Ultra Filtration

is used to treat surface water, ground water, seawater and waste water as either primary treatment or pretreament.

Ultra Filtration

Ultrafiltration (UF) is a pressure-driven purification process in which water and low molecular weight substances pass through a membrane while particles, colloids and macromolecules are rejected.

UF membranes typically have pore sizes in the range of 0.01 – 0.1 µm which contributes to a high removal capability of bacteria, viruses, colloids and silt, thereby producing high-quality water. UF membranes typically have a service life of three to seven years or longer, compared to reverse osmosis membranes. They are commercially available in hollow fiber, tubular, plate and frame, and spiral wound configurations.

Ultrafiltration elements are 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). It can remove colloids, suspended solids, bacteria and viruses.

 


UF Applications:

– Drinking Water.
– Process Water.
– Waste Water.
– Sea Water.

UF offers:
– High and consistent product quality measured by turbidity (NTU), silt density index (SDI) or log removal value (LRV).
– Tolerance to feed water quality upsets.
– No use of pretreatment chemicals (polymer, coagulant, pH adjustment) and associated costs for sludge disposal.
– Small footprint and less weight than media filters.

 

When used as a pre-treatment for reverse osmosis (RO), UF also helps reduce fouling of RO membranes, which can lead to:
– Reduced chemical cleaning frequency and consequently, lower operating costs and downtime.
– The potential to operate RO at higher flux, with fewer membranes and vessels – leading to lower capital cost for the RO system.
