Cartridge filtration units generally operate most effectively and economically on applications having contamination levels of less than 100 ppm. For heavier contamination applications, cartridges are normally used as final polishing filters.

It can be generally stated that if the size of filter surface is increased, higher flows are possible, the filter last longer, and the dirt holding capacity increases. Cartridge filters are normally designed disposable: this means that they have to be replaced when the filter is clogged.

Cartridge filter can be surface or depth-type filter: depth-type filters capture particles and contaminant through the total thickness of the medium, while in surface filters (that are usually made of thin materials like papers, woven wire, and cloths) particles are blocked on the surface of the filter.

Surface filters are best if you are filtering sediment of similar-sized particles. If all particles are i.e. five micron, a pleated 5-micron filter works best because it has more surface area than other filters. Compared with pleated surface filters, depth filters have a limited surface area, but they have the advantage of depth.

Applications of cartridge filters:

• Pre RO water
• Chemicals
• Beverages
• Solvents
• Compressed air
• Cosmetics
• Alcohol

THERE ARE VARIOUS TYPES OF CARTRIDGE FILTERS:

WOUND CARTRIDGE FILTERS:

Material: natural or synthetic yards, which are wounded around a central tube or former.
Filtration of: sand, scale, lime, rust, fine particles.
Applications: drinking water, boilers, washing machines, pre-filtration in water treatment, sea water desalination, process water, chemical processes.
