Feedwater to industrial systems often have been pretreated with chlorine to retard microbiological growth. This chlorine, however, can irreversibly damage many thin-film composite membranes or pipes. Protech water pretreatment chemicals is designed to remove free and combined chlorine from reverse osmosis (RO), ultrafiltration (UF) and process feedwaters.

In addition, filter-aid and pH control agents from Protech can increase pre-filtration efficiency and help improve productivity in membrane systems for worry-free RO feedwater. Protech’s solutions are suitable for direct membrane filtration processes (UF/MF), multi-media filters and clarifiers, and other mechanical separation systems.
