water filters membrane hollow fiber MWCO:from 5k to 500k Dalton Material:PVC,PAN,PVDF,PP,PS,PES Dia:4", 6", 8", 10"
water filters with UF Membrane for water filtration & separation.
Hollow fiber ultrafiltration membrane is one of the most natured and advanced ultrafiltration technologies. The outer diameter of the membrane is 0.4-0.6mm or 1.5-1.6mm, inside diameter is 0.3-0.5mm or 0.9-1.0mm. The micropores distribute around the wall of the membrane. The entrapping molecular weight scale is about several thousand to ten thousand. The water flow from the outside of the membrane to the inside, it is outer pressure type. In adverse, it is inside pressure type. The ultrafiltration is a dynamic process, and the entrapping matter can be drained out following the concentration water.
Ultrafiltration technology is a new kind of high technology, which can be widely used in separation, concentration and purification of substance in foods, drinks, medicine and other industries.
Applications for :
• Pretreatment for Reverse osmosis and DI system
• Terminal filtration for super-purified water.
• Drinking water and mineral water treatment.
• Underground water treatment
• Food & beverages industry of bean, milk, sugar, alcohol, tea juice, vinegar concentration, separation, and purified.
• Living wastewater and industry wastewater treatment and recycling waste water to process water
• Electrophoresis lacquer recover
• Pharmaceutical industries
• Power Supply Plant
• Oil & Gas industry
• Surface water treatment i.e rural & municipal
Advantages of Ultrafiltration:
• Filtration down to 0.01 micron
• Removes bacteria and viruses of water up to 99%
• Fully automated control system for backwashing process
• SIMPLEST installation and operation
• Compared to conventional pretreatment technology, Ultrafiltration is simple which only requires a single process pretreatment for influent water.
• Absolute cost savings & reduction in maintenance cost
• Prolong the lifespan of RO membrane from 2 years up to 5 years
• Concentration and separate big molecule matter, colloid and organic in water, entrap bacteria, algae etc.
• Specially design to meet the flowrate required and space savings
• No maintenance cost
