HYDRAcap™ ultrafilitration modules

Our solution to treat surface water, ground water, seawater and wastewaters as either primary treatment or as pretreatment to reverse osmosis (RO) and nanofiltration (NF)

  • Low pressure
  • Chlorine resistant
  • Low fouling
  • 5 log removal
Compared to conventional pretreatment, HYDRAcap™ allows for 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.
Operation
The filtration mode of HYDRAcap™ modules is inside-out: feed water flows from the inside of the fibers to the outside. For backwashing, filtrate is forced through the fibers in reverse flow, from the outside to the inside, such that accumulated solids are removed from the fibers.
Benefits
Our HYDRAcap™ is a low fouling hydrophilic polyethersulfone membrane, tolerant to chlorine, peroxide and other oxidants resistant to pH extremes. It exhibits 5 log (99.999%) removal for bacteria, giardia, cryptosporidium and 4 log removal for viruses. Turbidity is reduced to <0.07 NTU and HYDRAcap’s benefit from low pressure operation, either in dead-end mode or cross flow.
