    The presence of phosphorus (P) in discharged wastewater can lead to water pollution events and eutrophication. Given the increasing consumption of phosphate (PO 4 3−) rocks, wastewater containing large quantities of P is deemed as a potential source of P recovery.Crystallization of P is an ideal way to recover P because of its simple design, ease of operation, high efficiency, and limited .

  • Crystallization: Definition, Process, Uses, Examples .

    Crystallization, or crystallisation, is the process of atoms or molecules arranging into a well-defined, rigid crystal lattice in order to minimize their energetic state. The smallest entity of crystal lattice is called a unit cell, which can accept atoms or molecules to grow a macroscopic crystal.
