The primary demand for water in a power plant is for condenser cooling. The methods used for condenser cooling in the power plant are once-through, evaporative cooling, and dry cooling. The quantity of water required for a cooling tower is determined by a parameter known as the cycles of concentration (COC). Therefore, one of the ways to save water is to increase the number of COC. Unfortunately, this increases the potential for scaling and corrosion because of the resulting higher levels of dissolved solids.
