Hollow fiber ultrafiltration is membrane technology whitch widely used for the separation of macromolecules
concentration and purification.
In the ultrafiltration process,the aqueous solution at a pressure driven flow through the membrane surface,the solvent(water) and small solutes permeable smallerr than membrane pores pass and become decontamination liquid(liquid diltration),which larger than the membrane pores will be trapped and discharged liquid.Ultrafiltration process is dynamic filtration,separation is accomplished in the flow state.Solute only limited deposition on the membrane surface,ultrafiltration rate reduction to some extent and tends to balance,and can be rstored by washing.
Uitrafiltration is a pressure film separation technology,that is,under certain pressure,so that the solvent and small solutes
through a special film certain aperture,leaving the impermeable aolute molecules,leaving the side of the membrane,so that the macromolecules has neen purified.Macromolecules and small molecules separation is the final purpose.
Working process of water UF system:
1. Raw water pump-- provide the pressure to quartz sand filter/active carbon filter.
2. Multi-medium filter-- get rid of turbidity, suspended matter, organic matter, colloid, ect
3. Active Carbon filter--Remove the color, free chloride, organic matter, harmful matter, ect.
4. Softener--exchange "ions" of calcium and magnesium with the most common and easiest method.
5. Micron filter--prevent large particles, bacteria, viruses into UF membrane, accuracy is 5um,
6. High pressure pump-- Provide the high pressure to UF membrane
7.UF system-- main part of the plant. The UF membrane's desalting rate can reach 99%
