An intensive biotrickling filter technology has been developed in Moscow Bakh Institute of Biochemistry in cooperation with Chemviron Carbon which enables degradation of toxic compounds by specially adapted, highly active strains of micro organisms, immobilized on an innovative artificial carrier in a specially engineered system. The degradation efficiencies achieved are generally in the range of 80 to >99% for VOC concentrations of up to 1,500 mg/m3 and contact times of 2 to 20 seconds. The technology is applicable both for VOC and odour control that is illustrated by two case applications: removal of dichloromethane at industrial facility in UK and pilot deodouration studies at Moscow water works. A long-term sustainable performance of bioreactors operating at 3-4 s contact time and efficiency of 85-95 % has been achieved. High throughput characteristics and efficiency of developed biotrickling filters enable a reduced site area, whilst minimizing overall capital and operational costs.
