PAS - Model ORGUS - Biofilters - Brochure

Building compact in prefabricated concrete containers enables us to deliver biofilters that achieve outstanding removal efficiencies with less than 50% of the size of conventional biofilters. A pressure chamber, two filter containers and a rooftop are stacked on a single plenum. The mounting pressure chamber avoids short-circuiting of the air and ensures a homogeneous partition over the surface of the filter. For optimal treatment, the air flows from the pressure chambers in series through two layers of biomass (dual stage treatment).
