Enhancing thermal desalination with Antiscalants and Dispersants

Dow has introduced a series of water treatment polymers, aiming to prevent scaling or fouling on reverse osmosis (RO) membrane surfaces and hard water scale in industrial, commercial, institutional and public water systems.

The figure demonstrates the compatibility of inhibitor to brine containing high levels of calcium. The x-axis indicates concentration of Ca2+ in ppm while the y-axis indicates transmittance generated when an inhibitor precipitates to create a turbid solution. Somil Mehta, technical service and development manager at Dow Energy and Water Solutions, explained, “As filtered water is separated, the impurities from source water gets concentrated in remaining [
