Security Water Filter for Water Treatment Plant

Stainless steel security filter Brief introduction
The cartridge filter is made of 304 or 316L stainless Steel. With the advantages of light-weight, easy to use, large filter area, high filtering speed and non-clogging, it is widely used in pre-treatment and filtration.
This filter could be equipped with different filter element, such as PP melt-blown cartridge, pleated cartridge filter, string-wound filter and activated carbon filter. The models are varied from 10" to 40".
Rapid filter includes clamp filter and flange filter. The biggest pressure capacity of clamp filter is 0.6Mpa,and the flange filter is 1.0Mpa. The maximum of pressure capacity could be 1.6Mpa.

Stainless steel security filter product principle
The shell of stainless steel cartridge filter is made of high quality stainless steel; the filter element is made of formed polypropylene melt-blown fiber.  The stock solution will get through the filter material under pressure, any impurity, precipitate, suspended matter and bacteria would be removed.
Stainless steel security filter Product Overview
The cartridge filter is usually installed before pressure vessel in order to get rid of the small particles when the turbid degree is more than 1 and meet the demand of inflow. Sometimes, it could be installed at the end of whole water treatment system to prevent the small particles from going to finished water. The shell of cartridge filter is made of high quality stainless steel and the filter element (such as PP cotton) is put inside. It is installed between the multi-medium prefiltration and the inverse permeability filter, ultrafiltration membrance filter. It could remove the small particles (such as small quartz sand and active carbon granule) in order to ensure the water filtration precision and prevent the membrane filter elements from damaging which caused by large particulate matter. Filter precision level varied from 0.5μm-100μm, it is chosen according to different purpose so as to ensure water precision and the safe of membrane element.

Stainless steel security filter function and characteristic
a) It can bear higher filtration pressure and get rid of impurities such as suspended matter, rust effectively.
b) The filter element could be made of many materials so as to meet the need of different fluid filtration.
c) Small size, large filtering area, small resistance force, long service life.
d) Acid and alkali resistance.
e) High filtration accuracy, uniform pore, high strength, resistance of high-temperature and good dimension stability.
6) Low filter resistance, high filtration flux, effective sewage interception, long service life.
7) The filter media can't be polluted because of the high cleanliness of filter element material.
8) Cheap, low running cost, easy washing and the filter element could be replaced.
