Cartridge filters are preferable for systems with contaminations less than 100 ppm, that means with contamination levels less than 0.01% by weight and can be realized as surface or as depth-type filters. For concentrations that are bigger than 100ppm then a bag filter, filter press, or some other method should be used instead of cartridge filters.

Depth-type cartridge filters capture contaminations through the total thickness of the medium, while in surface filters (usually made of thinner materials like papers, woven wire cloths) particles are captured at the surface of the filter. 

Cartridge filters are also designed disposable, which means that they have to be replaced when the filter is clogged.

Cartridge filter housing

Cartridge filter system offers wide range of flow capacities & contaminant holding capacities. Cartridge filter housing diameters can accommodate from 1 to 200 cartridges around. Cartridge filters are normally used as polishing filter in almost all process industries. Cartridge filter is constructed of filter housing, filter cartridges, tube sheet, positive sealing arrangement for cartridge depending upon type of cartridge & choice of end connections. Positive sealing arrangement for cartridge filter assures no particle migration or fiber migration, even after high differential pressures.

Operation

Contaminated fluid enters the housing and is distributed evenly around the filter cartridges. Filtration takes place from outside to inside. Solids are collected on the outside of filter cartridges & clear filtrate collected at outlet.
