Versatile Optical IR Sensing Turbidity Analyzer With Modular Multi-Parameter Measurement

Simplifies Suspended Solids Environmental Monitoring, Wastewater Treatment Discharge,

Filter or Backwash, Clarity in Settling Ponds, Surface Water, Rinse Water Control

 

Irvine, CA—August 11, 2016—With its optical infrared (IR) sensor and intelligent transmitter, the two channel Triton® Turbidity Analyzerfrom Electro-Chemical Devices (ECD) combines precision turbidity analysis with the flexibility to add a second measurement, including dissolved oxygen (DO), pH, oxygen reduction potential (ORP),  conductivity or various pION parameters.

Accurate measurement of turbidity (suspended solids) is important in a wide range of surface water, municipal water and wastewater treatment, and industrial water treatment applications.  Turbidity is the cloudiness or haziness of a water sample, which is caused by suspended particles in the water that are typically clay and silt.  Viruses and bacteria can attach themselves to the particles making turbidity a critical indicator of overall water quality.

ECD’s Turbidity Analyzer is designed with the advanced Triton TR86 Turbidity Sensor and the sophisticated T80 Universal Transmitter.  The result is accurate, reliable turbidity measurement with the capability to add one additional measurement parameter, providing plant technicians with the flexibility to add any of ECD’s intelligent S80 plug-n-play sensors to the process control loop.

The TR86 sensor measures suspended solids continuously in a choice of three separate ranges from 0 to 4000 NTU.  With its optical IR sensing technology, the TR86 sensor emits an 850 nm beam of near infrared light into the sample where it is scattered by the particles suspended in the water.  The amount of back scattered light returning to the sensor is then measured and correlated to the amount of suspended solid particulates in the water.

The measurement response of the TR86 sensor depends on the size, shape and composition of the suspended particles.  For this reason, mg/L, ppm and % suspended solids must be calibrated with the monitored water sample.  Turbidity measurements (NTU, FNU) can be calibrated with calibration standards such as Formazin, StablCal or SDVD beads.

The dependable TR86 sensor is accurate to 2 percent of reading, or 0.5 NTU, whichever is greater.  It features built-in temperature compensation to ensure accuracy and operates over a wide temperature range from 32 to 122°F (-5 to 50°C) and at pressures up to 50 psi maximum in a flow cell configuration.

Designed for rugged wastewater treatment environments, the TR86 sensor is available with either side mounted or front axially mounted optics.  These two options provide technicians with a choice to minimize interference from surfaces below the sensor (side-mount) or from surfaces around the sensor (axial front-mount).    A built-in daylight rejection filter blocks sun light and reduces ambient light interference.  The front mount configuration includes a copper ring sensor surround shield that inhibits the growth of algae and other biological films.

The TR86 sensors plug in directly to the T80 Universal Transmitter and are pre-set at the factory to the desired range. The T80 transmitter functions as either a single or dual channel transmitter with one or two 4-20 mA outputs, MODBUS RTU and optional alarm relays (three) or HART 7 communication.   The T80 transmitter’s highly intelligent electronics allow suspended solids turbidity measurement to be combined with any of ECD’s intelligent S80 sensors for  pH, ORP, conductivity, DO or pION.

Installing the Triton Turbidity Analyzer is simple with a 1-inch stand pipe for immersion service or with ECD’s PVC flow cell for an in-line flow through application.  Either the side-mount or front-mount configuration of the TR86 sensor is suitable for immersion service.  The side mount configuration must be used for in-line service.

Efficient Colorimetric Analyzer Helps Monitor Troublesome Manganese & Iron In Drinking Water

Ideal for Muni Water, Food, Beverage, Textile,

Semiconductor & Other High Purity Water Processes

 

AA038726

Anaheim, CA—June 16, 2016—The easy-to-use and economical CA6 Colorimetric Analyzer from Electro-Chemical Devicesprovides accurate and reliable measurement of manganese (Mn) or iron levels in municipal drinking water production, food/beverage processing and other high purity water processes.

The Model CA6 Colorimetric Analyzer is an on-line sequential sampling analyzer. A sequence of sampling, analysis and results processing is performed and repeated using colorimetric methods. 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.

