Ultrafiltration

Ultrafiltration(A) Principle:Ultrafiltration is a micro membrane sever technology,depending on the tangential fluid flow and pressure-driven filtration process with aparted particles,making different pressure as power, raw material flowing into the membrane surface. Solvent and small solutes in the raw materials penetrate from high-pressure to the low-pressure side,so the dissolved substances and the substances smaller than aperture can notgo through membrane. thus,this process achieves the target of purification,separation and enrichment.(B) Main separated substances:Colloid(non-activated silicon,iron and aluminium),bacteria,virus and protozoa other microorganisms,in 2000-50 Dalton molecular weight of macromolecules.(Proteins,amino acids,enzymes and so on).(C) The characteristics of ultrafiltration:1. UF technology is a high technology achieving solution purification,separation and concentration. It is an high efficient,environmental and energy conservation separating process.2 .With lower pressure as driving power to separate particles according to the size of molecular. Such as the production of pure water and mineral water,reuse of industrial water.3. UF separate process operates in room temperature,low power,no transformation. It has a particular application in food-processing,pharmaceutical industry,bio-technology and other fields.4. Ultrafiltration process with wide scale and strong treating ability,with compact structure,easily aparted and combined with another components,automatic control. For example,UF+RO, a best combination of membrane style desalination treatment.5. Ultrafiltration membrane silk with strong resistance oxidation,wideraw liquid treatment Ultrafiltration membrane silk modified by hydropile,inner and outer wall smooth with strong pollution resistance,membrane silk water yield attenuation rate islowered withinuni time.
