The Duratherm HWS Series includes RO, NF, and UF membrane elements. This Series is specifically designed to maximize the benefits of hot water sanitization for industries relying on chemical free sanitization for product quality and/or industry compliance standard.
Separation system sanitization protocol is performed via periodic exposure to temperature as high as 195°F (90°C) at minimum feed pressure to kill microorganisms by denaturation and coagulation of the proteins chains.
The Duratherm HWS RO and HWS NF are suitable for separation systems purifying water at temperature up to 122°F (50°C) in low crossflow environment and no suspended solids.
This Series includes a variety of size 8″, 4″ and 2.5″ diameters. All element constructions include Durasan* Cage outer wrap, Polysulfone ATD and central tube.
