Cartridge Filter for Seawater Brackish Water Desalination Water Treatment

Cartridge Filter for Seawater Brackish Water Desalination Water Treatment

Cartridge filter, also known as security filters, generally set before the pressure vessel to remove the tiny particles whose turbidity above 1 degree, to meet the requirements of  the follow-up process of water; sometimes, it is also set at the end of the entire water system to prevent small particles (such as broken resin) into the finished water.

Working Principle
Cartridge filter, also known as security filter. The shell is made of high quality stainless steel, filter using molded filter, The liquid went through filter under pressure, residue left on the filter, and the filtrate outflow through the filter can effectively remove impurities in the water, sediment and suspended solids, bacteria.
Molded filters are: cloth, screen, filter, sintered filter tube, wound filter, melt-blown filter, micro-porous filter and multi-function filter. 
Due to different filter, the filter pore size is not the same. Precision filter is between the sand filter (coarse) and a filter between ultra-filtration, filter pore size generally between 0.01-120um.For the same form of filter,it is divided into different models by their dimensions.

Commonly used wound filter and meltblown filter 
Wound filter (also known as honeycomb filter), there are two types: one is polypropylene fiber - polypropylene skeleton filtration, the maximum temperature 60 ºC; the other is cotton fiber - stainless steel frame filter, the maximum temperature 120 ºC. 
Raw material of meltblown filter is polypropylene, the maximum operating temperature is 60 ºC. 
Sophisticated filters can remove suspended solids, colloidal substances and some fine particulate matter and so on.

Composition
Cartridge filter is mainly composed by the filter housings, filter cartridges and other components, and the filter housings materials is mostly made of R304 stainless steel, if it's used in the acid and other special occasions,it will be made by R316 stainless steel. It an be divided into the flange and clamp, and flanged housing is mainly used in the occasion of larger flow filtration. The filter is mainly made by PP cotton, it can also be made by wound filter or activated carbon filter on some occasions. The number of filter may vary from 1 to dozens, primarily be determined from the water flow rate.
