Ultrafiltration

Ultra Filtration Unit Specifications
Ultrafiltration membrane adopts nanoscale physical aperture to make substances in material liquid separate, refine, purify and concentrate the major function is to remove suspended matter, colloid, microorganism, bacterium, virus and organic macromolecules in liquid. Also it can decolorate, remove oil and drop turbidity, SDI, COD and BOD of the liquid.
Filtration principle of ultrafiltration membrane: Hollow fiber ultrafiltration membrane component adopts advanced Membrane separation technology. The ultrafiltration membrane is of double layer structure and you can choose internal pressure type and external pressure type. Usually we recommend internal pressure type for you. It can separate under normal temperature and normal pressure with the advantages of low energy consumption, high precision filtration, high water production rate, high pollution-resist capacity, and so on. This ultrafiltration membrane can effectively remove bacterium, colloid, suspended matter, rust, organic macromolecules and other harmful substances in water in order to make water quality clean and sanitation.
When running the ultrafiltration membrane for the first time, you should wash off protection solution inside membrane and drive away air inside membrane component with feeding water of low pressure and low flow rate. Water feeding pressure should controlled to be low enough and feed the water from memebrane bottom. All water production and concentration water should be discharged during the whole washing process. Washing time is 5-10 minutes until the water production has no foam or no objectional odor. (In future each open and stop will invole with the sudden changing of system pressure and flow and also impact on membrane component, and so on. Therefore, you should reduce times of opening and stoiping for openning and stopping as possible as you can. Normal opening and stopping also should be controlled as smoothly and steadily as possible, especiallyto make sure that feeding water pressure and flow rise slowly. )
