Procedure

A sulfuric waste water containing 150 kmoles of sulfuric acid and 60 kmoles of metal sulfates (line 51) is treated with a sulfitic solution containing 82.5 kmoles of ammonium sulfite and 82.5 kmoles of ammonium bisulfite (line 52) in reactor (53); 165 kmoles of SO2 evolve and 97.5 kmoles of ammonium sulfate and 52.5 kmoles of ammonium bisulfate (line 55) are produced according to the reaction:
