HYDRAcap is used to treat surface water, ground water, seawater and waste water as either primary treatment or as pretreament to reverse osmosis (RO) and nanofiltration (NF). Compared to conventional pretreatment, HYDRAcap allows higher fluxes for RO and NF systems while maintaining longer intervals between cleanings. In some cases it replaces conventional pretreatment for potable applications, ground water recharging and water recycling.

The 0.8 mm HYDRAcap is used for surface water applications containing lower turbidities. The 1.2 mm HYDRAcapLD offers a 50% larger capillary diameter for a wider range of high fouling applications.

HYDRAcap enhances RO and NF element system design and operating conditions when used as a pretreatment step for desalination, treatment of surface waters and municipal and industrial effluents.
