Features:
Garnet is ahigh hardness, high density granular filter media. It is normally used as the lower (final) filtration layer of a multi-bed down flow filtration system.
Garnet water filtration media is achemically static, non-metal mineralordinarily found in nature.
Garnet water treatment media is a highly dense granular mineral, its hardness, chemical, and durability properties makes Garnet a superior filter media and abrasive media.
Garnet filter media is used as asupport bedin backwashing filters with filter medias such as Pyrolox, Calcite, Sand, Greensand or Birm.
High hardnessreduces attrition and provides for years of reliable service.
Garnet water treatment media is an excellent support bed for other high density medias.
Garnet water filter media is typically used in multi-media filters as thesub-fill or bottom layers of the filter. Although its density requires high backwash rates, combining fine mesh garnet with other media such as sand and anthracite significantly increases the filtration capacity of a system.
Garnet with its high specific gravityof 4.0 forms the lower fine grain layer, its 0.3 mm effective size can filter down to the 10-20 micron range. Filter sand (e.s.= 0.5 mm) and anthracite (e.s.=0.9 mm) or filter -Ag can form the larger less dense layers.
For the majority of municipal and industrial water supply applications, a filter bed composed of 55% low density material, 30% medium density material, and 15% high density material is recommended. Garnet media, sized per requirements, is the ideal high density material.
