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.

Container sized biofilter system from PURECO. Our container is fully equipped and ready for automatic operation. The body of the filter unit is built up from special plastic wall (UV stable). The wall is strong enough to handle the loads from the
operation and transport, but light to be handled without crane. The system is constructed up from three main elements, the first one is the washer tower, that prepares the airstream for the second biological stage, removes the solids and
sets the humidity. The second stage is the air purification section with biomass filter media. Third part is the operator room with the control cabinet, from here the operator can set up everything. The largest container is truck sized with the
treatment capacity of 5000 m³/h, with the combination of the units we can reach higher treatment capacity. The purified airstream can be 2000 m³/h with multiplied items it can expanded by 50 000 m^3/h or more
