Abstract
The invention concerns a process for cleaning exhaust air containing biodegradable contaminants which are only slightly soluble in water. The contaminants are absorbed by a washing liquid containing activated sludge and at least one high-boiling solvent for the contaminants and are decomposed by the activated sludge. The solvent and the activated sludge are separated from at least part of the remaining washing liquid which is then drained off. In order to reduce significantly the amount of substances which are dangerous to the environment or to health in the washing liquid separated off, without making it necessary to take costly additional measures, it is proposed that the part of the remaining washing liquid be separated off by membrane filtration using inorganic or hydrophilated organic membranes. Silicone oil is a particularly suitable solvent for use in the process.