Manganese and iron are natural occurring elements found in air, soil and water.  Manganese and iron are essential nutrients for humans and animals.  Adverse health effects can be caused by inadequate intake or over exposure.  Manganese deficiency in humans is thought to be rare because manganese is present in many common foods.

Both manganese and iron have a strong, unpleasant metallic taste in water.  Ground water sources with manganese and iron can appear clear initially, but turn black (manganese) and orange-brown (iron) when exposed to air. An advisory from the U.S. Environmental Protection Agency (EPA) recommends reducing manganese and iron concentrations to or below 0.05 mg/L and 0.03 mg/L, respectively, which are the EPA’s secondary maximum contaminant levels (SMCL’s).

The EPA’s manganese and iron SMCL’s are based on staining and taste considerations, but are not federally enforceable regulations and are intended as guidelines. There are multiple municipal water treatment options for the removal of Mn and iron from drinking water.

 

AA038726

They all, however, rely on accurate and dependable water quality analysis prior to and after treatment.  The CA6 Colorimetric Manganese Analyzer is available in three ranges:  0-100 ug/L, 0-1 mg/L and 0-5 mg/L and the CA6 Colorimetric Iron Analyzer also is available in three ranges: 0-0.1 mg/L, 0-1.0 mg/L and 0-5.0 mg/L.

The CA6 precision online sequential sampling 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 is available with up to 4 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.

The CA6 utilizes photometric differential absorbance to analyze manganese, iron and over 20 other common parameters including: aluminum, 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.

The CA6 Analyzer’s easy-to-use touch-screen display shows the measured parameter, analyzer status, percent reagent volumes and the menu bar, which provides access to the run, display, program, service and help menus. It includes two alarm relay outputs and a 4-20 mA channel that connects with programmable logic controllers (PLC’s) or distributed control systems (DCS’s).

The rugged and reliable CA6 features two separate compartments to isolate liquids and electronics and is enclosed in an epoxy powder coated, cold rolled steel cabinet. The liquids enclosure houses all the components necessary for sampling and reagent flow, mixing and reaction stages (sampling pump, reagent micro-pumps and colorimetric reaction cell).

Intelligent Total Chlorine and Free Chlorine Analyzers For Simple, Precise, Reliable Measurement

Ideal for Municipal Water and Wastewater Chlorination Treatment Systems

 

Free Chlorine AnalyzersAnaheim, CA—November 7, 2016—Municipal water treatment process engineers and technicians will find the advanced modular TC80 Total Chlorine and FC80 Free Chlorine Analyzers from Electro-Chemical Devices combine plug-n-play capability for fast set-up, highly reliable accuracy and replacement sensor cartridges for economical maintenance

In drinking water disinfection systems, chlorine is commonly added to remove disease causing organisms.  When the chlorine is added to the water in a treatment facility, some of the chlorine first reacts with organic materials and metals, which leaves it unavailable for disinfection.  This state is typically known as chlorine demand of the water.

The chlorine that remains after accounting for chlorine demand is known as total chlorine (TC).  It consists of the amount of chlorine that has reacted with nitrates (unavailable for disinfection), which are called combined chlorine, and the amount of free chlorine (FC) that is available to treat disease causing organisms.

The measurements of both total chlorine and free chlorine are vitally important in the effective operation of water disinfection systems.  ECD’s intelligent TC80 and FC80 Sensors offer reliable measurement of both parameters along with its modular two-channel T80 Transmitter/Analyzer.

Both the TC80 and FC80 Analyzers are compliant with EPA method 334.0 for measuring drinking water. They feature heavy-duty three electrode amperometric chlorine sensors with a gold cathode, silver halide anode and 304 SS counter electrode. The counter electrode provides a stable base potential that minimizes drift.

The TC80 Analyzer monitors total chlorine in drinking water, rinse water, cooling water or other fresh water samples. The measurement range is from 0.05 – 20 ppm chlorine as the standard range or 0.005 – 2.000 ppm with the low range sensor.

The FC80 Analyzer  monitors free chlorine in drinking water, rinse water, cooling water or other fresh water samples.  The measurement range is from 0.05 – 20 ppm chlorine as the standard range or 0.01 – 5.00 ppm with the low range sensor.

