Abstract
Process for microbiological purification of halogenated ethylenes, comprises contacting the halogenated ethylenes to be treated in an aerobic bioreactor with a strain of bacteria which decomposes halogenated ethylenes and which has been adapted to growth and provision of energy using ethylene as carbon- and energy source. USE - The process is used in the purification of water and/or air containing cis-1,2-dichloroethylene and/or vinyl chloride, particularly where the contaminated material to be treated is ground water or air. ADVANTAGE - The process is simple and economical to operate, allows complete decomposition of halogenated ethylenes, and is effective in purifying water or air containing high concentrations of cis-1,2-dichloroethylene or vinyl chloride up to 100 mg/l.
