• the principle of ultra filtration

    Membrane pore size range of 0.001-o.1microns about1000-500000dalton MWCO, under pressure ,small than the membrane material such as water , ions and small molecules, become super-filtrate, and macromolecular substance such as colloidal particles bacteria   entrapped as concentrate liquor by membrane Thus achieve the purpose of filtration and separation.
2) Ultra filtration membrane pollution and control 
    Ultra filtration once operated ,also following the polluted problem to the velum .the pollution is absolute, so we can do is slow down and control the pollution of membrane, by the suspended solid or soluble substance deposited on the membrane surface or in the micropore result in membrane flux reduction process is called membrane fouling, control membrane fouling in following ways: modification of membrane materials ,reasonable operation ways, membrane material modification is to make the membrane hydrophilic and pollution resistance. Membrane module is designed to filter in the design to minimize dead spots and connect points to select the operation mode of cross flow backwash is red chemical cleaning and other measures to stabilize and restore the membrane flux. technology parameters
