Water filter cartridge HFW1000

for nanofiltrationpolyethersulfonefor general purposes

X-Flow’s HFW1000 is a chlorine-tolerant nanofiltration module widely used in the production of process and potable water. This innovative module combines the high chemical resistance of X-Flow membranes with hollow-fiber technology and the superior properties of spiral-wound nanofiltration in the retention of dissolved organic matter. Typical applications are the filtration of surface water and WWTP effluent for the removal of color components, such as humic or fulvic acids, often in combination with the X-Flow Color Removal Package (CRP). FEATURES Excellent removal of organic matter Absolute barrier to bacteria and viruses: > 4-log (99,99 percent) Chlorine-resistant nanofiltration due to hollow-fiber technology Hydrophilic membrane composed of (modified) polyethersulfone (high performance and superb antifouling behavior) Highly asymmetric/microporous structure MWCO: 1,000 Da (Dextrane) Typical permeate quality: SDI < 3 Turbidity 90% (Pt-Co) Minimal salt rejection to maintain salt balance Online integrity testing Backwashable, easy to flush Simple pretreatment
