Granular Media Filtration - Trussell Technologies, Inc.

A granular media filter can only be operated for a certain amount of time before the removed solids result in enough head loss that the filter media requires cleaning. The cleaning process is referred to as backwashing and involves flushing water (and possibly air) backwards through the filter at a high rate.

CIVL 1101 - Introduction to Water Filtration

Gravity filtration through beds of granular media is the most common method removing colloidal impurities in water processing and tertiary treatment of wastewater.

Granular Media Filters. Granular media filtration is generally used after gravity separation. It removes additional suspended solids and oils before other treatment processes. It is also a polishing step that lowers the levels of suspended solids and associated contaminants in treated wastes.

Backwashing (water treatment) - Wikipedia

Backwashing of granular media filters involves several steps. First, the filter is taken off line and the water is drained to a level that is above the surface of the filter bed. Next, compressed air is pushed up through the filter material causing the filter bed to expand breaking up the compacted filter bed and forcing the accumulated ...
