Our Filter media products are the highest quality media and adhere to the most stringent specifications. Granular Activated Carbon, Birm Media, Anthracite, Green Sand, Manganese Dioxide, Calcite, Pebbles & Sand.
Silex is made from pure quartz ground to 2-3 mm particle size. This high quality silex is used in water filtration and water treatment applications. Our silex is white and clear of any impurities and matches the highest standards. A silica sand used as an under-bed for ion exchange and carbon filters.
Anthracite promotes higher service flow rates and longer filter runs with less head loss than single media filter beds. Backwash rates are reduced as well. Low uniformity coefficient anthracite filter media extends the life of your filter before the media must be changed out. Low uniformity coefficient anthracite typically produces consistent improvements in turbidity removal, due in part to more efficient solids loading. Plus, low uniformity coefficient media produces smaller changes in effluent turbidity during periods of peak influent turbidity. Our anthracite filter media is produced from the highest quality anthracite available to ensure the physical characteristics of hardness, durability and performance.
·Higher service flows and longer filter runs than equivalent filters
·Unique density allows Anthracite to be combined with other filtration media in multi-media filters
·Close attention to gradation, hardness and purity assures consistent and reliable performance
·Lower uniformity coefficient has less oversized and undersized particles resulting in a highly uniformed bed
·Bulk Density: 50 lbs./cu. ft.
·Specific Gravity: 1.6 + .05
·Effective Size: 0.60 – 2.30 mm
·Uniformity Coefficienty: 1.3 – 1.7
·Hardness: 3.0 – 3.8 (Mohs scale)
·Bed depth: 24 – 36 in., 10 - 18 in. for multibed filters
·Freeboard: 50% of bed dept (min.)
·Service flow rate: 5 gpm/sq. ft. or higher depending upon local conditions
·Backwash flow rate: 12 - 25 gpm/sq. ft. depending upon mesh size
·Backwash expansion rate: 20 – 40% of bed depth
Garnet Sand Physical Characteristics:
Cleanliness: Low dust
Durability: Because of its hardness, high specific gravity and the pounds per cubic foot, garnet sand, when installed correctly, stays in its own layer holding down the layers underneath during backwash.
The layers above the garnet sand are lighter in weight (per cubic foot) and therefore they lift during backwash and dislodge the "floc" cleaning of the filter media. The Garnet sand is not used to replace silica sand but rather one or two support layers of garnet sand are used beneath the silica sand. Garnet sand is so durable and heavy that the layers above will be replenished or replaced well before the garnet and filter rock layers are replaced. Therefore, time and money are saved by using garnet sand in a filtering system.
Activated Alumina is a filter media made by treating ore so that it becomes highly porous and highly adsorptive. Activated Alumina will remove a variety of contaminants includng excessive fluoride, arsenic and selenium. The medium requires periodic cleaning with an appropriate regeneration with alum or acid.
It is used for fluoride removal in fluoride removal plant.

Our fine washed fine gravel is between 2-5mm and is composed of quartz aggregate. Our water treatment gravel is free of organic and calceous impurities. Typically used in multi-media filters as the under-bed, or bottom layer 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.
Uses for our gravel:
· For packing in bore wells / tube wells
· As a filter media in water filtration plants
· In effluent and waste water treatment plans
· Landscaping and covering of pathways.
It is an important part of an arsenic removal plant and filter.
