Two Ways to Measure TOC Levels in Water: UV Persulfate NDIR Vs UV Correlation

Ideal for monitoring accidental spills, contamination and treated discharges

Anaheim, CA—January 27, 2021—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 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.

Family of Chlorine Analyzers Provides Total Solution To Water Disinfection & Water Quality Applications

Ideal for Muni Water/Wastewater, Electric Power Generation, Electronic Components and Equipment, Food/Beverage, Oil/Gas, Pharmaceutical, Pulp/Paper, Saltwater AC

Anaheim, CA—July 26—2021—Keeping it clean and safe while protecting both people and the environment, the broad family of Chlorine Analyzers from Electro-Chemical Devices (ECD) offers process and plant engineers multiple highly accurate, dependable disinfection and water quality measurement solutions that are easy to install, require minimal maintenance and offer a long-life at a low lifecycle cost.

Designed with advanced amperometric chlorine sensors, ECD’s panel-mounted family of chlorine (Cl2) sensors and full analyzer systems support a wide range of applications for municipal and industrial water disinfection, water quality purification and wastewater effluent treatment. Their highly intelligent, full-featured sensors come factory pre-calibrated, and their versatile transmitters are mounted on a robust front panel with plug-and-play capability, which takes technicians only minutes to install: simply mount, plumb, plug-in and turn-on.

CD80 Chlorine Dioxide

The CD80 Chlorine Dioxide (ClO2) Analyzer is designed to monitor free chlorine in drinking water, rinse water, cooling water or other fresh water samples over a standard range from 0.05 to 20 ppm, or 0.01 to 5.00 ppm with the low range sensor. The CD80 is compliant with EPA Method 334.0 for measuring drinking water. CL02 exists as a gas in solution; it does not dissolve like other chlorine compounds and is therefore unaffected by the pH of the solution.

TC80 Total Chlorine

The TC80 Total Chlorine Analyzer monitors total chlorine in drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine in a standard range of 0 to 20 ppm. Its versatile three-electrode amperometric sensor design also can be specified to measure all chlorine species in the water, combining chlorine and free chlorine in a high range of 0.05 to 20 ppm or a low range of 0.005 to 2.000 ppm.

FC80 and FCX80 Free Chlorine

The FC80 Free Chlorine Analyzer and the FM- and ATEX-approved explosion-resistant Model FCX80 are designed to monitor free chlorine (residual chlorine) in municipal drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine. They are available in two optional configurations: either a hi-range of 0.05 to 20 ppm or a low-range of 0.01 to 5.00 ppm unit. They are compliant with EPA Method 334.0

DC80 DeChlorination Analyzer

ECD’s DC80 De-Chlorination Analyzer monitors very low levels of total chlorine (TC) in water that indicates the chlorine has been removed before discharge or release into the environment. It uses a “zero shift” strategy to make the measurement. Since the total chlorine amperometric needs some amount of chlorine for a stable reading, a pump supplies a constant 3 to 5 ppm of total chlorine and the analyzer “zeros” out this offset to measure the difference of the water to be measured compared to the total chlorine supplied.
DCA23 Seawater DeChlorination Analyzer

The DCA23 Seawater DeChlorination Analyzer monitors the chlorination and/or dechlorination of sea water from 0.00 to 2.00 ppm. Sea water is used for cooling in power plants, refineries and salt water air conditioning systems. The analyzer displays the Cl2 ppm level to conform with environmental regulations, and it actually measures the total residual oxidant (TRO) and converts it into an equivalent ppm of chlorine. TRO is defined as the total oxidizing capacity (free and combined) of the sea water that is available after chlorination.

Cloud-Ready LQ800 Multi-Channel Control System For Municipal Water Monitoring and Treatment

Ideal for Water Storage, Treatment and Distribution

Anaheim, CA—June 29, 2021—Engineers responsible for municipal ground or surface drinking water supplies, storage, treatment and distribution systems in remote locations or close to population centers will find the modular, Cloud-ready LQ800 Multi-Channel Control System offers them a complete measurement and control solution that provides over 50 analytical measurements, as well as liquid flow, level and temperature data.

