  • Water Research Center - Phosphate in Water

    Poly forms are used for treating boiler waters and in detergents. In water, they are transformed into orthophosphate and available for plant uptake. Organic phosphates are typically estimated by testing for total phosphate. The organic phosphate is the phosphate that is bound or tied up in plant tissue, waste solids, or other organic material.Learn More

  • Determination of Salt Component Concentrations in Boiler

    Jul 17, 2019 · An important purpose for the automation of the boiler water's chemical quality control in drum-type power boilers is to measure the concentration of trisodiumphosphate and control its metering into the boiler water [1, 2].Current regulations [3–5] establish strict requirements for the quality of feedwater and boiler water and decrease the range of allowable phosphate concentrations.Learn More

  • Calculating Boiler Chemical Requirements – Water

    Jun 26, 2017 · Assume boiler operates at 10 cycles of concentration, and the residual boiler water alkalinity, M, is 250 ppm. This is the amount of phosphate required to react with 30 ppm calcium ion. 64 ppm disodium phosphate divided by 120 equals 0.533 lbs disodium phosphate per 1000 gallons treated water.Learn More
