I. Operation principle.

Precision filter mostly adopts filter cloth, filter mesh, filter sheet, sintered filter tube, wire-wound filter element, meltblown filter element, etc. as filter elements, under pressure, so that the raw water passes through the filter material, the filter slag stays on the wall of the tube, and the filtered water flows out through the filter material, so as to achieve the purpose of filtration, and the precision filter can remove suspended matter, certain colloidal substances and fine particles in water.

Second, the scope of application.

Precision filter is widely used in the pre-treatment and post-treatment system of water in the fields of electronics, petroleum, chemical industry, medicine, food and so on. Generally installed in electrodialysis and reverse osmosis before and after the ion exchange bed.

Three, performance characteristics.

1, high filtration precision, small volume, large filtration area.

2, low filtration resistance, high energy, high dirt interception capacity and long service life.

3, high cleanliness of the filter element material, no pollution to the filter medium.

4、Resistant to acid, alkali and other chemicals.

5, high strength, high temperature resistance, the cartridge is not easily deformed

6, low price, low operating cost, easy to clean, cartridge can be replaced, small footprint, etc.

IV. Equipment composition.

Precision filter shell material: organic glass, stainless steel, glass steel, carbon steel anti-corrosion, etc., generally made into a cylindrical container, filled with filter material, plus the combination of operation pipe valve, etc. The precision of filter element is 0.2, 0.45, 1, 3, 5, 10, 20, 30, 50, 75, 100μm, etc. The water quality and water volume are different when different precision filter elements are selected. The specific specification, material, filter material and precision depend on the water requirement and according to the actual situation. The specifications are Øl50----1500mm, and the water output is from lt/h²-50t/h².