The plug-n-play T80 Analyzer/Transmitter along with the TC80 and FC80 Sensors all install quickly right out of the box.  The TC80 Analyzer/Transmitter’s advanced panel mount design includes built-in flow control, which eliminates the need for complicated pressure regulators and rotometers. Connect the sample and drain lines, connect the power and outputs and the system is ready to use.  Built-in automatic pH compensation also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs

The T80 Analyzer/Transmitter is available with either 110-240 VAC or 24 VDC power.  Parameters can be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two 4-20 mA outputs, three alarm relays and a MODBUS RTU.

An auto-clean option is available 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.

Green Friendly PA80 Peracetic Acid Analyzer Helps Maintain Disinfection Without Harmful By Products

Ideal for Food/Beverage, Medical, Pharmaceutical and Muni Water Processes

PAA AnalyzerAnaheim, CA—February 2016—Process and plant engineers responsible for maintaining sanitary product, process and equipment environments will find the new panel mounted PA80 Peracetic Acid Analyzer from Electro-Chemical Devices (ECD) simplifies process monitoring to ensure disinfection without the need for potentially harmful disinfection byproducts (DPBs).

The plumb-and-play design of ECD’s economical PA80 Peracetic Acid Analyzer allows a single technician to install the unit right out of the box with no special tools or complex calibration routines. Ready to go from the factory, the PA80’s cost-effective design includes built-in flow control, and so there’s no need to purchase or install pressure regulators and rotameters, which are typically an extra cost with many other types of liquid analyzers.

Peracetic acid is a colorless liquid with a characteristic pungent odor similar to vinegar. PAA is produced by a reaction between hydrogen peroxide and acetic acid.  Produced typically as an equilibrium solution combining these agents, PAA is supplied in concentrations of 5 to 15 percent. It is a powerful oxidizer, stronger than either chlorine or chlorine dioxide.

The rugged and reliable ECD PA80 Peracetic Analyzer features multiple PAA measurement ranges:  0-20, 0-200 and 0-2000 ppm.  Providing multiple measurement ranges allows plant engineers to select the monitoring range that best fits the requirements of their product batch recipes, their processes and equipment cleaning requirements.

The food and beverage, medical and pharmaceutical industries all rely on PAA as a cleaner and sanitizer of process equipment, medical instruments and for bottle washing. It is also used as a disinfectant in municipal wastewater treatment and industrial cooling towers.

PAA is a highly effective bactericide that does not form any harmful disinfection by products (DBP) like many chlorine products do. It decomposes naturally into acetic acid and water and does not form a residual that has to be removed from the treated water. 

The PA80’s plumb and play design incorporates a constant head flow control device, a pH sensor, a peracetic acid sensor and ECD’s T80 analyzer/ transmitter—all conveniently mounted on a PVC panel.  Plant technicians simply connect the sample and drain lines, connect the power and outputs, and the PA80 is ready to use. Calibration is accomplished by a grab sample comparison.

The PA80 Analyzer’s transmitter is 110-240 VAC or 24 VDC powered and allows either parameter to be graphically displayed with user defined line, bar or gauge style graphs. The standard configuration has two 4-20 mA outputs, three alarm relays and an industry standard MODBUS RTU (remote terminal unit).

Relying on precision amperometric PAA sensors that are flow sensitive, the PA80 provides accurate measurement with a minimum flow rate past the sensor of 0.5 ft/sec; above this flow rate the output is virtually flow independent. The PA80’s constant head flow control device (CFD) maintains the optimum flow past the sensor over a wide range of incoming sample flow rates. The minimum flow required for the CFD is 10 gal/hr, and the maximum flow rate is 80 gal/hr with the sample draining at atmospheric pressure.

To reduce maintenance technician time and costs, the PA80 features an optional auto clean configuration, which includes a solenoid actuated spray cleaner that uses either 30 psi process water or air. An easily adjusted timer controls the period and duration of the cleaning cycle.  The optional spray cleaner also eliminates fouling to protect batch sensitive products and prevent process line downtime.

