Power Plant Water Treatment. All thermal power plants produce waste heat as a byproduct of electrical energy. The cooling towers for US thermoelectric power producers use more than 70 trillion gallons of water yearly. Cooling water must be treated to meet each individual site's needs, which vary with the influent source water quality, type of ...

Chemical treatment of water inside the boiler is usually essential and complements external treatment by taking care of any impurities entering the boiler with the feed water (hardness, oxygen, silica, etc.). In many cases external treatment of the water supply is not necessary and the water can be treated only by internal methods.

Water can leave the power plant in three ways: (1) evaporated in the flue gas, (2) as discharge streams, (3) as part of other products such as slag. The amount of water lost in the flue gas is the total amount of water suspended in the flue gas minus the amount of water formed in the combustion process.
