If the filters are full of trapped solids, They're back-washed. With this process, thoroughly clean water and air are pumped back again up the filter to dislodge the trapped impurities, and also the water carrying the Dust (known as backwash
Filtration could be the process wherever solids are separated from the liquid. In water treatment, the solids that are not divided while in the sedimentation tank are removed by passing the water as a result of sand and gravel beds.
