Anaheim, CA—March, 21, 2022—Municipal water engineers mandated to monitor Chromium VI in drinking water will find the CA6 Colorimetric Analyzer from Electro-Chemical Devices provides precise and dependable measurement data to ensure compliance with local, state and federal drinking water safety standards.

According to the U.S. Environmental Protection Agency (EPA), chromium is an odorless and tasteless metallic element that is found naturally in rocks, plants, soil and volcanic dust, and animals. The most common forms of chromium that occur in natural waters in the environment are trivalent chromium (chromium III) and hexavalent chromium (chromium VI.)

An essential human dietary element, chromium III is found in many vegetables, fruits, meats, grains, and yeast. chromium VI, however, while it occurs naturally in the environment from the erosion of natural chromium deposits, but it also can be produced by industrial processes. There are demonstrated instances of chromium VI being released into the environment by leakage, poor storage, or inadequate industrial waste disposal practices.

Chromium VI continues to be a potential health risk. The U.S. EPA’s assumes that any measurement of total chromium is 100 percent chromium VI, which is the toxic form. If tap water from a public water system exceeds this federal standard, consumers will be notified.

ECD’s Model CA6 Colorimetric Analyzer is an on-line sequential sampling analyzer that is designed to monitor chromium VI in drinking water. It can be configured to measure chromium VI in three separate ranges: 0 to 1.0 mg/L, 0 to 10.0 mg/L or 0 to 50.0 mg/L

The CA6 Colorimetric Analyzer’s sequence of sampling, analysis and results processing is performed and repeated using colorimetric methods for high accuracy and reliability. This technology relies on an LED light source and a heated colorimetric cell designed for measuring trace amounts of manganese, iron and other analytes in water.

The CA6 analyzer is lightweight and easy to install. Weighing less than 40 pounds, it can be wall mounted or simply set on a bench using the optional bench top stand. After the sample, waste and reagent lines have been connected to the analyzer and provided with power, the CA6 will begin its preprogrammed analysis sequence.

The CA6 offers up to four separate channels (optional) each from a separate sample point. A simple, user-friendly menu structure and touchscreen interface makes it easy to access information or customize analyses.

Relying on photometric differential absorbance, the versatile CA6 Analyzer monitors chromium VI levels and over 20 other common parameters including: aluminum, iron, manganese, silica, nitrogen, iron and sulfate. It operates at a wide temperature range of 5-50°C and offers repeatability of ±2% on the absorbance value if the turbidity <80 NTU and drift of ±2% per month on the absorbance measurement.

TOC Analyzer Helps Muni Wastewater Plants Monitor Treated Effluent To Meet Environmental Regulations

/in /by

Anaheim, CA—November 10, 2022—Municipal wastewater plant engineers and managers will find the Total Organic Carbon (TOC) Analyzer from Electro-Chemical Devices (ECD) helps them measure carbon levels more accurately in order to ensure effective treatment, to monitor post treatment effluent and to meet federal, state and local water environmental regulations.

ECD’s TOC Analyzer, with its UV persulfate non-dispersive infrared (NDIR) detection technology, helps plant engineers and technicians know with confidence that their wastewater treatment process is effective and that the job is complete. In addition to municipal wastewater treatment plant applications, the TOC Analyzer is also suitable for monitoring stormwater and other types of industrial water-based waste streams or for water re-use treatment applications.

In surface water, ground water, municipal wastewater or industrial wastewater, organic matter is generally present at various levels and needs to be measured and treated. Knowing the TOC level is especially important for effectively treating municipal wastewater and stormwater flows prior to plant effluent release in order to prevent the contamination of streams, rivers, lakes and ponds where sensitive wildlife including plants, fish and other aquatic creatures are present.

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 levels ranging from 0-5 mg/L to 20,000 mg/L.

The unique design of ECD’s TOC Analyzer features a valve-free sample line, which largely eliminates blockages to help assure nearly continuous operation. 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.

When compared 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.

Developed for rugged, demanding plant environments, the ECD TOC Analyzer is housed in a dual compartment enclosure. The isolated 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.

Simple to install and easy to use, 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.

Anaheim, CA—September 22, 2022—With its reagent-less amperometric sensor design, the highly accurate TC80 Total Chlorine Analyzer from Electro-Chemical Devices (ECD) eliminates consumables, simplifies installation and reduces maintenance to lower the total cost of instrument ownership over its long life.

ECD’s TC80 Total Chlorine Analyzer is a panel mounted, ready-to-use right out of the box instrument that’s compliant with the U.S. Environmental Protection Agency’s (EPA) Method 334.0. Its versatile design monitors total chlorine in drinking water, industrial cooling and rinse water, wastewater or other disinfected fresh water samples that contain chlorine over a wide range that can be scaled depending on the user’s needs.

The TC80 Cl2 Analyzer’s total chlorine sensor is a precision three-electrode amperometric sensor, which measures all chlorine species in the water, combined chlorine and free chlorine. It is available in either: (1) a standard high-range configuration measuring Cl2 from 0.05 to 20 ppm or (2) a standard low-range configuration of 0.005 to 2.000 ppm. The analyzer comes factory pre-calibrated to the chosen measurement range before shipment, which speeds set-up.

