A process for removing contaminants from waste liquid e.g. water comprises removing contaminants such as benzene, toluene, chlorobenzene, methyl chloride, trichloroethane, vinyl chloride and xylene from waste liquid by stripping the waste liquid gas e.g. air, nitrogen, carbon dioxide, propane. The gas may be passed into an incinerator for combusting the contaminants. The stripping of the waste liquid preferably takes place in a packed column. |
