Protecting Surface & Tank Water Storage Systems

With Intelligent Dissolved Oxygen (DO) Analyzer

 Ideal for Maintaining Healthy Municipal Water Storage Systems, Lakes,

Streams, Ponds, Fisheries & Hatcheries and Aquatic Plant Life

Anaheim, CA—February 21, 2024—Municipal water systems engineers concerned about protecting large surface and tanks water storage systems, will want to consider how the advanced S80-T80 Dissolved Oxygen Analyzer from Electro-Chemical Devices (ECD) helps them easily, accurately and economically measure dissolved oxygen (DO) levels to ensure they protect municipal water supply storage systems as well as protect sensitive ecosystems

Oxygen is naturally present in bodies of water and its levels are measured as dissolved oxygen (DO). These water resources receive their oxygen from the atmosphere and from aquatic plants. Running water, such as that of a swift moving stream, dissolves more oxygen than the still water of a large pond or lake. All aquatic animals such as fish, including those farmed for human consumption, need adequate levels of DO to breathe, feed and thrive.

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

The U.S. Environmental Protection Agency (EPA) warns that low levels of oxygen (hypoxia) or no oxygen levels (anoxia) can occur when excess organic materials, such as large algal blooms, are decomposed by microorganisms. During this decomposition process, DO in the water is consumed.  Knowing DO levels allows technicians to remediate issues early on in vital surface water systems with dual use, such as those for both consumption and recreation.

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

ECD DO Analyzers Protect Water Quality                                                 

animals might move away, decline in health or even die, contributing to the decline of important natural resource ecosystems.

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

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

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

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

Measuring Alkalinity With CA900 Analyzer Optimizes Water Piping Corrosion Prevention Systems

Helps Extend Municipal Water Piping Life and Enhance Water Quality

Anaheim, CA—October, 23, 2023—Municipal water engineers tasked with preventing pipe corrosion by carefully balancing system pH/Alkalinity/DIC levels will find that the advanced CA900 Alkalinity Analyzer from Electro-Chemical Devices (ECD) automates routine alkalinity measurement with a highly cost-effective approach.

One of the U.S. EPA approved methods of preventing corrosion in piping requires the understanding and balancing of the proper relationship between pH, alkalinity and DIC levels. Otherwise, toxic lead and copper contaminants can be accidentally released into the water system, which corrodes piping and contaminates the drinking water.

Alkalinity is a measure of the capacity of water to neutralize acids (pH). Alkaline compounds such as bicarbonates, carbonates and hydroxides remove hydrogen (H₂) ions and lower the acidity of the water to prevent pipe corrosion. 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.

ECD’s sophisticated CA900 Analyzer is designed with sophisticated titration technology that is used to calculate 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.

Typically, the CA900 Alkalinity Analyzer performs a single measurement per analysis cycle.  Its program sequence consists of a cleaning cycle, sample acquisition, monitoring of pH, adding 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.

Alkalinity Measurement with CA900 Analyzer 

Measuring alkalinity levels with ECD’s CA900 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 intelligent CA900 Alkalinity Analyzer from ECD simplifies and automates measurement. Technicians can easily install and start up the CA900 Analyzer in less than 15 minutes with no special tools or 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 is standard with each analyzer, but an optional bench top stand with reagent holder also is available.

ECD’s CA900 Alkalinity 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.

Anaheim, CA—July 25, 2023—Oil and gas engineers tasked with accurately measuring hydrogen sulfide (H₂S) levels in both production and refining operations will want to know more about the all-in-one CA900 Sulfide Analyzer from Electro-Chemical Devices (ECD).

The ECD CA900 Sulfide Analyzer is an all in one analyzer for the continuous measurement of sulfide ions in aqueous media, which are typically encountered at drilling production sites and in refinery operations, as well as in chemical plants.  Other applications include municipal drinking water and wastewater effluent treatment, pulp/paper plants and tanneries.

Featuring minimal reagent consumption, the CA900 Sulfide Analyzer requires less than two gallons per month providing two samples per hour, or lasting five months at two samples per hour. Users save on reagent cost and disposal fees while also minimizing technician labor time.

Hydrogen sulfide gas dissolves in water and gives it that “rotten egg” odor. It exists in acidic water as a dissolved gas, at values above pH 7. Bisulfide ions (HS) are the predominant form of sulfide and are only present at very high pH values (above pH 13), which is where sulfide ions (S^-2) are present and measurable.

The ECD CA900 uses an advanced, reliable sulfide ion selective electrode (ISE) sensing technology to measure the total amount of sulfide present in the sample. This measurement must be made at the high pH levels where S^-2 is present.   In order to achieve this high level of S^-2, potassium .hydroxide (KOH) is added to raise the sample level to around pH 13 (a pH electrode measures the actual pH level).

Sulfide and bisulfide co-exist in a pH dependent equilibrium with the ratio of each dependent on the pH. The sulfide ISE sensor measures the sulfide present in the sample and the pH measurement infers what percentage of the total sulfide is present. The analyzer then calculates and displays the total sulfide present.

The highly caustic sample is then neutralized with HCl, and the pH is measured and displayed to verify the neutralization. The neutralization of KOH is accomplished with HCl and produces potassium chloride (KCl) salt and water. The neutralized sample can be disposed of as waste or returned to the water supply.

ECD’s CA900 S^-2 Analyzer measures S^-2 over a wide range from: 0.02 to 500 mg/l (0.02 to 500 ppm) over a temperature range of 20 to1 20°F (-5 to 50°C). The sample cycle rate is user changeable with a minimum cycle rate of 6 minutes per cycle time.  The analyzer’s full-featured design also comes with four 4-20 analog outputs and four configurable relays (SPDT 15A 250VAC).

The CA900 S^-2 Analyzer is easy to start up and maintain. First connect the sample feed line, reagent lines and drain line to the analyzer. Mount the S^-2 and pH sensors in the flow cell. Next connect the two outputs (S^-2 and pH) and supply power, a switched 110/220 VAC line. Prime the peristaltic pumps and start the measurement cycle.

With a touch screen display and 4-20 mA outputs, the S^-2 Analyzer will indicate the total sulfide and the neutralized pH value. A digital display indicates the S^-2 measurement and the 4-20 mA output values are captured in the measurement cycle and displayed until the next measurement cycle

Accessing information or customizing analysis routines are both easily accomplished with the CA900 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 in-plant monitoring and interfacing with personal handheld devices such as controllers, mobile phones, tablets, laptops and computers.

Anaheim, CA—June 21, 2023—Engineers responsible for industrial rinse water, cooling or chillier water, plant water re-use and environmental effluent treatment applications will find that the TC80 Total Chlorine Analyzer from Electro-Chemical Devices (ECD) provides highly accurate and dependable liquid measurement of Chlorine (Cl 2 ) in plant water at a lower cost.
