Description

A8037-01 Garnet #30-40 (0.38 Cu/Ft Bag)

Garnet is a high hardness, high density granular filter media. It is normally used as the lower (final) filtration layer of a multi-bed down flow filtration system. Called Multi-Media or Mixed Media filtration, the high density small grain size of Garnet solves a major filtration problem. In a single media granular filter such as a sand filter, the material will hydraulically classify during back­wash according to granual size, the smallest rinsing to the top. When water flows downward through the sand, the fine particles at the top of the bed do most of the straining of the sediment. The solids form a cake on the surface with filtration typically taking place in the top few inches. As the cake forms, the filtration becomes finer and head loss increases exponentially in time.
