Trisodium Phosphate (TSP) - The Water Treatment Product

The main phosphate used to clean the boiler is trisodium phosphate, sodium hexametaphosphate, and sometimes an appropriate amount of sodium hydroxide and sodium carbonate is added, but the alkalinity can't be generally too strong. In addition, a low-foam surfactant wetting agent is appropriately added in order to increase the degreasing effect.
