Non-metal cooling water treatments have generally been classified by composition. That is, most programs fit either the category of "all organic" or "stabilized phosphate." This implies that those in the same class will perform in a similar manner. A performance evaluation of four non-metal cooling water treatments in identical laboratory tests has been completed. Two programs in each category were compared in pilot cooling tower tests designed to simulate common field conditions. The results show that the traditional classification system failed to predict the relative performance of individual programs within each category. Among the four programs tested, the best results were obtained with a newly developed all organic program. Field case studies have also shown results similar to those found in lab studies for the new all organic program.
