85-07: Low T.D.S. Makeup Water -- A Problem?

Discusses solutions to fouling and corrosion problems associated with a water supply with low total dissolved solids (TDS). Historical data indicated that the water was clear and contained less than 100 mg/l dissolved solids, an ideal source for cooling tower makeup at a 400-MW electric generating station in Oklahoma. In fact the water was low in TDS but high in colloidal and dissolved organic material that is heat sensitive and fouling in nature.
