Particles are removed by way of absorption or physical encapsulation. If there is excessive pressure loss on the filter, it must be rinsed. A distinction can be made between continuous and discontinuous filters. In

Sand filtration Logisticon Water Treatment
Sand filtration is frequently used in the treatment of groundwater to remove dissolved iron. Iron and manganese in the groundwater are oxidised by aeration and the flocs formed are subsequently trapped in the sand filter. After a certain period of time, the filter is saturated with particles and must be cleaned to prevent it from blocking up completely. Sand filters are cleaned by backwashing

However, in most cases, filters used in municipal water treatment contain sand or another appropriate granular material (e.g. anthracite, crushed glass or other ceramic material, or another relatively inert mineral) as the filter medium. Filtration using such filters is often referred to
Filtration MRWA
Several types of filters are used for water treatment. Early slow sand filters typically have filter rates of 0.05 gpm/ft2 of surface area and require large filter areas. The top several inches of the sand has to be removed regularly--usually by hand--due to the mass of growing material ‘schmutzdecke’ that collects in the filter. Sand removed is usually washed and returned to the filter
