Ozone has traditionally been used in the U.K. for the removal of organic colour from upland raw waters concomitantly converting the composite organic compounds to lower molecular weight, more biodegradable organic acids. However, ozonation has substantially no effect on the dissolved organic compound concentrations and, although the organic removal efficiencies of GAC filtration processes are generally...
