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).
The HFW1000 modules are operated vertically. The modules are operated with crossflow (feed- and-bleed).
