www.cpheeo.gov.inSlow Sand filtration was the first type of porous media filtration used in water treatment. This process is known for its simplicity and efficiency. During the initial operational period of slow sand filters, the separation of organic matter and other solids generates a layer of biological matter on the surface of the filter media.

cms.qut.edu.auFiltration is also another important element of the treatment process. This process involves the water passing through a bed of fine particles, usually sand. This process is called sand filtration. Other materials are also used in the filtration process. Generally they are layered. Originally filtration was a slow process, however because the sand

Suspended matter - when it is larger than 5-10 µm can be removed quite easily by filtration or sedimentation and filtration. The removal of colloids is possible by slow filtration in cases the water is not strongly polluted. 1. Adsorption of potential determining ions.

Filtration - MRWA
www.mrwa.comfiltration. Most rapid sand filters contain 24-30 inches of sand, but some newer filters are deeper. The sand used is generally 0.4 to 0.6 mm in diameter. This is larger than the sand used in slow rate filtration. The coarser sand in the rapid filters has larger voids that do not fill as easily.
