Biofil filter media.

With a surface area of 135m²/m³ Biofil has a spherical design, suitable for applications where larger or greater voidage is required.

With purpose-designed features, Biofil, in the Warden Biomedia filter range, is an excellent alternative to traditional mineral-based media and are ideal for improved performance in new wastewater treatment plants. Biological filter media of the relevant dimensions can replace all or part of the mineral-based media to improve system efficiency where it has become impaired by overloading. The surface textures of Warden Biomedia enable biomass or bacteria to adhere more effectively to reduce the loss of media due to installation procedures.

Modern plastic filter media eliminate problems relating to clogging and puddling associated with gravel, slag, and clinker filter beds. Traditional biofilters using stones, slag or coke can easily be clogged after some time of operation. Modern technical solutions allow very high reduction of biogenic compounds. Reactivation and modernization of old type biofilter treatment plants are much cheaper than reconstruction of the treatment plants...read more  

Bioball filter media.

Bioball has a spherical design and surface area of 220m²/m³. Bioball is a perfect solution when the surface area is more important than voidage.

With purpose-designed features, Bioball, in the Warden Biomedia filter range, is an excellent alternative to traditional mineral-based media and are ideal for improved performance in new wastewater treatment plants. Biological filter media of the relevant dimensions can replace all or part of the mineral-based media to improve system efficiency where it has become impaired by overloading. The surface textures of Warden Biomedia enable biomass or bacteria to adhere more effectively to reduce the loss of media due to installation procedures.  

Modern plastic filter media eliminates problem relating to clogging and puddling associated with gravel, slag, and clinker filter beds. Former biofilters using stones, slag or coke can easily be clogged after some time of operation. Modern technical solutions allow very high reduction of biogenic compounds.

Biopipe filter media.

Pipe shaped random filter media with internal and external fins and surface area of 600m²/m³.

The Biopipe is designed to provide a large protected surface area for the biofilm and optimal conditions for the bacteria culture when the media are suspended in water. A durable, rugged and highly efficient media for moving bed biological reactors (MBBR) and integrated fixed film activated sludge (IFAS) systems.  

Its innovative design creates a high percentage of protected surface area for microorganisms to adhere. In turn, this increases the overall biomass concentration and can reduce the tank volume required for wastewater treatment. Large openings allow for the wastewater to freely pass through the media which helps maintain a healthy and thin biofilm...read more