Inductive Conductivity Analyzer

Inductive Conductivity Sensors – Model S80 IC

S80 Inductive Conductivity Sensors

The measurement of electrolytic conductivity is used to determine the amount of dissolved ionized material in a solution. It is most commonly made by measuring the electrical conductivity between two metallic electrodes placed into the solution. Inductive Conductivity is a non-contacting conductivity measurement made between two toroidal magnetic coils located inside a sensor that are inductively coupled through the solution’s conductivity. Since the toroidal coils are located inside the sensor’s PVDF (polyvinylidene fluoride) body, the inductive sensors are ideal for applications where corrosion or coating of the metallic electrodes will occur.  Inductive sensors excel in the higher conductivity ranges and in applications where coating is a problem. The chemically resistant PVDF (KYNAR) body is excellent for corrosive environments. These sensors are ideal for measuring high conductivity solutions and % concentration measurements. The measurement range of the inductive sensor is from 50 µS to 1000 mS. The Model S80 Inductive Conductivity sensors have the same ¾” diameter body as the rest of the S80 sensors. A wide array of installation methods are available, insertion into a pipe with a compression fitting or a valve retractable design for entry and removal into a pipe without shutting off the flow. Immersion into tanks or channels with a stand pipe and various flow cells are also available.

S80 sensors are a family of digital sensors designed for use with ECD digital analyzers, the Model T80 and X80 transmitters. The S80 sensors convert the analog signals into a temperature compensated digital protocol that allows two way communications with the transmitter. The type of sensor, identity and serial number are stored in the sensor’s memory along with three calibration registers. When connected to an ECD digital analyzer the sensor’s identity and calibration information are uploaded to the analyzer which configures the displays and outputs to the values appropriate to the sensor’s measured parameter.

trace dissolved oxygen sensor

DO90 – Trace Dissolved Oxygen Analyzer

Prevent Industrial Boiler Corrosion & Scale With

Continuous Trace DO2 Analyzer Accurate to ppb Levels

Ideal For Electric Power Generation Steam Turbine Systems

Irvine, CA—June xx, 2015—Process and plant engineers who need to improve boiler efficiency, reduce maintenance and lower costs will find the new plug-n-play rack mount DO90 Trace DO2 Analyzer from Electro Chemical Devices (ECD) provides continuous precision measurement and alarming of trace dissolved oxygen (DO2) levels in boiler feed water supporting electric power generation steam turbine systems.

Oxygen should only be present in trace quantities in boiler feed water for steam turbine systems because excessive concentrations of oxygen can result in corrosion damage to the components of the boiler’s steam cycle.  Oxygen in the feed water of high-pressure boilers attacks the boiler’s metal construction, leading to severe pitting. In addition, the iron oxide produced by the corrosion leaves iron deposits requiring additional system maintenance.

To remove the oxygen, the boiler feed water is pretreated by thermally or chemically degassing it to achieve oxygen-free water. This state must be maintained throughout the steam cycle. De-aeration is accomplished through the use of physical mediums, including de-aerating heaters or chemical mediums like oxygen scavengers.

Processes that rely only on periodic grab samples to monitor the ppb oxygen concentration in boiler feed water introduce the risk of significant sampling errors.  Such sampling errors can eventually lead to the use of additional costly water treatment consumables and more frequent boiler maintenance cycles that can shorten boiler life.

To prevent these problems, the ECD Model DO90 Trace DO2 Analyzer features a lead silver, galvanic, dissolved oxygen sensor with a durable PFA Teflon® membrane.  The sensor is combined with an intelligent universal transmitter designed for continuous service. The sensor is housed in a rugged, 316L flanged stainless steel body for use in rugged industrial process environments.

Oxygen diffusing through the DO90 sensor’s membrane is reduced at the cathode, producing hydroxide ions that react with the lead ions in the electrolyte to form lead hydroxide.  The anode dissolves more lead ions into the electrolyte, sending electrons to the cathode to reduce any oxygen present. The current flows from the lead anode to the cathode. Under constant conditions, the current is proportional to the oxygen concentration of the medium.

The Model DO90 sensor is a smart, digital device featuring a noise-free digital signal for easy communication.  All data processing is internal to the sensor, and the calibration information is stored in the sensor’s memory.  It also provides integral temperature measurement.

The DO90 sensor features an easily replaceable electrode cartridge, which eliminates the need for messy electrolyte/membrane replacement kits. It offers users a wide measurement range of 0.001 to 20.00 mg/l or ppm/ppb auto-ranging. It operates at a process temperature range of –5 to 50°C and a process pressure range of 0 to 15 psi maximum overpressure. Vacuum operation is not permitted. Highly stable over time, the DO90, with its continuous polarization, drifts less than 1% per month.

