Water Filter Media for Water Filter Purification from Industrial Water Equipment Ltd

GARNET
TYPICAL USES, FINE PARTICULATE REMOVAL
APPLICATIONS, PART OF MIXED BED MEDIA FILTRATION SYSTEMS.

Garnet Filter Sand is used in the highest specification three layer multimedia filters in which the decreasing grain size in the direction of flow produces the ideal conditions for high filtration rates and long filter runs.

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 granular 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.

Advantages

High specific gravity aids a unique filer design.
In combination with other filtration media's higher flow rates better loading capacities and increased filtration can be achieved. A hard media will last longer than conventional products. Can act as a support bed for other filtration media saving room within the filtration equipment.
