    2016-11-3 · This concentration can be experimentally determined by increasing the phosphate feed to the point where there is no further increase in the PO4 concentration in the boiler water. This is the equilibrium concentration and the normal boiler water phosphate maximum limit should be approximately one-half of this concentration.
