This paper describes the 10 months pilot trial on a full-size Hollow fiber Nanofiltration membrane (HFNF) module of type HFW1000. During this pilot continuous high removal rates of Natural Organic Matter ( NOM) > 80%, Color > 90% and COD > 75% were established. A virus removal of 99.9% was obtained. Water municipalities are orientating on HFNF to replace other treatment technologies Using HFNF membranes has multiple advantages over conventional spiral wound NF membranes. They are back-washable, chlorine resistant and offer a >Log 6 removal on bacteria and a > Log 4 removal on viruses.
