Biofiltration

Simdean have designed and installed biofilters to treat exhaust gas volumes up to 100,000 m3/h.

Biofiltration is a relatively new pollution control technology. It is an attractive technique for the elimination of malodorous gas emissions and low concentrations of volatile organic compounds (VOCs). The most common style of biofilter is essentially a large container filled with media. Some can be as big as a basketball court or as small as one cubic metre. A biofilter’s main function is to bring microorganisms into contact with pollutants contained in an air stream. The housing that makes up this biofilter contains a filter material, which is the breeding ground for microorganisms. These microorganisms live in a thin layer of moisture, the “biofilm”, which surrounds the particles that make up the filter media. During the biofiltration process, a polluted air stream, generally containing volatile organic compounds (VOC’s), is slowly exhausted through the biofilter and the pollutants are absorbed into the filter media. The contaminated gas is diffused in the biofilter and adsorbed onto the biofilm. This gives microorganisms the opportunity to degrade the pollutants and to produce energy and metabolic byproducts in the form of CO2 and H2O

Simdean have designed and installed biofilters to treat exhaust gas volumes up to 100,000 m3/h.  In addition we are able to supply bio-trickling filter and bio scrubbers
