cooling systems. in the cooling process of a power plant, water can be either used or consumed, whereas in other power production related operations water is normally consumed. water ‘use’ indicates that the same volume of water that is taken from the source into the plant, is directed back to that source. water use takes place, for example, in,the cooling water handbook - buckman,cooling water systems, it provides a high level of thermal conductivity, the ability to absorb heat and transport it away . when we use water to lower the operating temperature of equipment or entire plants, it is called cooling water . industries such as power, pulp and paper, oil and gas, ethanol, steel, mining, leather and manufacturing
