The new DCA-23 Seawater Dechlorination Analyser from Electro-Chemical Devices (ECD) is a measurement solution that requires no chemicals to monitor seawater chlorine levels accurately in a wide range of industrial process and municipal water treatment applications. The DCA-23 is a single-purpose analyser that monitors chlorine in seawater from 0.0 to 2.00 ppm. It measures the pH, temperature and Total Residual Oxidant (TRO) of seawater and converts them into an equivalent ppm chlorine value, which is displayed to conform with existing conventions. It features a minimum detection limit (MDL) of 0.014 ppm and a limit of quantification (LOQ) of 0.044 ppm, making the DCA-23 Analyzer suitable for monitoring in environments with the most stringent dechlorination regulations. The DCA-23 features three sensors, pH, TRO and temperature. The pH sensor measures from 0-14 pH, the TRO sensor measures from ±1500 mV and the temperature sensor measures from 0-100°C.

Fine particle filter available in Europe and China
Dow Water & Process Solutions (DW&PS) has introduced the TEQUATIC PLUS fine particle filter to the China and European market in October and November respectively, one year after its launch in North America. The filter has been designed for applications for difficult, high-solids water, including industrial wastewater treatment and reuse, and is supported by a recently opened manufacturing facility in Menlo Park, Calif.
The filter combines the power of continuously cleaning, cross-flow filtration with centrifugal separation and solids collection into one device to meet the demands of extreme water environments. It can handle variable total suspended solids up to 10,000 mg/L without frequent filter changes – even in the presence of oil, according to the manufacturer.
