Ultrafiltration membrane is the most popular sewage treatment equipment at present. Under the long time operation, the ultrafiltration membrane will gradually form gel layer and pollutant deposition layer. In order to ensure the service life of the ultrafiltration membrane, we need to clean it regularly.
Ultrafiltration membrane is widely used in industry and has become one of the new chemical unit operations. It is used in separation, concentration and purification of biological products, pharmaceutical products and food industry, as well as terminal treatment device in blood treatment, wastewater treatment and ultra pure water preparation. Can ultrafiltration membrane be filtered with high temperature water
The membrane separation elements were tested with water before leaving the factory, and were vacuum packaged in 20 ppm isothiazolinone protection solution. The molecular weight of the membrane is 1000-200000. The membrane can intercept macromolecular impurities (such as protein, pigment, polysaccharide, etc.) and pass through the target products; It can also intercept the target product and pass through the small molecular impurities (inorganic salt, small molecule pigment, monosaccharide, ash, etc.) and water, so as to replace the traditional purification process of activated carbon decolorization, resin impurity removal and crystal extraction, so as to achieve the purpose of decolorization, impurity removal and product classification.
Reverse osmosis is to use sufficient pressure to separate the solvent (usually water) in the solution through the reverse osmosis membrane (a kind of semi permeable membrane). The direction is opposite to the osmosis direction. Reverse osmosis method with higher osmotic pressure can be used to separate, purify and concentrate the solution.
