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 from Electro-Chemical Devices (ECD), which automates routine alkalinity measurement with a more cost-effective approach, states the company.

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 the company’s sophisticated 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 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 the Analyzer is especially important for the effective treatment of both municipal drinking water and wastewater, where it can affect the wastewater anaerobic digestion process, adds the firm. 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 Analyzer simplifies and automates alkalinity measurement. Technicians can easily install and start up the 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, mentions the company. Wall mounting hardware comes standard with each analyzer, but an optional bench top stand with reagent holder is also available.

The 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 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, concludes the firm.
