Abstract
A process is presented for the treatment of wastewater containing non-volatile pollutants and volatile chemically oxidizable organic and inorganic pollutants. The process combines efficient evaporation to concentrate the non-volatile compounds and a catalytic oxidation reaction to convert the volatilized organic and inorganic pollutants. A condensate product may be obtained by treating wastewater according to the inventive process that is of distilled water quality and substantially free of minerals and organics.
