ABSTRACT:
Cooling tower water is analyzed for pH and electrical conductivity. In response to the pH measurement, acid addition is made periodically (intermittently) so that fluctuations in pH during acid addition are minimized. The conductivity measurement, which relates to salts concentration, controls periodic (intermittent) blowdown of water having high salts concentration so as to minimize waste of water and water additives during blowdown.
