Gravel provides essential support and flow distribution in filter systems through graduated layers ranging from 2-50mm. Larger sizes at the bottom prevent media loss while supporting even water distribution during operation and backwashing.

Well known for its hardness and durability, Garnet has a high specific gravity as well as its chemical and abrasive resistance makes garnet an ideal filter media. Garnet effectively removes fine suspended solids due to its angular shape and hardness rating of 6.5-7.5 on the Mohs scale. Its density allows for sharp separation in multi-media filters while requiring minimal backwash water. Chemically inert and non-metallic, it occurs in large sizes for support beds and smaller sizes for cap beds, allowing faster back flushing. Ask for specific sizes.

KDF®55 is designed for chlorine and heavy metals removal with bacteria and algae control applications.

KDF®85 is designed for hydrogen sulfide and iron removal applications.

Silica sand, a processed quartz mineral with a specific gravity of 2.65, provides consistent mechanical filtration through its uniform gradation and angular shape. Its chemical stability and durability make it a cost-effective, reliable choice for water treatment systems.
