The chemistry of phosphate precipitate formation is complex because of complexes formed between phosphate and metals, and between metals and other ligands in the ,wastewater,. Side reactions of the metals with alkalinity to form hydroxide precipitates are another factor to be considered. The amount of metal needed to remove phosphorus exceeds the stoichiometric amount at the low levels at which phosphorus is present in a ,wastewater,…
