Biotechnology - biofilter systems

Biofilter technology modular conception with the parallel horizontal and vertical order option for removing of scent and a wide range of other air pollutants.

Bio-filters operate o­n the principle of bio-film, which covers the particles of the material. Volatile pollutants are dissolved together with oxygen in the moistened bio-film and are metabolized by micro organisms under aerobic conditions. Such metabolites (CO2) diffuse through biological layer, are converted into the gas phase and are collected from the device.

Biological filters for cleaning of air are designed for volumes within the range of flow from 100 to 10,000 m3/hour, or in the case of cleaning of liquid 1-100 m3/hour.
