Sand Filter - an overview ScienceDirect Topics

Rapid sand filters are divided into two main types: (1) gravity filters and (2) pressure filters. The principles of the two types of filters are identical. The pressure filter is operated at elevated pressures, thus prolonging the filter cycle and/or increasing the rate of flow of water through the filter.

Sand filtration EMIS

A sand filter can be placed in various phases of water management - as a pre-treatment, as side-stream filtration and as a polishing filter. A sand filter often provides an effluent with potential for re-use. However, chemicals sometimes need to be added to improve the yield of the sand filter. A disadvantage of sand filtration is the rinse water that is created when the sand filter is cleaned. This heavily polluted water
