Treatment of wastewater into drinking water using ozone

摘要

A process is shown for treating wastewater or contaminated raw water into drinking water, where, after the water has been pre-cleaned, ozone is added to the water in an ozone reaction tank (3) and a reaction between ozone and impurities in the water takes place, the water then passing through a membrane filter (4) is fed with ceramic membrane. The fact that in the membrane filter (4) in front of the membrane and / or in the line (23) between the ozone reaction tank (3) and the membrane filter (4), in particular immediately in front of the membrane filter (4), ozone can be added to the water again bromate formation can be reduced without a catalytic membrane.
