Phosphate Hideout

Phosphate Hideout. When the concentration of phosphate in the boiler water is too high, phosphate will react with boiler scale forming iron and iron sodium phosphates or precipitate to form a solid phase on the hot boiler tube surfaces and elsewhere. This phenomenon is called phosphate hideout and it can result in changes of pH, as well as the
