[Improving the quality of bathing water by oxygen releasing substances]

The bath water of an indoor swimming bath of 25m length has been preparatory acc. to TGL 37780/02 and by procedings of flocculation-filtration-chlorination. the filter drain water (clear water) had been supplemented by 20...30 percentage hydrogen peroxide or potassium peroxide sulphate. The reaction with chlorine existing in surplus and hydrogen peroxide results in a spontaneous formation of nascinating oxygen. The occurring wet oxidation of contents substances of the bath water also with an increased frequentation of the indoor swimming bath results in reduced rates of CSVMn and chloramine. This fact can be explained by the concurring reaction between oxygen and chlorine. Because of its low expense, the forced decomposition of hydrogen peroxide could be an alternative for utilization of ozone in small bathes. Contrary to this the combination potassium peroxide sulphate/chlorine will not result in such a significant improvement of the quality of bath water.
