Hardness Control is a white dry powder Phosphate Boiler Water Treatment product used for the reduction of hardness in boilers. Hardness Control is highly soluble in water and It will precipitate calcium hardness as a non-adherent sludge.
A precipitant designed to eliminate scale deposits and lower the hardness of water in boilers with working pressure up to 60 bars.
It is used in conjunction with alkaline liquid to prevent calcium scale deposits. Both products are used in our standard boiler water treatment programs for low-pressure boiler systems (0-32 bar) and medium-pressure steam propulsion vessels (32-60 bar).

Effect of phosphate in boiler water
Boiler phosphate control
Phosphate/pH relationship recommended to control boiler corrosion. Different forms of phosphate consume or add caustic as the phosphate shifts to the proper form. For example, addition of monosodium phosphate consumes caustic as it reacts with caustic to form disodium phosphate in the boiler water according to the following reaction:
NaH2PO4+NaOH®Na2HPO4+H2O
monosodium phosphate sodium hydroxide disodium phosphate water
Conversely, addition of trisodium phosphate adds caustic, increasing boiler water pH:
Na3PO4+H2O®Na2HPO4+NaOH
trisodium phosphate water disodium phosphate sodium hydroxide