The Model DO90 sensor is compatible with ECD’s T80 Universal Transmitter.  It is a single or dual channel transmitter designed for the continuous measurement of pH, ORP, pION, dissolved oxygen, turbidity, conductivity or resistivity in a general purpose industrial environment. The transmitter digitally communicates with the Model DO90 sensor or any ECD Model S80 intelligent sensor, automatically configuring the transmitter’s menus and display screens to the measured parameter.

Irvine, CA – May 19, 2015—Aquaculture operators in search of a better way to automate testing for dissolved oxygen (DO), pH, nitrate and other parameters will find the modular plug-n-play T80-S80 Analyzer System from Electro-Chemical Devices (ECD) simplifies operations and lowers total operating costs.

In Aquaculture, the reliable detection of rising levels of DO, pH, nitrates and other parameters is essential to keep fish healthy. These parameters can reach toxic levels quickly or facilitate conditions that lead to disease affecting the health of fish, which requires additional treatments or can cause the death of the fish.

While many operators rely on portable sensors, they require staff time to manually complete the testing on a fixed schedule that can be hard to maintain consistently during their busy work day. The challenge and expense of dedicating staff time to testing becomes incrementally problematic in larger or remote operations.

The installation of fixed analyzer systems, however, such as the rack-mount ECD T80 Universal Transmitter with S80 Intelligent Sensors automates the measurement process. The T80-S80 Analyzer System can be seamlessly integrated with popular control system communication protocols to provide a closed-loop water monitoring and treatment system that maintains water quality for optimum fish growing conditions.

The T80 Transmitter’s own highly intelligent digital protocol simplifies installation set-up and process measurements while also reducing maintenance costs. The two-channel model offers membrane switch navigation, a simple menu structure and soft key menu choices with an easy-to-read 2 ¾ -x- 1 ½ inch LCD display.

The T80 accepts any S80 intelligent sensor or any standard pH sensor with solution ground using the optional T80 input card as an input. It is available with 4-20 mA output with MODBUS RTU on 24 Vdc and 110/220 Vac instruments. The T80 can be configured with optional HART® 7 communication protocol and an optional three alarm relay.

The T80 Transmitter digitally communications with any S80 Sensor, automatically uploading the sensor’s calibration data and configuring the transmitter’s menus and display screens to the desired parameter. S80 Sensors feature a choice of two universal sensor designs: Insertion/Submersion or Valve Retractable with flared end to prevent blow out. They have a rugged ¾-inch OD 316 stainless steel body with a 10-foot cable or an optional waterproof detachable cable assembly.

The versatile S80 DO Sensor features a measurement range from 0.00-20.00 ppm (mg/l) over a temperature range from -10° to 60°C. For pH, the S80 features a measurement range from 0.00 -14.00 pH with a temperature range of -10° to 90°C. To monitor nitrates, the S80 Sensor has a measurement range of 0.1 ppm to 14,000 ppm (3-11 pH), 7×106 molar to 1 molar NO3 over a temperature range from 0° to 40°C.

With the S80 Sensors, the economical auto clean option 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 auto clean option pays for itself by reducing time consuming manual maintenance routines, which frees staff for other more productive activities.

Combining ease of set-up, modular design and low maintenance, the T80-S80 Analyzer System is ideal for demanding aquaculture applications. From single point of measurement to monitoring multiple parameters, the flexible T80-S80 Analyzer System is an economical automation tool for economical aquaculture production operations.

Reagentless Total Chlorine Analyzer - TC80

Plug-n-Play TC80 Total Chlorine Analyzer Simplifies Monitoring and Lowers Cost

Irvine, CA—March 17, 2015—Industrial process and municipal engineers will want to learn more about the new plug-n-play TC80 Total Chlorine Analyzer from Electro-Chemical Devices (ECD), offering simplified water monitoring and treatment processes, easy installation and less maintenance for lower ownership costs.

Highly reliable, the TC80 Analyzer 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. Its plug-n-play design installs quickly right out of the box.  The TC80’s advanced panel mount design includes built-in flow control, which eliminates the need for complicated pressure regulators and rotometers.  Built-in automatic pH compensation also eliminates the need for expensive reagents to reduce maintenance and life-cycle costs.

