Boiler feedwater can be protected from corrosive conditions through coordinated phosphate/pH control treatment. Phosphate buffers the boiler water, reducing the chance of large pH swings due to the development of caustic concentrations. In phosphate treatment, excess caustic combines with disodium phosphate to form trisodium phosphate.Get Price
