Abstract

The aim of our article is to expose the problems around the concentration of urea and ammonium in bathing waters. The statements are based on the German DIN norms 19 643-1 from 1997. Severe requirements about bound chlorine concentrations are introduced, and it is explained why ammonium and urea determinations in chlorinated bathing waters have been crossed off the list. The comparison of the essential parameters between Slovene and German standards is given. Finally, some methods of dechloramination are presented.
