HYDRAcap® Hydranautics Ultrafiltration Membranes

Superior Ultrafiltration

HYDRAcap is used to treat surface water, ground water, seawater and waste water as either primary treatment or as pre-treatment to reverse osmosis (RO) and Nano filtration (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 portable applications, ground water recharging and water recycling.

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

Advantages

Low fouling hydrophilic polyethersulfone membrane
Tolerant to chlorine, peroxide and other oxidants
Resistant to pH extremes
Exhibits 5 log (99.999%) removal for bacteria, giardia, cryptosporidium and 4 log removal for viruses, and reduces turbidity to <0.06 NTU
Operating flexibility, direct or cross-flow filtration