            The TC80 features a panel mount design that incorporates a constant head flow control device, a pH sensor, a chlorine sensor and ECD’s T80 analyzer/transmitter conveniently mounted on a PVC panel. Connect the sample and drain lines, next connect the power and outputs, and the TC80 is ready to use. The TC80 is calibrated at the factory before shipment. Calibration is accomplished by DPD comparison.

Total chlorine is defined as the amount of free chlorine and combined chlorine in a water sample. Combined chlorine includes chloramines and any organic or bound chlorine compounds. The TCA Sensor is a three electrode amperometric sensor with a gold cathode, silver halide anode and 304 SS counter electrode. The TC80’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 0.5ft/sec, 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/hr, and the maximum flow rate is 80 gal/hr with the sample going to drain at atmospheric pressure.

The TC80 Analyzer is available with either 110-240 VAC or 24 VDC power. The TC80 graphically displays both the Total Chlorine and pH allowing for easy trend analysis. The standard configuration has two 4-20 mA outputs and three alarm relays.

ECD DC80 De-Chlorination Analyzer

New ECD DC80 De-Chlorination Analyzer Measures Near Zero Levels of Chlorine for Repeatable Accuracy

Ideal for De-Chlorination Applications Including Municipal Water Systems and Industrial Cooling Water
Irvine, CA—January 26, 2015—Municipal water system and industrial process engineers in search of an analyzer that accurately measures near zero levels of chlorine will want to learn more about the plug-n-play DC80 De-Chlorination Analyzer from Electro-Chemical Devices (ECD), which utilizes a zero-shift method to ensure stable and reliable chlorine measurement.

Conventional amperometric chlorine sensors are unstable when measuring near zero amounts of chlorine, which can lead to inaccurate and inconsistent readings. The DC80 De-Chlorination Analyzer utilizes a “zero-shift” methodology to provide accurate measurement and to protect total chlorine sensors from damage, which naturally occurs when the water samples measured contains near zero or zero levels of chlorine.

For example in wastewater treatment when monitoring for chlorine just before outfall, there can be no chlorine present and yet measurement is still necessary. If there is no chlorine present then the electrode becomes unstable and finally unresponsive. Therefore the very process of measuring de-chlorination becomes problematic. If 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

The DC80 De-Chlorination Analyzer solves this problem: It is a total chlorine analyzer that uses the “zero shift” strategy to monitor near zero amounts of total chlorine. Chlorine is metered into the sample shifting the zero from a near zero chlorine concentration to a measurable value. The analyzer’s offset feature allows the metered value to be subtracted from the measurement.

The DC-80 De-Chlorination Analyzer monitors chlorine in drinking water, wastewater, cooling water and other de-chlorination applications from 0.05 – 20 ppm.

Self Cleaning Nitrate Analyzer System

Self-Cleaning HYDRA Nitrate Analyzer System For Water Quality

Sensor Spray Cleaner Ensures Measurement Accuracy In Dirty Environments

Offering a precision nitrate ISE electrode sensor with an integral self-cleaning sprayer, the new HYDRA Nitrate Analyzer System from Electro-Chemical Devices, Inc. (ECD), is ideal for nitrate monitoring in wastewater treatment aeration basins.

The HYDRA Nitrate Analyzer System monitors the nitrification process in aeration basins at wastewater treatment plants, a process during which toxic ammonium ions are oxidized into much less toxic nitrate ions 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 NO3N measurement helps optimize the methanol being fed to the digester, minimizing cost, and also to provide a trend indication of the total nitrogen (TN) in the effluent.

The intelligent HYDRA Nitrate Analyzer System measures the concentration of dissolved nitrate as nitrogen (NO3N) in water. The sensor uses two electrodes to determine the NO3N concentration: a nitrate ion electrode and a chloride ion electrode. An optional electrode is also available for pH or ammonium measurement.

The nitrate ion electrode provides the primary measurement. A second electrode measures the Chloride ions in the sample which interfere with the nitrate electrode. The HYDRA Analyzer subtracts the appropriate amount of signal from the nitrate measurement for accurate monitoring. The sensor also detects temperature, and the analyzer provides a temperature-compensation calculation for accurate measurement.

