Operational History

In operation, the system is entirely satisfactory. The cooling tower was not installed originally because heat loss through the system—due to the length of the lines and the surface area of the tanks—was considered sufficient. During most of the operating time, this was true. However, during summer when ambient surface air temperatures occasionally reach 110° to 115°F in this region, Joliet, Ill., heat loss was not enough to maintain comfort for personnel manning the spray nozzles in the plant. During such periods, return water temperature rose to 114°F for a few days. Therefore, a cooling tower was installed.

The sludge averages 50 to 60% solids, about the minimum water content for the sludge to slide easily from the discharge chutes into catch buckets.
