WebJan 1, 1996 · Thus, chemists usually operate phosphate treatment programs on a coordinated or congruent basis. In these applications, adding di-sodium phosphate to the system maintains the solution`s sodium-to-phosphate molar ratio below 3:1. Figure 3 shows the recommended guidelines for a coordinated phosphate program. Maintaining … WebCoordinated pH-phosphate control was introduced in 1942 as a method of protecting boiler tubes from "caustic embrittlement," as well as protection from the effects of condenser in-leak age, primarily water hardness contaminants. Boiler sy stems containing copper alloy s should hav e a condensate/feedwater pH within the range of 8.8 - 9.2.
