High levels of total dissolved solids, ammonia, phosphate and organic impurities characterize municipal wastewaters. This paper presents results of an in depth laboratory and on-site study investigating the use of tertiary treated municipal effluent as cooling water make-up. The corrosion, fouling and microbiological challenges unique to this water are analyzed and solutions presented. An analysis of the various components of the cost for treating this water is presented.
