Overview of Copper Powder Sintered Filters

The copper powder sintered filter can protect the water treatment system and ensure that the effluent quality meets the standard. Its interior uses a wire-wound honeycomb filter element or a melt-blown filter element, which is used for production water filtration, alcohol filtration, pharmaceutical filtration, acid-base filtration, reverse osmosis in drinking water, domestic water, electronics, printing and dyeing, textile, environmental protection and other industries. The copper powder sintered filter before RO membrane has large flux, low cost of consumables, surface polishing or matt, and inner surface pickling passivation treatment. The inlet and outlet and sewage pipelines are equipped with automatic control valves and controllers, which can automatically recoil.

The copper powder sintered filter adopts a shaped filter material, the original solution passes through the filter material, the filter residue remains on the wall of the filter material, and the filtrate flows out through the filter material, so as to achieve the purpose of filtration.

The formed filter materials include: filter cloth, filter screen, filter disc, sintered filter tube, wire wound filter element, meltblown filter element, microporous filter element and multi-functional filter element. Due to the different filter materials, the filter pore size is also different.

Precision filtration is a kind of filtration between sand filtration (coarse filtration) and ultrafiltration, and the filtration pore size is generally in the range of 0.1-120 μm. The same form of filter material is divided into different specifications according to the external size. There are two types of wire-wound filter elements (also known as honeycomb filter elements): one is polypropylene fiber-polypropylene skeleton filter element with a maximum operating temperature of 60°C; the other is absorbent cotton fiber-stainless steel skeleton filter element with a maximum operating temperature of 120°C.

Characteristics of copper powder sintered filter

3. Performance characteristics

(1) High filtration precision and uniform filter element aperture;

(2) Small filtration resistance, large flux, strong interception capability, and long service life;

(3) The filter element material has high cleanliness and no pollution to the filter medium;

(4) Resistant to chemical solvents such as acid and alkali;

(5) High strength, high temperature resistance, and the filter element is not easy to deform;

(6) Low price, low operating cost, easy to clean, and replaceable filter element.

The role of copper powder sintered filter

The copper powder sintered filter is often installed after the pressure filter to remove fine particles in the liquid to meet the requirements of the subsequent process for water intake. Sometimes it is also set at the end of the complete water treatment system to prevent fine particles from entering the finished water. , 75, 100, 120μm, copper powder sintered filters are often used as copper powder sintered filters for electrodialysis, ion exchange, reverse osmosis, ultrafiltration and other devices.
