PCT No. PCT/EP95/03481 Sec. 371 Date Mar. 7, 1997 Sec. 102(e) Date Mar. 7, 1997 PCT Filed Sep. 5, 1995 PCT Pub. No. WO90/07617 PCT Pub. Date Mar. 14, 1996The invention concerns a method of removing substances present in water, in particular halogen-oxygen compounds which remain in the water as residues of disinfecting or are formed as by-products of oxidative water treatment. According to the invention, the substances present in water are removed by catalytic reduction in the presence of hydrogen on a supported precious metal catalyst.
