Description

Biofilters are developed to collect and purify storm- and wastewater and represent a promising system for storm water treatment. Bacteria and microorganisms are located on a filter medium, which often consists of sand or granular activated carbon. The biofilm of bacteria degrades nutrients and contaminations in the wastewater that is piped through the filter material.
