The treatment combining ultrafiltration (UF), using submerged ZeeWeed system, and reverse osmosis (RO), brackish low-energy membranes, enables to produce a high-quality infiltration water, this leads sustainable management Since start-up, July 2002, different measures have been taken optimize membrane performance. Intermittent use air on UF system variable recovery RO reduced energy consumption per cubic metre produced. latter also resulted lower chemical as did pauses chloramination. backwash concentrate are discharged into canal, together with that is not reused. 2003, IWVA performed tests natura...