Total chlorine is defined as the combined amount of free chlorine, chloramine, organic and bound chlorine in a water sample. The TC80’s Cl2 sensor is a three-electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC80’s built-in 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.

This complete TC80 Cl2 Analyzer solution thus requires no additional third-party components. Everything needed comes in one box and is assembled on a panel mount board. The plumb-plug-and-play design incorporates a flow control device, the pH sensor, the chlorine sensor and the highly intelligent T80 transmitter, which are all conveniently mounted on the instrument’s ready-to-mount PVC panel.

No special technician training or tools are required for installing the TC80 Cl2 Analyzer.

Two-in-One Sensor for Nutrient Nitrogen Monitoring In Wastewater Effluent and Surface Water Storage

/in /by

Integrated Ion Selective Electrode (ISE) Sensor Provides Double-Play Capability

 

Anaheim, CA—July 19, 2022—Designed to monitor nitrogen (NH4) as ammonium or as nitrate, the versatile family of HYDRA-DS Analyzers from Electro-Chemical Devices (ECD) simplifies the accurate measurement of harmful nutrients in wastewater treatment effluent flows and in surface water storage systems, including ponds, lakes, reservoirs, canals and streams.

ECD’s family of HYDRA-DS Analyzers features a precision ion selective electrode (ISE) sensor, which is designed for multiple parameter nutrient nitrogen water quality measurements. This versatile double-duty ISE sensor seamlessly connects with either ECD’s intelligent T80 Transmitter or LQ800 Multi-Channel Transmitter, for highly effective and economical nutrient management.

The HYDRA-DS family of plug-n-play analyzers relies on ISE sensors with digital signal conditioners for the trouble-free measurement of ammonium as nitrogen (NH4+-N) and/or the measurement of nitrate as nitrogen (NO3–-N). They include auto-compensation circuitry for interfering ions and temperature compensation, rugged PVC construction with easily replaceable electrodes and a built-in spray cleaner that minimizes expensive technician maintenance for a lowest total cost of ownership.

In municipal wastewater treatment applications, the HYDRA-DS Analyzers are ideal for aeration basins, primary or secondary clarifiers, denitrification and final effluent monitoring.  For environmental waters, they are useful in water storage applications such as lakes, reservoirs or ponds and to control nutrients from agricultural run-off flows into canals, storage basins and ground water aquafers and wells.

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.

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.

Anaheim, CA—March, 17, 2022—Monitoring, balancing and maintaining alkaline and pH levels for municipal drinking and industrial process water applications is now simpler and more reliable with the advanced CA900 Titration Analyzer, which automates routine alkalinity measurement with a more cost-effective approach.

Water quality depends on maintaining the proper balance of pH and alkalinity levels, which is essential in everything from drinking water production to wastewater processes, as well as in irrigation water, water-based beverages, pharmaceuticals, electronics manufacturing and more. Alkalinity is the measure of the capacity of water to neutralize acids and affects pH levels in water. It occurs naturally in ground water and its levels are influenced by rocks and soils, salts, certain plant activities and in some cases by industrial wastewater discharges.

Titration analysis with ECD’s sophisticate CA900 Analyzer calculates alkalinity by dispensing known doses of a titrant fluid into a reaction cell while monitoring the pH level to its end point. The analyzer then uses the titrant concentration and amount dispensed to calculate the level of alkalinity in the sample.

The CA900 Titration Analyzer typically performs a single alkalinity measurement per analysis cycle. Its standard program sequence consists of a cleaning cycle, sample acquisition, monitoring of pH, the addition of the titrant fluid, mixing the fluid, calculation of results and data storage. The desired frequency of analysis between cycles can be easily modified to the requirements of the user’s process.

Measuring alkalinity levels with ECD’s CA900 Titration Analyzer is especially important for the effective treatment of both municipal drinking water and wastewater, where it can affect the wastewater anaerobic digestion process. Alkalinity in surface water generally results from the presence of calcium carbonate, CaCO3, which has been leached from rocks and soil and then enters surface or ground water systems.

The highly intelligent CA900 Titration Analyzer from ECD simplifies and automates alkalinity measurement. Technicians can easily install and start up the CA900 Titration Analyzer in less than 15 minutes with no special tools or hours of training. It’s as easy as connecting the sample, the waste and reagent lines and then powering up the factory pre-calibrated analyzer. Wall mounting hardware comes standard with each analyzer, but an optional bench top stand with reagent holder also is available.

ECD’s CA900 Titration Analyzer features a choice of four different factory pre-set alkalinity calibration ranges: 0 to 50 ppm, 50 to 200 ppm, 200-1000 ppm, and 0 to>1000 ppm. Users simply order the desired calibration range, and the analyzer comes ready to go right out of the box. The analyzer’s full-featured design also comes with four 4-20 analog outputs, an Ethernet digital output and four user-configurable alarm relays.

Accessing information or customizing analysis routines are both easily accomplished with the CA900 Titration Analyzer’s user-friendly menu structure and touchscreen interface. The analyzer also can be web-enabled as a powerful internet of things (IoT) tool for remote monitoring and interfacing with personal handheld devices such as controllers, mobile phones, tablets, laptops and computers.

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

/in /by

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.

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

/in /by

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.
