Biofiltration is an air pollution control technology that utilizes microorganisms that break down other volatile air pollutants contained in biological odors and waste air currents.

During the biofiltration process, the polluted air is pumped through the biological filter filler material. Foul odorous particles in the air are adsorbed onto the filter filler and absorbed by the water film.

BIOFILTRATION PROCESS

The use of biological air filtration processes, natural organic and inorganic compounds, biological reactions, oxidations, reductions and hydrolysis have been ensured in a wide range of microorganisms (bacteria, fungi, yeasts), which are capable of metabolizing.

The basic principle of biological filter process arises from the possibility of creating a suitable condition for the survival of microorganisms in terms of carbon and energy, oxygen, temperature, acidity, micro and organic substrate.

To achieve the biofiltration process, the fillers are moistened to form an aqueous film plate. The filter bed is absorbed and melted onto the soft and porous material forming the bed (peat, sawdust, fertilizer, and mixtures thereof), making the material to be treated and the bacteria on the surface of the matrix.

For areas with bad weather conditions, even when protective coatings are applied within the reaction chamber, controlling the biological process, the system may be completely open.
