Ultrafiltration (UF) pure water treatment Jan 05, 2018

Ultrafiltration is a technique widely used for water purification, solution separation, concentration, and the acquisition of useful substances from wastewater, and the high and new technology of wastewater reuse.

The characteristic is the application process is brief, do not need heating, power saving, low pressure operation, the installation area is small.

Ultrafiltration (UF) water treatment principle: exceed filter is a kind of screen can be divided into principle of pressure as the driving force of membrane separation process and filtration precision within the scope of 0.005 to 0.01 mu m, can be useful to get rid of the particles in the water cushion layer, colloid, bacteria and organic polymer materials.

It can be widely used in the separation, concentration and purification of matter.

Ultrafiltration process without phase transformation, normal temperature operation, is particularly suitable for separation of heat sensitive material, and has excellent heat resistance, acid and alkali resistance and oxidation resistance function, can under 60 , for pH 2-11 under the condition of long time running.

Hollow fiber ultrafiltration membrane is one of the most mature methods in ultrafiltration.

The outer diameter of hollow fiber is 0.5-2.0mm, the inner diameter is 0.3-1.4mm, the wall of hollow fiber tube is full of micropores, and the pore diameter is expressed as the molecular weight of the material that can be trapped, and the molecular weight can reach several thousand to hundreds of thousands.

The original water is pressurized in the outer or inner cavity of the hollow fiber.

Ultrafiltration is the process of dynamic filtration. The trapped material can be reduced with the concentration, and it can operate continuously for a long period of time without blocking the appearance of the membrane.
