Utility
Cooling pond water treatment system
31 Jan 23
A method of increasing operational efficiency of a power plant includes determining an average rate of accumulation of scale-forming compounds in a cooling water source, directing water from the cooling water source having a first concentration of scale forming compounds through a treatment system to produce a treated water having a lower concentration of scale-forming components than the first concentration by operating the treatment system with operating parameters selected such that a rate of removal of the scale-forming components from the water in the treatment system is greater than the average rate of accumulation of the scale-forming components, directing the treated water back into the cooling water source, and circulating water including the treated water from the cooling water source through a cooling system of the power plant.
