Mining Phosphate from Wastewater: Treatment and

In recent years, treatment and reuse of phosphate mining wastewater have been gaining considerable attention. The mining of phosphorus from raw phosphate rock (PR) can lead to air pollution, eutrophication in receiving waters, land degradation through phosphogypsum (emitted by stacks near the mining sites), and soil contamination.

Phosphates in Wastewater | Products Finishing

A. The phosphorus occurring in industrial and household wastewater is almost entirely as phosphates. Phosphates are essential for plants and animals, but too much phosphate contributes to eutrophication—fertilization—of our streams, rivers, and lakes, allowing algae to grow so abundantly that it dies for lack of light; the decomposition of the algae uses the water’s dissolved oxygen ...

Orthophosphate in Wastewater | EBS

2021-3-1 · Phosphorus, as soluble orthophosphate, is a critical nutrient in all biological processes, including activated sludge treatment. It is utilized by bacteria in making energy (ATP molecules) and in creating phospholipid bilayers, their cell structure. This procedure is to determine the ortho-phosphate content of wastewater samples from various points in the system.

Calcium Phosphate Precipitation in Wastewater

Values of residual dissolved phosphate in wastewater precipitated with lime at pH values between 9.5 and 11.0 could be predicted to within 25% of their experimental values if these predictions were based on the initial concentrations of dissolved lime rather than on the total lime added and if a correction for calcium complexation was made.
