Embedded flow media diffuser for liquid media filter

摘要

A floating media filter including a filter housing having an influent inlet and an effluent outlet. A floating media is positioned in the housing and forms a static media bed when the filter is in a filtration stage. A diffuser trough is positioned in the filter housing such that the lower surface of the media bed, when the filter is in the filtration stage, is below the upper edge of the diffuser trough. A backwashing mechanism causes dispersion of the media bed during the backwashing stage.
