Bohn Soil Media

The most important component of the biofiltration process is the filter medium. A properly constructed and maintained soil bed biofilter houses an active, thriving ecosystem. Ultimately, its effectivenessand that of your waste air treatment project-depends upon the integrity of the media supporting the ecosystem.

Other biofilter systems rely on media composed of compost or other organic materials. Soil media has a number of significant advantages over compost.

Most importantly, it is permanent. In addition, soil media naturally buffers pH, absorbs water easily, and sustains a consistent air flow.

To harness the natural biodegradation process, Bohn Biofilter blends native materials-soils local to the area-to create an activated soil mixture. Each mixture is adjusted for mineral content, permeability, particle size, and pH factors.

Bohn Biofilter's meticulous, scientific design assures an active and productive microbial environment. The company guarantees the effectiveness of each soil-bed installation.

Maintenance and operating costs are low-and remain low-throughout the unlimited lifetime of the soil bed. A Bohn soil-bed biofilter uses only nominal amounts of electricity and water.
