Filter Media

Anthracite
Anthracite typically produces consistent improvements in turbidity removal because, in part, to more efficient solids loading. Low uniformity coefficient media also 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.

Green sand is used to remove iron, manganese and hydrogen sulphide from water resources. It is used alone or in combination with coal in dual media filtration systems.

Quartz sand and quartz silex 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. It is also used in the various glass industry for glass manufacturing.

Gravel and water filter pebble is composed of sub-angular, hard durable, and dense grains of predominately siliceous material. Extracted from a clean glacial deposit. Gravel and pebbles physical properties make it among the finest available in the world for water filtration applications. Our filter gravel is washed, clean dried, and screened to meet exacting specifications with strict adherence to quality control.
