ABSTRACT:
An improved oxidation and photooxidation process for treating water containing an oxidizable contaminant. In one embodiment, the organic compound does not have an electron donating aromatic group. A stochiometric excess amount of a calcium salt is added to precipitate carbonate and bicarbonate ions contained in the water as calcium carbonate. The calcium carbonate is removed from the water and the filtered water is then subjected to an oxidation process. In another embodiment, the organic compound does have an electron donating aromatic group. Carbonate and/or bicarbonate is added so that the water has a stochiometric excess amount of carbonate and bicarbonate. The water is then subjected to an oxidation process.
