Phosphorus treatment wastewater
WebChemical precipitation is a very common and well-known technology, especially for phosphorous removal in municipal wastewater treatment. It involves the addition of metal salts of aluminum, iron, or calcium to alter the physical state of dissolved solids and facilitate their removal by sedimentation. WebApr 12, 2024 · Abstract—The microbial diversity and community structure of activated sludge in the biological treatment units of five municipal WWTPs and two industrial WWTPs were studied. The results showed that industrial WWTPs had the lowest diversity and abundance of activated sludge microbial communities, indicating that industrial …

WebPhosphorus almost always is bound to oxygen as phosphate. It can be found as a single ion with a –3 charge, commonly called “orthophosphate.” Phosphate ions can form a chain called “polyphosphate.” Phosphate also may be bound to an organic molecule as organic phosphorus. Untreated wastewater contains phosphorus in many forms. WebAbstract.
