Phosphorus Treatment and Removal Technologies

WebMany wastewater treatment plants use chemical phosphate precipitation to remove phosphorus from wastewater. However, phosphate loads can fluctuate, making optimal precipitant dosing difficult. If the dosage is too low, the strict phosphorus limits will not be met. In contrast, overdosing means a higher volume of sludge and thus higher disposal ... WebMeasuring phosphate in wastewater effluents is critical to maintaining a healthy ecosystem and protecting wildlife. Many areas have strict discharge limits for phosphates to protect the ecosystem that receives this water. Besides protecting the ecosystem, failing to monitor and control your phosphate levels can also lead to violations and fines.
