Application of ultrafiltration technology
As a membrane separation technology, ultrafiltration has been widely used in various fields of the national economy such as industrial production, medicine and health, environmental protection, and people's lives. Although it can handle a wide variety of objects and the goals required by people vary, the role of ultrafiltration can be attributed to the three functions of purification, separation and concentration.
(1) Application in industrial wastewater treatment
Industrial wastewater treatment is mainly used for: treatment and application of sugar-containing wastewater; treatment of crude oil-containing wastewater; treatment of various wastewaters combined with bioreactors; textile industry, dyeing and dyeing wastewater treatment and reuse; papermaking wastewater treatment; radioactive wastewater treatment, etc. For example, in the recovery of dyestuffs from printing and dyeing wastewater, when the dyeing factory shuts down for tie-dyeing, the vat steamer will discharge more vat dyes during the production process, which is both polluting and wasteful. Using ultrafiltration technology, using polysulfone and polysulfone amide ultrafiltration membrane, printing and dyeing wastewater can be treated without acid neutralization and cooling.
(2) Application in the pharmaceutical industry
Major applications in the pharmaceutical industry include: purification of antibiotics and interferons; injection and injection of water to remove pyrogens; plasma and biopolymer processing; separation, concentration and purification of proteins and enzymes; and purification and purification of Chinese herbal medicines. For example: the application of heat removal in the pharmaceutical industry.
(3) Application in water treatment
Water treatment applications mainly include: pure water for the electronics industry; pretreatment of high-purity water and reverse osmosis components; production of sterile water for beverages and cosmetics; production of sterile, pyrogen-free water for the pharmaceutical industry; production of reclaimed water such as mineral water, The water source must be groundwater, which will dissolve some inorganic salts when it flows into the ground. The combined process of ultrafiltration and microfiltration can produce mineral water that meets drinking water standards.
(4) Application in the food fermentation industry
The main applications in the food fermentation industry include: clarification and sterilization of wine; cooked soy sauce; sterilization, clarification and decolorization of vinegar; purification and refining of fermentation broth; clarification of fruit juice; recovery of sugar juice and sugar liquid; whey protein recovery; milk concentration, etc.
Indonesia 2200 tons/day water plant project
