Filtration media is widely used in municipal water treatment, and wastewater and effluent treatment processes. Read More

Plastic filter media - typically manufactured from polypropylene or PVC - is suitable for the biological treatment of sewage and industrial wastewater.

Structured media is self supporting and directs flows through defined horizontal / vertical channels, whereas random media replicates the free-form flows associated with aggregates.

Anthracite is a carbon-based medium that can be used in gravity or pressure filters to treat drinking water. It should be produced to BS EN 12909:2005 - 'Products used for treatment of water intended for human consumption. Anthracite.'

Blast furnace slag is a byproduct of steel production. Modern granulated slags have consistent chemical properties and those that conform to BS 1438:2004 can be used in biological percolating filters.

Filter sands should be free from impurities, and provide the the grain size, hardness and angularity values required for effective water filtration. Sands are often combined with anthracite in dual media filters. Filter gravels are also available.
