  • Influence of permeation on air/water cleaning of spiral wound membrane NF/RO elements

    To improve hydraulic conditions, periodic air/water cleaning (AWC) is applied to a nanofiltration (NF) spiral wound membrane (SWM) element under permeation conditions to control biofouling and particulate fouling. A pilot study was carried out for 212 days with a vertically positioned SWM element fed by tap water enriched with a biodegradable compound (60 μg acetate-C l−1). Operational parameters ...
