3000L/H raw water treatment ultrafiltration equipment

Ultrafiltration (UF) is a membrane separation technology that can purify and separate solutions. The ultrafiltration membrane system is a solution separation device that uses ultrafiltration membrane as the filtration medium and the pressure difference on both sides of the membrane as the driving force. Ultrafiltration membranes only allow solvents (such as water molecules), inorganic salts, and small organic molecules in the solution to pass through, while intercepting large molecular substances such as suspended solids, colloids, proteins, and microorganisms in the solution, thereby achieving the purpose of purification and separation. The range of pore size and molecular weight cut-off of ultrafiltration membranes is generally considered to be 0.001-0.1 micrometers, with a molecular weight cut off (MWCO) of 1000-1000000 Dalton. Ultrafiltration equipment is mainly used to intercept and remove large molecular substances such as suspended solids, colloids, particles, bacteria, and viruses in water. The work of ultrafiltration membrane is mainly based on screening mechanism, and water purification treatment is carried out by working pressure and membrane pore size.

Working principle of ultrafiltration equipment:

Ultrafiltration is a membrane separation process that uses sieving as the separation principle and pressure as the driving force. The filtration accuracy is in the range of 0.005-0.01 μ m, and it can effectively remove particles, colloids, bacteria, heat sources, and high molecular weight organic substances from water. It can be widely used for the separation, concentration, and purification of substances. The ultrafiltration process has no phase transformation and operates at room temperature, making it particularly suitable for the separation of thermosensitive substances. It has good temperature resistance, acid and alkali resistance, and oxidation resistance, and can be used continuously for a long time below 60 ℃ and pH 2-11.

3000L/H raw water treatment ultrafiltration equipment Application fields:

Mineral water: In the production of mineral water, ultrafiltration technology is applied. In engineering design, the pore size and membrane type of the membrane will be selected according to the water quality analysis report of the mineral water source, and ultrafiltration design will be designed accordingly.

Food: Ultrafiltration technology is gradually adopted in the production of dairy products, fruit juice, wine, seasonings and other food products, such as the separation of protein and low molecular weight lactose from water in milk or whey, clarification and sterilization of fruit juice, removal of colored proteins, polysaccharides and other colloidal impurities in wine, and removal of bacteria in soy sauce and vinegar. Compared with traditional methods, it has shown advantages such as economy, reliability and quality assurance.

Medicine: In the production of medicine and biochemistry, it is often necessary to separate and purify thermosensitive substances, and ultrafiltration technology has shown its outstanding advantages in this regard. The use of ultrafiltration to separate and concentrate bioactive substances (such as enzymes, viruses, nucleic acids, special proteins, etc.) is quite suitable for extracting drugs from plants and animals (such as alkaloids, hormones, etc.). The extract often contains large molecules or solid substances, which can be separated by ultrafiltration in many cases to improve product quality.

Pure water and ultrapure water: primary purification of industrial water, RO pretreatment for pure and ultrapure water preparation, and terminal treatment for pure and ultrapure water.

Environmental Protection: Advanced treatment of industrial wastewater, urban water reuse system, recycling of electrophoretic paint and oil products.

Fermentation: Separation and refinement of biochemical fermentation broth, concentration and refinement of enzymes, etc
