Cartridge Filter

Water is passed through cartridge filters for cleaning in tilapia farming. The Cartridge filter is a selective barrier consisting of a membrane type filter and screen type filter elements. Among the filters used in hatcheries, the finest selectivity is 0,2 µ, the thickest selectivity is 100 µ. Generally used filters are between 0,5 µ to 2 µ selectivity.

The choice of cartridge filter depends on tilapia farming application. They are preferred for less than 100 ppm polluted systems (ie less than 0.01% by weight). The cartridge filter may be surface or depth type filters. Depth-type filters capture particles and become contaminated throughout the total thickness of the media, while surface filters (usually made of woven wire, fabrics and paper) block the particles on the filter surface.
