Types Of Membranes
- Oct 24, 2016 -

To intercept the raw water filter membrane particle size classification, membrane hole from the rough to be divided into micro-membrane filter (MF) and ultrafiltration (UF), Nano filtration (NF) and reverse osmosis (RO). MF membrane pore size 0.05um, or more than 1000 MW, to remove colloidal, macromolecular organic compound objects. NF membrane pore size for the molecular weight of 100~1000. It removes material between the UF and RO, to remove trihalomethanes, odor, color, pesticides, dissolved organic matter, such as Ca and Mg. RO particle diameter of dozens of molecular weight separation to remove salt and inorganic salts. RO RO water pressure 1~2 times more than the osmotic pressure. In addition to these four, there are gas permeable membrane and ion exchange membrane. MF, UF, NF and RO in pressure-driven solid-liquid separation. Ion exchange membrane with electric drive salt molecules apart, such as seawater desalination. Gas permeation membranes was studied by gas membrane can make ethanol concentration and desalination.

Ultrafiltration membranes, microfiltration membrane, nanofiltration, microfiltration membrane, hollow fiber ultrafiltration membrane, powered by the membrane filter. Ultrafiltration membrane the most widely used at present, membranes form, divided into volumes, plate-and-frame, tubular or hollow fiber membranes and so on.