Industrial Boiler Water Treatment Systems Rely On Multifunction Analyzer with Cation Sensors

Electric Power Generation, Electronic Components, Oil/Gas Refining, Water Re-Use

Anaheim, CA—May 25, 2021—Process and plant engineers responsible for contaminant-free in-plant water treatment systems for heating, cooling, rinsing, washing and effluent treatment will find that the CE800 Series Analyzers from Electro-Chemical Devices (ECD) detect a wide range of contaminants, which contribute to the build-up of corrosion and scale in boilers, turbines, piping and other expensive equipment that requires maintenance and shortens life.

The ECD CE800 Series Analyzers are a family of on-line cation conductivity analyzers. Cation conductivity, also known as acid conductivity and conductivity after cation exchange, is the measure of electrolytic conductivity of a liquid sample after that liquid sample has passed through an ion exchange resin column containing cation resin. The conductivity of makeup water, feed water and condensate after passing through this column of strongly acid cation exchanger resin is an important chemical measurement used in steam generating power and other industrial plants depending on boilers for steam process heating and/or plant HVAC.

The CE800 Cation Conductivity Analyzers also measure pH, which provides an additional parameter of importance to ensure water quality of the plant. The cation resin converts low conductivity mineral ions such as sodium (NA+), calcium (Ca++) and magnesium (Mg++) to form an acid, which has a high conductivity level hydrogen ion (H+). As this acid form has a conductivity that is three- to six-times greater than the corresponding salt, the sensor is much more sensitive, effective and reliable in measuring water impurities than other methods.

Oxygen (O2) scavengers, such as ammonia and amines, which skew to high values, are removed af¬ter exposure to the cation resin. This method provides an accurate indication measurement of impurities in the medium. The CE800 also has the option to measure pH levels using ECD S80 high purity water electrode sensor. Measuring pH levels provides a secondary indication of possible water contamination.

The CE800 Analyzer is available as a panel mount or enclosure system with the option of one or two channel measurement streams. The CE 800 is highly customizable and can be tailored to meet individual plant or unique process needs. The CE800 features ECD’s highly intelligent T80 Transmitter and S80 Sensor (resistivity, conductivity, or pH) along with a refillable cation resin column. The precision S80 Sensor digitally communicates with the T80 Transmitter, automatically configuring the transmitter’s menus and display screens to the chosen parameter, including conductivity, resistivity, pH, dissolved oxygen, ORP and specific ions.

ECD’s “plug-and-play” CE800 Cation Conductivity Analyzers are easy to start up and use, simply connect the sample lines and then power up the factory calibrated analyzer. Enclosure with wall mounting hardware is standard. The analyzer utilizes the complete capabilities of the ECD T80 Transmitters and S80 sensors for conductivity and pH or other measurement capabilities if so desired.

The CE800 system is available with the 24 VDC or 110/220 VAC with optional alarm relay and digital bus communications (MODBUS RTU or Hart). The T80 Transmitter features an easy-to-read LCD graphic display with numerical information. The menu structure is highly intuitive, easy to navigate and configure. There are no special tools needed or complex training required prior to installation. Typically, a single technician requires no more than 30 to 45 minutes for set-up the system.

Dual Function TR82 Analyzer Detects and Measures Turbidity in Either Clear Water or Wastewater

Ideal for Both Industrial Process and Municipal Water and Wastewater Treatment

Anaheim, CA—September 1—2021—With its precision nephelometric turbidity sensor designed for use in either municipal or industrial water and wastewater treatment systems, the versatile, next-gen TR82 Turbidity Analyzer from Electro-Chemical Devices (ECD) gives process and plant engineers a highly accurate and dependable solution to ensure that their treatment systems are performing at high efficiency and at the lowest cost to serve a wide range of needs.

The TR82 Turbidity Analyzer with its clear water sensor is designed for use in all phases of drinking water treatment and disinfection. It is ideal for monitoring ground water sources or surface water storage lakes, basins lagoons or ponds, as well as in the control of clear rinse water and in filter rupture or backwash monitoring systems.

The TR82 Analyzer’s suspended solids sensor supports both industrial process and municipal water and waste treatment. In food/beverage plants, for example, the TR82 Analyzer is ideal for mixing and blending, and in paper manufacturing it monitors filtrates. The TR82 also supports municipal wastewater activated and digested sludge treatments before effluent release.

The Triton TR82 uses the optical method for determining the turbidity. 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, and the size and composition of the suspended particles.

