomonas) and then oxidize nitrite to nitrate (nitrobacter).

The ECD CA-6 Ammonia Analyzers help plant technicians determine the effectiveness of the treatment process prior to effluent discharge. With its adjustable cycle time, the CA-6 Ammonia Analyzer reduces the cost of treatment by minimizing the use of consumable reagents while still getting the job done effectively. Technician time is reduced as well, freeing staff for other important tasks.

The CA-6 Analyzer is an on-line sequential sampling analyzer. It automatically performs a controlled sequence of sampling, analysis and then results processing is performed and repeated using colorimetric methods with a reagent. The colorimetric method of water analysis relies on an LED light source and a heated colorimetric cell, which has been designed for measuring trace amounts of Ammonia in water.

The versatile CA-6 Colorimetric Analyzer can be configured to measure Ammonia or a wide range of other substances with a choice of multiple parameters: ppb, ppm and mg/L. It measures Ammonia over a wide range from trace 0 to 50 mg/L. Three separate Ammonia measurement ranges are available: 0 to 1.0 mg/L, 0 to 10 mg/L and 0 to 50 mg/L.

The CA-6 Colorimeters make two measurements during an analysis cycle. The first measurement is of the raw sample which sets the base line for the compensation of color, turbidity and optical characteristics of the cell. The second measurement occurs after the color forming reagents have been added to the sample, mixed and adequate time has passed to allow for color formation. The concentration is calculated using the difference between the two absorbance measurements and the stored calibration information in the analyzer.

The CA-6 Colorimetric Analyzer is equipped with a graphic touchscreen interface showing measured values and status information. It provides users with easy access to menus and functions in multiple languages. There is an integrated data logger onboard with USB download capability for history tracking.

The display’s home screen shows the measured parameter, the status, % reagent volumes, time and Menu choices. The on screen HELP menu includes information on Start Up, Shut Down, Start/Stop Commands, Calibration, Function List, Programing, Maintenance and Troubleshoo1ng.

Outputs provided with the CA-6 Analyzer include two 4-20 mA outputs for measured data, and it also includes a Modbus compatible RS485 RTU. Four programmable SPDT relays are available to provide alarm capability.

The CA-6 Colorimetric Analyzers is designed with two compartments that separate critical electronics from the wet process. The standard model is recommended for indoor use and rated NEMA IP54 for dust and water ingress. The operating temperature range of the CA-6 Analyzer is 41 to 113 °F (5 to 45°C).

Process and plant engineers will find the high-temperature, high-pressure CSX2 Conductivity Analyzer from Electro-Chemical Devices (ECD) helps ensure boiler performance while minimizing maintenance, repairs and extending life in a wide range of critical industrial applications requiring water heating and steam.

The versatile, go-almost-anywhere high-temperature, high-pressure CSX2 Conductivity Analyzer is designed for service to 392°F (200°C) and 250 psig, or 212°F (100°C) and 400 psig. This insertion style 0.75-inch MNPT, 316 stainless steel sensor has PEEK insulators and is available with or without an integral signal conditioner.

The Model CSX2 Conductivity Analyzer measures conductivity over a wide range from 1.0 μS to 50 mS. For accurate measurement and dependable performance, it features built-in sensor temperature compensation that adjusts automatically over installed temperatures from 0>- 392>°F (0>-200>°C).

Hot water is a severe environment for any elastomer. The Model CSX2’s front EPR O-ring seals bear the brunt of the chemical attack, allowing the back seals to remain relatively unaffected. This redundant design increases the reliability of the CSX2, dramatically increasing the usable lifetime of the sensor in these harsh applications.

The Model CSX2’s aluminum junction box is mounted on the rear of the sensor, containing a terminal block and optional signal conditioner. It is an ideal choice for boiler control applications, blowdown control, condensate monitoring, leak detection on heat exchangers and steam purity measurements.

The optional signal conditioner amplifies the conductivity signal, allowing noise-free transmission for hundreds of feet. A wide range of signal conditioners are available for the CSX2 sensor to optimize the conductivity measurement at specific ranges. The ECD Model LQ800 Multi-Channel Controller or the T80 Transmitter have a user specified signal conditioner that is mounted inside the CSX2 instrument or optionally in a remote junction box.

The measurement of conductivity and resistivity in liquid water-based solutions is an essential requirement in a wide range of industrial processes. Conductivity and resistivity measure the electrical conductivity of a solution, which correlates to the purity of the water or the amount of dissolved ions in the liquid.

Accurate, reliable conductivity data is important when either recycling water for re-use within the plant to protect sensitive equipment from internal corrosion (scale) and/or when discharging water from the plant into wastewater treatment systems. The data helps ensure the effluent meets local, state and federal water quality standards to avoid plant shutdowns and costly fines.

ENHANCING WASTEWATER AMMONIA TREATMENT WITH ECONOMICAL CA-6 COLORIMETRIC ANALYZER

/in /by

Engineers at municipal wastewater treatment plants tasked with the removal of ammonia will find the versatile CA-6 Colorimetric Ammonia Analyzer from Electro-Chemical Devices (ECD) helps them protect water quality with confidence prior to releasing effluent into re-use systems, groundwater recharge basins and surface water systems.

Exposure to ammonia over time is toxic to aquatic life. The U.S. Environmental Protection Agency (EPA) recommends a limit of 0.02 ppm as NH3 in freshwater or marine environments. Total ammonia levels, at this limit, can range from 160 ppm at a pH6 level and at temperature of 41°F (5°C) to 0.06 ppm at a pH9 level and temperature of 77°F (25°C).

Wastewater treatment plants frequently use the Nitrification method to remove ammonia. Nitrification is a two-step process for removing ammonia from wastewater using two different types of autotrophic bacteria that oxidize ammonia to nitrite (nitrosomonas) and then oxidize nitrite to nitrate (nitrobacter).
