Water utilities dose phosphates to potable water for reducing aesthetic problems, inhibiting scale formation, and reducing corrosion. However, there are significant gaps in understanding due to proprietary nature of some phosphate chemicals. This article summarizes the current state of the science, provides operational guidance, and identifies knowledge gaps to improve phosphate chemical performance and avoid unintended consequences.
Water utilities commonly dose phosphates to potable water to (1) reduce aesthetic problems by sequestration, (2) inhibit calcium carbonate scale formation via threshold inhibition, and (3) reduce corrosion of lead or copper plumbing materials by forming protective pipe scales. Despite widespread use and increasing importance of phosphates, significant gaps in fundamental understanding still exist. This is partly due to the proprietary nature of some phosphate chemicals, causing experimental data and acquired knowledge for public water supplies to be considered trade secrets. Here, we summarize the current state of the science, provide operational guidance, and identify knowledge gaps regarding the use of orthoand polyphosphates. The goal is to empower water scientists to improve phosphate chemical performance and to avoid unintended adverse consequences.