The Triton TR82 features a near infrared LED light source and the 90-degree scattered light method in accordance with ISO 7027/EN 27027 to assure accurate turbidity values under standardized and comparable conditions. The TR82 response (and measurement data) depends on the size, shape and composition of the suspended particles.

The Triton TR82’s factory calibrated clear water and suspended solids sensors are available in four different standard measurement ranges: < 30 NTU, 0-1000 NTU, 0-4000 NTU and 0-5000 mg/l. In mud the available range is 5000-10,000 mg/l, and in sand the range is 50,000-100,000 mg/l. Custom ranges are available upon request.

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 monitoring with analyzers such as the TR82 with its dual sensor capability for both clear treated water and suspended solids monitoring has become a critical indicator of the overall water quality. In addition to protect the environment prior to treated effluent release back into the environment, water-based process plant technicians must test for turbidity to protect a wide range of plant and animal species from the hazards of contaminated water.

The TR82’s intelligent turbidity sensor technology stores the user’s chosen standard or factory custom calibration range, including self-diagnostics to alert technicians when adjustments or maintenance are necessary. These plug-and-play turbidity sensors connect seamlessly with ECD’s T80 Universal Transmitter. This transmitter comes with a choice of MODBUS, HART, 4 to 20 mA and/or relay outputs for multiple connection options to local programmable logic controllers (PLCs) and/or distributed control systems.

The T80 Transmitter can be configured as either a single or dual channel controller with one or two 4-20 mA outputs with MODBUS RTU and optional three alarm relays or HART 7 communication. The T80 Transmitter allows the turbidity or suspended solids measurement to be combined with other measurements using the ECD S80 pH, ORP, pIon, Conductivity or DO82 Dissolved Oxygen sensors and other ECD sensors.

Installing the TR82 Turbidity Analyzer is simple and straightforward with a choice of configurations available. A basic installation requires a 1-inch stand pipe for immersion service, or a PVC flow cell for an in line flow-through application, valve retractable, or a de-bubbler for micro air bubble applications.

Optimizing Boiler Performance & Extending Life With High-Temp, High-Pressure CSX2 Conductivity Analyzer

AA038726

Anaheim, CA—September 30—2020—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.

Anaheim, CA—October 27—2020—Engineers and technicians working to prevent the spread of viruses and bacteria at municipal as well as industrial water and wastewater treatment plants will want to learn more about the highly accurate, reliable sensing technologies available with the Family of Disinfection Analyzers from Electro-Chemical Devices (ECD).

Relying on reagentless amperometric chlorine, hydrogen peroxide and peracetic acid sensing technologies, ECD’s panel-mounted disinfection analyzers support a wide range of water purification and treatment applications. Their highly intelligent, full-featured transmitters are conveniently located on the front panel with plug-and-play capability that takes technicians only minutes to install: simply mount, plumb, plug-in and turn-on.

The FC80 Free Chlorine, TC80 Total Chlorine, HP80 Hydrogen Peroxide and PA80 Peracetic Acid analyzers all come pre-calibrated from the factory in a choice of multiple ranges. They monitor the effectiveness of water treatment systems and validate that they are doing their job to help prevent the spread of viruses, bacteria and other dangerous pathogens in drinking water, rinse water, wash-down water, cooling water and wastewater effluent.

In addition, their reagentless sensor design reduces the total lifecycle costs of these analyzers. The cost of reagents can be a considerable expense over the life of an analyzer and technicians must also regularly monitor reagent consumption and then refill. The inactive reagents at their end-of-life are toxic materials, which require special handling with higher disposal costs.

The FC80 Free Chlorine Analyzer is designed to monitor free chlorine (residual chlorine) in municipal drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine. It is available in two optional configurations: either a hi-range of 0.05-20 ppm or a low-range of 0.01 to 5.00 ppm unit. It is compliant with EPA Method 334.0

The TC80 Total Chlorine Analyzer monitors total chlorine in drinking water, industrial cooling and rinse water, wastewater or other fresh water samples containing chlorine in the range of 0-20 ppm. Its versatile three-electrode amperometric sensor design also can be specified to measure all chlorine species in the water, combining chlorine and free chlorine in a high range of 0.05 to 20 ppm or a low range of 0.005 to 2.000 ppm.

