Principle of Cartridge Filter
Cartridge filters operate on the principle of surface and depth filtration, using replaceable filter cartridges to trap particles from fluids.
They are widely used for their ease of replacement and versatility.
Construction
Filter Cartridge: Cylindrical filter element made of materials like polypropylene, cellulose, or activated carbon.
Filter Housing: Holds the cartridge in place, often made of plastic, metal, or stainless steel.
Inlet/Outlet Ports: For fluid entry and exit.
Seals and Gaskets: Ensure no bypass of unfiltered fluid.
Working
The fluid enters the housing through the inlet port.
It flows through the filter cartridge, where particles are trapped on the surface or within the material.
The filtered fluid exits through the outlet port.
When the cartridge becomes clogged, it is replaced with a new one.
Uses
Water purification
