Relative heat transfer rate data from experimental cooling tower tests and a field test will be used to show the effectiveness of various calcium phosphate dispersants in minimizing fouling.  Pitting corrosion rates obtained by potentiodynamic polarization techniques will be presented in addition to general corrosion rates obtained by linear polarization techniques.  The effect of molecular weight and polydispersity of dispersants will be discussed.
