Biofiltering is a process based on microorganisms and its role in reducing odour and other contaminants found in polluted air . A special film layer is used inside the product where the microorganisms anchor themselves around the content of the filter, where the polluted air is pushing through . Contaminants from the air are blocked by the filter and after microorganisms adsorb them into CO₂ and water . The process is safe, environmentally friendly and complex solution for odour degradation. VENTUS biofilters units are designed to treat airstreams and unstable biological parts from polluted air coming from wastewater treatment, plants, pumping stations, sludge, handling units, sewage storage, systems, etc . Apart from average filters biofilters are working with microorganisms and its outputs are biomass, water and carbon-dioxide . VENTUS biofilters are developed as air treatment systems where no maintenance is needed as living microorganisms need no operation.

Efficiency of the biofilter depends on the size of the content . The filter material adsorbs the odorous compounds or other air pollutants from the waste air stream . Compost, bark or peat products, heather, lava, etc . can also be found among the materials used as filters . We are working with shredded pine roots using special technology to increase its surface for more microorganisms and for more effective putrefaction . Low energy costs, stable forming process, less maintenance work, easily compostable components and 3-7 years life expectancy are all the features we can proudly say about our product. 

VENTUS G is developed for gullies and manholes. If there is odor problem with the canalization (combined sewer) VENTUS G solves it. It fits to the 600 mm manhole gratings. Let the air out from the canalization and allow the runoff water to the sewer through the system with the special flexible non return valve. The VENTUS G produced three different sizes 10, 20 and 30 m³/h.
