Subsequently, photometric measurements are taken at all tapping points (cold and hot water) at regular intervals, until the disinfectant solution without food can be found everywhere at all sampling points. The taps are closed again after the yellow disinfectant solution has been tapped, then opened every few minutes. Occurs then the disinfectant solution then, in part only after repeated repetition, without consumption from a tap, it can be concluded that the system has no more food, so the ingredients of the water like microorganisms and biofilm have reacted in the line with the chlorine dioxide and thus oxidized (removed at best).
  • the above-described flushing method in all drinking water systems applicable, for example, on ships, boats, in vehicles, trains, aircraft, but also drinking water tanks or power lines, sewer systems, service networks, cooling systems, etc ..
  • the disposal of the rinse water can easily via the sewer into the Drains take place. Even at high residual concentrations of chlorine dioxide, the water poses no danger to the sewage system. Residual amounts of oxidizing agent are quickly consumed there. Wastewater treatment plants are not affected. After consumption, chloride and sulfate are formed in very small amounts.
