1、 Working principle of security filter

Security filterEquipped with a precision filter element, the security filter element generally adopts an external pressure type. 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 precision of the security filter element is100um，50um，30um，20um，10um，5um，1um，0.45um，0.22um，0.1um.

2、 Security GuardfilterInstrument function

Security filters are generally used after quartz sand filters, activated carbon filters, and ion exchangers. On the one hand, they are

Further processing of fine impurities in the water, while preventing the breakage of quartz sand, activated carbon, and ion exchange in the previous process

Leave it through the water distributor for the next process.

3、 Types and characteristics of security filter cartridges

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.
