A four-tower water treatment test facility was built for the study of corrosion in copper condenser tubes. A two-by-two factorial experiment was run using phosphate treated water at two levels of water velocity and two water temperatures. The system was operated continuously for ninety days after which the tubes were removed for inspection. After being split open, the tubes were visually inspected for pitting corrosion. Pits were found in the tubes from the two towers operating at low water velocity; these pits were more severe in the high temperature units. Silt deposits were much less in the low temperature, high velocity unit than in the other units. Results indicate it is possible to simulate plant conditions in the laboratory. 7.4.2
