THE SCALE METER: A NEW METHOD FOR DETERMINING THE CRITICAL PH OF SCALING

A new understanding of the Saturation Index is presented which leads to the concept of a critical pH, the true pH of scaling. The critical pH is about 1.7 to 2.0 pH units higher than the pH of saturation predicted by the index. The method of determining the critical pH is described as a continuous controller which utilizes this theory. The application of the controller to cooling water systems is described for several chemical treatment programs, and controller results are given.
