Ultrafiltration (UF) is a membrane filtration technology that uses fine porous membranes to remove impurities, bacteria, viruses and organic substances from water.
Ultrafiltration is a mechanical process that can filter water through selective permeability membranes. The pore diameters of these membranes are approximately 0.01 micron, which enables the retention of unwanted particles and impurities while allowing pure water to pass through. The size of the pores depends on the type and quality of water to be treated.
Ultrafiltration is often used as a pre-treatment for other water treatment processes, such as reverse osmosis or nanofiltration. It is also used for treating drinking water, wastewater, surface water, industrial process water, and seawater drinking water production.
The advantages of ultrafiltration are that it does not require the use of chemicals, can be applied to various types of water, and can effectively eliminate bacteria and viruses. However, it may require pre-treatment to remove suspended substances, and the membrane may be prone to fouling, which requires regular cleaning.
