Cleaning methods and advantages of ultrafiltration membrane

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.

Can ultrafiltration membrane be filtered with high temperature water? How to clean ultrafiltration membrane 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.

Main characteristics and precautions of roll type ultrafiltration membrane

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.

Characteristics and application range of reverse osmosis membrane equipment

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.

How to judge whether reverse osmosis membrane needs cleaning

The operation parameters after standardization are as follows: (the product tax flow rate decreases by 10%, the desalination rate decreases by 5%, and the feed water and concentration water pressure difference increases by 15%, which needs to be cleaned) the benchmark is the operation performance of the new membrane in the initial operation of 24-48 H. If the pretreatment design is reasonable and the operation is normal, it should be cleaned once every six months to a year. If cleaning is needed less than three months, the pretreatment method should be improved.

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. The reverse osmosis technology can effectively remove the dissolved salt, colloid, bacteria, virus, bacterial endotoxin and most organic matters and other impurities in water
