Why do water systems add phosphate to drinking water? What are …
网页2024年2月23日 · Public water systems (PWSs) commonly add phosphates to drinking water to prevent the release of metals in drinking water. Orthophosphate is most commonly used for lead and copper control. Polyphosphates sequester iron and manganese to prevent discolored water but are not effective to control lead and copper.
Orthophosphate - an overview | ScienceDirect Topics
网页Phosphorus in its simplest form, dissolved orthophosphate, is taken up by photosynthetic organisms at the base of the marine food web. When phosphate is exhausted, organisms may utilize more complex forms by converting them to orthophosphate via enzymatic and microbiological reactions.
