Abstract

The use of biofilters was investigated for removal of tetrachloroethylene (PCE), trichloroethylene (TCE) and vinylchloride (VC) which biologically converted contaminants to chloride, water and carbon dioxide. The biological conversion of gaseous PCE and TCE was tested in laboratory under aerobic and anaerobic conditions using compost and sphagnum based biofilters. The filter matrices were mixed with three different sources of micro organisms which included contaminated soil, activated sludge and manure. The supplied gases and vinyl chloride were analyzed by gas chromatography on gas samples which were taken from reactors and at end of the trial all matrices were analyzed for pH and moisture content.
