Treating water contg. ozone-consuming components

摘要

In processing drinking water, esp. table and mineral water,in which raw water contg. components which consume O2 e.g. heavy metal ions, and opt. halide ions, is ozonised with conversion of (part of) the components to a filterable form and filtration to give pure water, CO2 is mixed with the water before and/or with the O3.
