Integrated Ultrafiltration IM-UF™ Systems

In Ultrafiltration untreated water is forced against a semipermeable membrane. The membrane allows the water molecules to pass through and screens out the colloids. Excess water is used to wash the colloids off the surface and to a drain. Ultrafiltration (UF) is a pressure-driven membrane separation process with the membrane pore size in the range of 0.001-0.01μm. Ultrafiltration system often contains hollow fine fiber ultrafiltration membrane devices for removal of suspended solids, colloidal material, macromolecule substances (protein, nucleic acid, and polysaccharide), bacteria and organic matters from water so as to make the water suitable for reverse osmosis. Ultrafiltration is an ideal method for producing drinking water from surface water. Surface water contains microbial as well as suspended solids. Combination UF and RO can treat secondary effluent from sewage treatment plant for use in ground water recharge or creation of a barrier to minimize seawater intrusion in the aquifer. (PAT UF membrane technology can provide a reliable treatment system that eliminates the need for multiple treatment steps).
