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.

Granular Media Filtration - Drinking Water - Climate ...

Granular media filtration is used for treating aqueous waste streams. The filter media consists of a bed of granular particles (typically sand or sand with anthracite or coal). The anthracite has adsorptive characteristics and hence can be beneficial in removing some biological and …

Granular Media Filters - The McIlvaine Company

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.

Filtralite - Biological Water Filtration Media - Sapphire ...

Granular filtration is a water treatment process that uses granular material such as Filtralite® expanded clay, sand, anthracite, and other types of granular filtration media to remove impurities. Granular filters are most effective in removing suspended particles like sand, clay, iron and aluminum flocs along with biological matter such as bacteria, algae, protozoa and other pathogenic micro ...
