Abstract

A method for treating contaminated liquids in a flow by ozone, wherein the ozone is fed in gas form into the flow at one point and then is mixed into the flow in stages by mixers following one another in the flow direction, so that an absolute quantity of introduced ozone increases after each mixer until a feed efficiency of more than 95 percent is reached.
