Precision filters, also known as security filters. The housing is made of high-quality stainless steel. The filter cartridge adopts the formed filter material (polypropylene fiber melt-blown or wire-wound hive). Under the effect of pressure, the raw liquid passes through the filter material, the filter residue is left on the filter material, and the filtrate passes through the filter material. Outflow, can effectively remove impurities, sediments and suspended solids, bacteria in the water, so as to achieve the purpose of filtration.
Function 1, installed behind the pre-treatment system and the front of the reverse osmosis membrane, it blocks the filtered material run out from the pre-treatment system, to protect the reverse osmosis membrane; extend its life; Function 2, remove large particles suspended particles, colloids, impurities to achieve double filtration effect Precision filtration is the use of a shaped filter material, under the pressure of the role of the original solution through the filter, filter residue left on the filter wall, the filtrate through the filter out, so as to achieve the purpose of filtration. Formed filter media include: filter cloth, filter screen, filter, sintered filter tube, string wound filter, melt blown filter, microporous filter and multi-function filter.
Due to the different filter materials, the filter aperture is not the same. Precision filtration is a filtration between sand filtration (raw filtration) and ultra filtration. The filtration pore size is generally in the range of 0.01-120 μm. The same type of filter material is divided into different specifications according to the external dimensions. There are two kinds of wire wound filter (also known as honeycomb filter): one is polypropylene fiber-polypropylene filter, the maximum use temperature is 60 °C; the other is cotton fiber-stainless steel skeleton filter, the maximum use temperature is 120 °C. The melt blown filter element is a filter material formed from polypropylene as a raw material and melt blown. The maximum working temperature is 60°C. Life of 3-6 months. Due to the pollution of the retentate, the filter's operating resistance will increase. When the pressure difference between the inlet and outlet of the equipment is higher than the initial pressure difference by 0.15Mpa, the filter element shall be replaced in time.

Feature
