Patent ID: 7722775

Claim:
A method of destruction of volatile organic and inorganic compounds in wastewater, the method comprising: containing the wastewater in a tank; stripping the volatile compounds from the wastewater and into a circulating gaseous medium, by at least one stripping-chemisorption column operatively connected to said tank; pumping and circulating the wastewater by a pumping means through said at least one stripping-chemisorption column and said tank; oxidizing the volatile compounds in said circulating gaseous medium, for forming oxidation products, by an oxidation means; using a first heat regeneration means for preheating said circulating gaseous medium before oxidation of the volatile organic and inorganic compounds entering said oxidation means; using a second heat regeneration means for accumulating heat from and cooling said circulating gaseous medium exiting said oxidation means; chemisorption of said oxidation products of the volatile organic and inorganic compounds in said at least one stripping-chemisorption column by the wastewater.
