Ultra filtration membrane AQU-250A
Ultrafiltration (UF) filtrates in the 0.01-micron range. The element comprises of hollow fibers of membrane material. UF is a type of membrane filtration in which hydrostatic pressure forces a liquid against a semipermeable membrane. It does not differ fundamentally from reverse osmosis, microfiltration or nanofiltration, except in terms of the size of the molecules it retains. UF can be used as pretreatment for reverse osmosis systems or as a final filtration stage for deionized water. It is an excellent purification method in areas where the TDS is low or in drought-stricken areas, as it produces no waste.
Ultrafiltration is very effective at removing tiny particles which can quickly foul reverse osmosis membranes, thus reducing the silt density index of the water. For this reason, it frequently serves as pretreatment for surface water, seawater, and biologically treated municipal water upstream of RO.
UF is also used in industry to separate suspended solids from solution. Industrial applications include power generation, food and beverage processing, pharmaceutical production, biotechnology, and semiconductor manufacturing.
