Abstract: The present invention relates to a device, particularly a nozzle, for treating waste water, said nozzle having an outer tube and an inner tube. An intermediate space is formed between the outer tube and the inner tube and said intermediate space between the outer tube and the inner tube is divided into at least two chambers in the longitudinal direction of the tubes. The inner tube tapers in the longitudinal direction and then widens again and has at least one opening into each chamber at the constricted area. On the inner side of the inner tube and/or in the interior thereof, the device preferably has a catalyst. The present invention further relates to a method for oxidizing polluted waste water and a system for performing the method.

Abstract: A textile treatment composition which comprises; a textile binding agent which forms a chemical bond with the outer layer of the textile according to the formula (Ia): ##STR1## and, a barrier agent which forms a chemical bond with the textile binding agent and which increases the surface tension of the textile. Methods for treating textiles with the treatment composition, and kits comprising the components are also provided.
