Closed Cooling Water System Treatment and …

P rimary cooling at steam generating power plants and many other heavy industries is a critical aspect of operation, and upsets can cost a great deal in lost efficiency and production. But often overlooked are auxiliary closed cooling water (CCW) systems, which also serve vital functions. Failure of a closed system has the potential to shut down a portion, if not all, of the plant.
