ABSTRACT:
An apparatus for treating water includes a vertically extending contact vessel, wherein water is contacted with ozone, and a return vessel which contains a column of water of a sufficient height to drive water through downstream solids separation stages. Ozone is removed from the water and the rate of ozone injection is monitored and automatically adjusted so that no great amount of ozone remains in water entering the solids separation stages. The ozone is generated in elongated elements that are cooled by the process water and that are positioned to serve as a static mixer for such water.
