Precision filtration, also known as the security filter. It is the raw water into the reverse osmosis membrane before a process of the device. PP filter, filtration has large flow, the large amount of pollution, pressure loss small features, and can tackle the impurity particles different particle size, surface filtering and deep set filter in one body.

The security filter equipment in the line around the hive type filter or spray melt filter core, used for drinking water, the water for living, electronics, printing and dyeing, textile, environmental protection and other industry production water filtration, alcohol filtering, pharmaceutical filtering, acid and alkali filtering, reverse osmosis RO film former security guard filtering, flux big, consumables, lower cost, and polishing or inferior smooth appearance, inside surface pickling passivation treatment. Import and export, sewage pipe with automatic control valve, controller, but automatic recoil washing.

The security filter characteristics: cylindrical shell, 304 barrel and base way.this way: open type, flange type; , 316 L stainless steel, carbon steel and optional resin shell; Match with single or more a filter. The security filter often set in after pressure filter, used to remove the small particles in the liquid, in order to meet the requirements of the follow-up process to water. Sometimes also set in the full set of water treatment system does not end, to prevent tiny particles into the finished product water.

Commonly used filter has the following kinds of specifications: 0.1, 0.2, 0.5, 0.8, 1, 2, 3, 5, 10, 20, 30, 50, 75, 100, 120 μ m, the security filter often as electrodialysis, ion exchange and the reverse osmosis, ultrafiltration device such as the security filter of use.
