What effect does membrane pollution have on the effect of water in medical purified water equipment?

purified water in the pharmaceutical industry is generally used as a solvent for the preparation of pharmaceutical preparations or test water, so its standards should be strictly in line with the relevant management norms of the pharmaceutical industry to ensure water safety and hygieneMedical purified water equipment can be based on different water sources, independent design, so that equipment technology to adapt to the quality of raw water, equipment water standards in line with the quality requirements of the industryall kinds of raw water contain a certain concentration of suspended and soluble substancesSuspended matter is mainly inorganic particulate matter, colloids and microorganisms, algae and other biological particlesDissolved substances are mainly soluble salts (e.gchlorides) and insoluble salts (e.gcarbonates, sulfates and silicates)During reverse osmosis, the volume of inlet water is decreasing and the concentration of suspended particles and solubility substances is increasingSuspended particles are deposited on the membrane, clogging the inflow channel and increasing frictional resistance (pressure drop)Insoluble salts will precipitate from the thick water, forming fouling on the membrane surface, reducing the flux of the RO membraneThis phenomenon of the formation of sedimentary layers on the membrane surface is called membrane pollution, the result of membrane pollution is the deterioration of system performanceCommon contaminantsare calcium carbonate scale, calcium sulfate scale, metal oxide scale, silicon deposits, and organic or biological sedimentsThe nature of pollutants and the speed of pollution is related to water supplies, pollution is slowly developing, if not taken early measures, pollution will damage the performance of membrane components in a relatively short period of timeNanjing Tianshui small editor believes that for reverse osmosis membrane pollution the sooner the better, can be treated before causing damage, extend the service life of the reverse osmosis membrane, but also to ensure the production of normal water.
