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.

The versatile TC80 Analyzer eliminates consumables, simplifies installation and reduces maintenance with a self-cleaning design to lower the total cost of instrument ownership over its long life. This reliable analyzer is a panel-mounted unit that is ready-to-use right out of the box. It is also fully compliant with the U.S. Environmental Protection Agency’s (EPA) Method 334.0.

The TC80 Cl 2 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 Cl 2 from 0.05 to 20 ppm or (2) a standard low-range configuration of 0.005 to 2.000 ppm. This analyzer comes factory pre-calibrated to the chosen measurement range before shipment, which also 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 Cl 2 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.

The TC80 Cl 2 Analyzer is a complete solution requiring no additional third-party components. Everything needed comes in one box from ECD 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.

There is no special technician training or tools required for installing the TC80 Cl 2 Analyzer. Technicians simply connect the sample and drain lines, connect the power and outputs and the
analyzer is ready to use. The analyzer’s amperometric sensor technology and automatic pH compensation keep the cost of ownership low by requiring no inventory of expensive reagents on a shelf, tracking/ordering of reagents or valuable technician labor time to replace them.

With its automatic flow control and large flow tubes and cells, the TC80 Analyzer greatly reduces clogs and blockages, which are a common problem in other total chlorine analyzers and allows for easy cleaning. It also can be ordered with an auto cleaning option to keep the chlorine sensor clean from water contaminants for an extended period of time. This useful time scheduled pressure-spray washer keeps particles from adhering and building up on the sensor.

For user installation flexibility, the TC80 Cl 2 Analyzer is available with either 110-240 VAC or 24 VDC power. The TC80 graphically displays both the total chlorine and pH levels, which supports
easy trend analysis. The standard configuration has two 4-20 mA outputs and three alarm relays, 24 VDC or 110/220 AC power.

Users will appreciate the choice of MODBUS and/or HART communication that is available when ordering. Both digital bus communication options report Cl 2 analysis data directly to automated process control systems that can adjust Cl 2 levels in the process stream according to real-time conditions.

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.

With an intuitive, easy-to-use touch-screen display, the CA6 Analyzer displays 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 CA-6 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).

Anaheim, CA—December 14, 2022—Engineers responsible for protecting water systems from oil contamination will find the highly accurate, reliable OIW80 Oil In Water Analyzer from Electro-Chemical Devices (ECD) helps them meet environmental regulations by detecting oily water contamination quickly and accurately to prevent damage to drinking water and sensitive ecosystems, as well as plant emergency shutdowns, product batch fouling losses, costly unplanned maintenance, state/federal regulatory corrective actions and expensive fines.

Oil in water is a serious issue for the petrochemical and many other process industries. Large industrial plant fuel pipe leaks, broken valve spills, storage tank ruptures, etc., all can lead to contamination incidents, which can affect surface water from streams, rivers or lakes, as well as ground water and water storage systems such as municipal reservoirs and water storage tanks.
Beyond petrochemical plants, other common major industries vulnerable to oil-in-water contamination include: electric power, food/beverage, electronics, pharmaceuticals and more. Oil-in-water leaks can quickly affect plant water re-use systems and effluent treatment prior to discharge at a wide range of facilities including airports, harbors, large university or corporate campuses, convention centers—anywhere paved surfaces support transportation systems.

The highly intelligent, precision OIW80 Oil in Water Analyzer reliably measures oil over a wide range of 0 to 30 ppm (mg/L), and it can be factory preconfigured to measure oil in multiple ranges or easily set in the field. This rugged, high-performance analyzer’s responsive sensor operates over a broad temperature range from 41 to 113oF (5 to 45oC) to quickly detect leaks and alert plant technicians.

OIW80 Oil In Water Analyzer

Designed for demanding and/or dirty plant environments, the highly dependable OIW80 Oil in Water Analyzer’s rugged sensor features a built-in wiper cleaning system to remove bio solids and films that might cloud the sensor window’s visibility. The sensor features a built-in automatic screen window wiper, which reduces technician manual checks and the frequency of scheduled maintenance cleanings.

The heavy-duty construction of the OIW80 sensor’s rugged housing utilizes strong, corrosion resistant Stainless Steel (standard) or optional Titanium and meets the IP68 water ingress standard. Every aspect of the sensor’s design has been tailored for years of reliable operation and trouble-free service in the demanding wet environments typical of industrial and municipal water and wastewater treatment applications.

The rugged, dependable OIW80 sensor utilizes state-of-the-art Fluorescence sensing technology for precision measurement of oil in water, which is typically proportional to its concentration. The sensor communicates directly with ECD’s versatile T80 Universal Transmitter when oil is detected.

During installation, the OIW80 System is connected to the intelligent ECD T80 Transmitter and the sensor’s calibration range information is automatically uploaded to the analyzer. It then automatically configures the displays and outputs of the transmitter to the values appropriate to the oil sensor’s measurement parameters.

The T80 Transmitters are available as either single channel or dual channel devices, allowing one analyzer to measure up to two parameters or two ranges. This transmitter is available in a 24 VDC or a 100/240 VAC power configuration. All versions are available with an optional HART® output to support integration with larger control systems.
