Various sand, garnet, and zeolite media particle sizes and base materials are selected for differing liquid filtration goals and capacities, particularly to remove suspended solids from water and wastewater. Traditional sand and gravel with anthracite and garnet materials have specific capabilities when used in various combinations. Zeolite based material is a newer product compared to more conventional media mixes and offers the advantage of lower density, thereby giving higher bed expansions at similar flows with traditional liquid phase media.
Operating ranges of sand and garnet media include process flows at typically 4-6 gpm/ft2 with back-washing requirements changing with the particular media packs. Gravel, sand, anthracite, and garnet sizing is available upon request.
Activity provides an indicator of the capability of the particular filtration media combination to produce a particular effluent quality and the capacity of the media pack.
All garnet, sand, and zeolite media packs have the capability to produce suspended solids reduction in applications having particles above 10 microns. Polishing filtration may be required for downstream processing. Back-washing requirements for these products range from 12-15 gpm/ft2 with anthracite to 15-20 gpm/ft2 with sand and gravel.

Types of activated carbon filter media, with various particle sizes, base materials and activity may be selected for pressure drop considerations and application parameters including type of contaminant and concentration.
Traditionally, coal-based carbon filter media have been preferred as they provide excellent performance for contaminants and a broad range of concentrations. Coconut carbon filter media have generally performed well with low boiling point, low molecular weight compounds at lower concentrations. Wood based carbon media offer superior decolorization properties.
The smaller mesh sizes are more suitable for units with lower flow rates or where it is desired to compress the active adsorption zone while the larger mesh sizes offer better pressure drop characteristics or better yields in a reactivation service cycle.
Activity gives an indication of the capability of the particular adsorbate to provide surface loading. Higher values generally indicate a greater capability to provide surface loading.
All virgin liquid phase activated carbon filter media are capable of producing non-detectable effluent quality for adsorbates which are cost-effectively adsorbed. Reactivated carbon filter media are available for application where lower capacity and less stringent effluent quality will permit better cost-efficiency.