The rugged ECD HYDRA Analyzer nitrate sensor offers 1.25-inch NPT rear facing threads for attaching an extension/immersion tube for easy installation from catwalks or handrails. Internal signal conditioning allows the sensor to be mounted up to 200 meters from the analyzer. The sensor is extremely low-maintenance, featuring a movable electrode guard to facilitate easy electrode replacement when necessary.

Adding the optional AC10 Automatic Sensor Cleaner decreases HYDRA Analyzer sensor maintenance cycles and helps maintain sensor measurement accuracy in turbid water conditions by preventing the buildup of biofilms and other soft coatings. The AC10 cuts plant operating costs by reducing manual cleaning time and the amount of chemicals used for unnecessary water treatments performed due to inaccurate sensor readings caused by films and coatings that develop over time.

The AC10 can be used as either a Single Channel or Dual Channel System with the HYDRA Nitrate sensor. Combined with a Sensor Spray Head and a C22 Analyzer/Controller, it uses pressurized air to generate an area of high turbulence in the water surrounding the measurement end of the sensor.

The system’s HYDRA Analyzer is configured to periodically actuate a cleaning cycle using the integral spray cleaner in the nitrate sensor, minimizing the formation of biofilms or other coatings on the electrodes and keeping maintenance to a minimum. The cleaning cycles feature a user configurable period and duration. During the cleaning cycle the 4-20 mA output is held at either a preset value or the last value.

The AC10 Air Blast Spray Cleaner features a highly reliable high current contactor that assures years of trouble free service. It is available with either a 115 VAC 3.0 Amp or 220 VAC 1.3 Amp Air Compressor, housed in a rugged, corrosion resistant, fiberglass reinforced polyester enclosure.

All-In-One Sulfide Analyzer Helps Control Odor, Protects Equipment and Cuts Maintenance Cost

Ideal for Municipal Water Treatment, Wastewater Plants, Oil/Gas Refineries, Chemical Plants, Paper/Pulp and Tanneries

With its breakthrough all-in-one design the new
SMS-22 Sulfide Ion Measurement System from Electro-Chemical Devices, Inc., (ECD) can be quickly installed with no special tools, features user-selectable automated sequential sampling of sulfide ions in water and lowers plant technician and supply maintenance costs.

Hydrogen sulfide (H2S) is a gas that dissolves in water and gives it a “rotten egg” odor. H2S is present in well water, municipal wastewater and wastewater produced by refineries, tanneries, chemical plants, and paper and pulp facilities. It is typically formed in environments prone to the creation of septic conditions. In addition to odors, excessive concentrations of H2S in wastewater can lead to corrosion and structural damage to municipal water/waste infrastructure including equipment and piping.

The SMS-22 Sulfide Measurement System saves time and labor costs for municipal water operations by completing all the necessary steps to measure sulfide ions in a water sample. Because sulfide ions only exist at high pH values, this is a multi-step process. The SMS-22 conditions the sample, measures the sulfide, neutralizes the sample, measures the pH and drains and rinses the cell. After measurement, the highly caustic sample pH is reduced to a safe level near pH 8.

The ECD SMS-22 is a sequential sampling analyzer. Featuring automated sequential sampling, the Model C-22 Analyzer controls the sequential sampling with a combination of relays and timers. Sampling times are easily adjustable from 2 samples per hour to 10 samples per hour, and this economical system offers very low reagent consumption.

The SMS-22 Sulfide Ion Measurement System uses a sulfide ion selective electrode (ISE) to measure the total amount of sulfide present in the sample. ISE-based S-2 measurement provides a wide measurement ranges of 0 to 5 ppm and up to 500 ppm using economical, easily replaceable electrode cartridges. It features a measuring temperature range of -5 to 50°C (20° to 120°F), accuracy to ±20 ppb or 5 percent of reading, whichever is greater, and repeatability of ±2 percent of reading.

Easy to install and maintain, the SMS-22 features 4-20 mA outputs that display the total sulfide as well as the neutralized pH value. The output values are captured in the measurement cycle and displayed until the next measurement cycle. The rugged enclosure provides IP66 protection and is rated NEMA 4X. The base is made of gray hot-molded fiberglass-reinforced polyester and the cover is made of transparent polycarbonate with non-metallic hinges.
