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

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