Water Treatment for Corrosion Control Phosphate Inhibitor Addition. This method of corrosion control is based on the theory that the addition of phosphate to a finished water will result in the formation of low-solubility lead-phosphate complexes on interior pipe surfaces.


Phosphates are plant nutrients that can also be a pollutant. To thrive, algae depends on phosphates. The higher the level of phosphates present in water, the greater the risk of algae growth. Phosphate levels dictate how fast the algae can bloom. And this can create a nightmare situation for pool owners.

 · The uptake of VFAs ends up releasing phosphate into the surrounding water. Once in an aerobic environment, the PAO organisms use the stored VFAs for energy and uptake the free phosphorus in the water and store it as polyphosphate inside the cells. PAO organisms do not develop unless their ecological niche exists in the system.

Boiler Water Treatment Phosphate compounds are common additives for boiler water treatment. Phosphate compounds react with any remaining hard water compounds to create a soft sludge that is eliminated through blowdown. Trisodium phosphate is the most common compound for lower pressure boilers. Phosphates also scavenge (or remove) any remaining

Phosphate Treatment

Although phosphate treatment is effective for lead, phosphate dosing of waters with high alkalinity and low pH may slightly increase cuprosolvency. Orthophosphates, along with polyphosphates, can also be used as corrosion inhibitors to reduce the risk of supplying ''red water'' from corroding iron pipes.
