1Precision filterintroduce
Precision filters, also known as security filters, microporous membrane filters, and filter cartridges with high flow ratesΦ 152 filter element, using precision filter element with internal pressure, and Φ 62The filter element generally adopts external pressure, and water passes through the small micropores of the filter element and enters the center pipe of the filter element to discharge water. The micropores intercept small impurities in the water quality, and their ability to intercept impurities is mainly determined by the aperture of the filter element. The accuracy of the filter element in the general market is100um，50um，30um，20um,10um,5um，1um，0.45um，0.22um，0.1um.
2、 PrecisionfilterInstrument function

Precision filters are generally used behind quartz sand filters, activated carbon filters, ion exchangers, or in front of reverse osmosis membranes, ultrafiltration membranes, and nanofiltration membranes. On the one hand, they further treat small impurities in water, and on the other hand, they prevent the breakage of quartz sand and activated carbon in the previous process. Ion exchange impurities are retained in the next process through the water distributor.

3、 Precision filterfilter elementTypes and characteristics

1Meltblown filter cartridge, features: low price, generally with a pore size of3umAbove, there is a large market demand.

2Wire wound filter element Features: Low price, aperture generally in the range of3umThe above can be cleaned and reused.

3Folding filter cartridge Features: High precision, high cost, generally used in the subsequent treatment of pure water.

5、 The function of precision filters
Precision filters are often set at pressurefilterAfterwards, it is used to remove fine particles from the liquid to meet the requirements for water inflow in subsequent processes. Sometimes it is also installed at the end of the entire water treatment system to prevent small particles from entering the finished water. The commonly used filter cartridges have the following specifications: 0.1 0.2 0.5 0.8, 1 2. 3 5. 10, 20 Precision filters with sizes of 30, 50, 75, 100, and 120 μ m are commonly used as security filters for devices such as electrodialysis, ion exchange, reverse osmosis, and ultrafiltration.