The PA80 Analyzer monitors peracetic acid (PAA) in the food, beverage, medical and pharmaceutical industries, as well as in industrial process cooling towers and municipal wastewater treatment. Peracetic acid is a colorless liquid with a characteristic pungent odor similar to vinegar. PAA is a strong oxidizer, stronger than either chlorine or chlorine dioxide. It is available in a choice of three ranges: 0 to 20 ppm or 0 to 200 ppm and 0 to 2000 ppm. PAA is

The HP80 Analyzer is designed to monitor hydrogen peroxide (H2O2) in water in two ranges: either 0 to 200 ppm or 0-20.0% H2O2. HP is widely used in the pulp/paper industry as a bleaching agent, as an oxidizer to remove metals from well water, as a disinfectant for industrial cooling water towers and in municipal wastewater treatment effluent. HP is a colorless liquid that in high concentrations gives off an irritating acidic odor. It is a strong oxidizer, stronger than either chlorine or chlorine dioxide.

No matter the water treatment or purification application, there is a solution with the ECD family of disinfection analyzers. They’re all designed for accuracy, reliability, long-life and low cost of ownership with their reagentless, low-maintenance amperometric sensors and intelligent transmitter with two 4-20 mA outputs, three alarm relays and MODBUS RTU.

Enhancing Wastewater Ammonia Treatment With Economical CA-6 Colorimetric Analyzer

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).

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 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.

Electro-Chemical Devices introduces CA-6 Colorimetric copper analyzer

Process and plant engineers treating municipal drinking water or industrial wastewater who need to monitor, remediate or remove harsh Iron (Fe) can use the precision CA-6 Colorimetric Copper Analyzer from  Electro-Chemical Devices (ECD) with the goal to achieve desired water quality levels and protect water resources.

With its adjustable cycle time that minimizes reagent use and maintenance, the CA-6 Colorimetric Analyzer is a solution to iron or other undesirable minerals. Iron ores are among the earth’s most common elements.  The human body requires iron for good health, but too much iron causes health problems as well.  While for industrial plant applications, too much iron can be a sign of process impurities, pipe corrosion or discharge effluent issues.

The U.S. Environmental Protection Agency (EPA) through its National Secondary Drinking Water Regulations (NSDWRs) recommends that Fe levels not exceed 0.3 mg/L.  The EPA’s NSDWRs are non-enforceable guidelines for contaminants that may cause cosmetic effects (skin or tooth discoloration) or aesthetic effects (taste, odor, or color).

ECD’s CA-6 Iron 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 ferrozine 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 Fe in water.

The CA-6 Colorimetric Analyzer measures Fe using the differential photometric absorbance method.  In an acid buffered solution, ferrozine and iron react to form a purple colored complex measured at 572 nm.  The light absorption intensity is proportional to the iron concentration level in the water sample.

The CA-6 Colorimetric Analyzer can be configured to measure iron or a range of other substances with a choice of multiple parameters:  ppb, ppm and mg/L.  It measures iron over a wide range from trace ug/L to 10 mg/L.  Three separate measurement ranges are available depending on the chosen cell size: 2 to 250 ppb (26 mm cell), 9 to 500 ppb (16 mm cell) and up to 10 mg/L with an internal dilution module.

The CA-6 Iron Analyzer consumes its ferrozine reagent at 2.5L (0.66 US.gal) for the 16 mm cell and 5L (1.32 US gal) for the 26 mm cell.

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.

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).

Water treatment engineers tasked with assuring reliable potable water treatment from ground or surface sources and storage reservoirs as well as those responsible for suspended solids in municipal or industrial wastewater effluent will find the smart TR80 Turbidity Analyzer from Electro-Chemical Devices (ECD), offers them a flexible and economical solution to safe drinking water or treated effluent suitable for release or re-use.

The new, versatile Triton TR80 Turbidity Analyzer 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.

The advanced Triton TR80 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 provide high sensitivity for turbid conditions over the entire measurement sample range.

Next-Gen Optical Turbidity Analyzer

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). It can take the pressure too, with a choice of multiple flow cell configurations available that withstand a range of up to 50 psi (3.5 bar maximum). The sensor body features wetted materials of CPVC or optionally POLYPRO® polypropylene material.

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.
