Ultrafiltration equipment for Hainan minitype food machining plant
Technology performance parameters:
Ultrafiltration membrane components adopt PVC alloy ultrafiltration membrane, there are the following advantages:
Membrane material is the pollution resistance, hydrophilic modified PVC.
The flux is permanent and stable, the pollution resistance ability is strong.
It can bear the environment of 200ppm residual chlorine in the short time, the suitable PH range is 2-13.
Bacteria removal is thorough, the output turbidity is less than 0.1NTU.
The cross-flow design can eliminate sludge blocking, then improve the service life.
SDI15 of output is less than 1(the test value is that raw water turbidity is less than 20NTU)
Ultrafiltration components is a kind of hollow fiber inner-pressure ultrafiltration components, the inner diameter of ultrafiltration membrane hollow silk is 1.0mm,the average molecular weight intercepted of ultrafiltration membrane is 100,000 dalton. The material of ultrafiltration membrane is PVC, which has many advantages, such as good hydrophily, organic pollution resistance, acid-base resistance, no dirty blocking and so on. The ends of ultrafiltration membrane components adopt epoxy resin casting to seal. The ultrafiltration membrane can remove the suspended particles, colloids, microorganisms and so on in the water. Under the action of water pressure, hydrone and small molecular matter will permeate the ultrafiltration membrane, the suspended particles, colloids, microorganisms etc. in the water will be intercepted in the surface of ultrafiltration membrane, these intercept matters will gather together in the inner surface of membrane, therefore, we need to have the regular backwash and cleaning of adding agents to the ultrafiltration membrane components.
Application scopes:
Production of potable water(preparation of mineral water and beverage water);
Pretreatment and posttreatment of reverse osmosis, the kinds of raw water are sea water, surface water, well water and waste water and so on.
Heat source removal of pharmaceutical water.
Water supply of cities, towns and villages potable water.
Municipal water, surface and well water treatment for drinking.
The deep waste water treatment is just for the reuse.
Bacteria and turbidity removal of white wine, fruit wine, grape, yellow wine.
Concentration treatment of food, fermentation, diary industry.
Various dialysis, hemofiltration and so on in medical treatment industry.
Ultrafiltration precess
Under the action of pressure, the solvent and small solvend in the feed liquor will permeate the ultrafiltration membrane from high pressure to low pressure, then we can get the permeating liquid, which is also called ultrafiltration liquor; but the dimension of solvend is more than membrane aperture will be intercepted and become the concentrated liquor.
Ultrafiltration features
Ultrafiltration is the membrane separation process driven by pressure, the separation range of ultrafiltration membrane is the macromolecular matters and colloids with relative molecular weight 5-1 million, the relative particle diameter is 0.005-0.1μm; separation mechanism is generally thought that mechanical screening ultrafiltration membrane components have plate-type, rolling type, tube type, capillary and hollow fiber and so on, the filtration method is the cross-flow filtration.
