SCALE INHIBITOR

ENVY-AS series scale inhibitor is divided into two kinds of phosphate and phosphate free, which can be applied to the water quality of high salinity, high alkalinity, high silicon and high sulfate, which can greatly reduce the possibility of falling membrane performance in the membrane fouling, and can be used in the production of drinking water (Certified to ANSI/NSF standard 60).
