1. A method for treating wastewater and producing inorganic phosphorus, comprising:
(a) inducing a mixture of microorganisms containing phosphorus and magnesium to release phosphorus and magnesium to provide a treated mixture that includes phosphorus and magnesium; (b) subjecting the treated mixture to solids separation to provide a phosphorus- and magnesium-reduced mixture and an ammonia-containing, phosphorus- and magnesium-rich liquid; (c) conducting the ammonia-containing, phosphorus- and magnesium-rich liquid to an inorganic phosphorus reactor to provide inorganic phosphorus; (d) anaerobically treating the phosphorus- and magnesium-reduced mixture to provide an ammonia-rich, phosphorus- and magnesium-reduced product; and (e) conducting at least a portion of the ammonia-rich, phosphorus- and magnesium-reduced product to the treated mixture prior to solids separation in step (b). |
