Hydrodynamic cavitation principle was applied to phosphate containing water and waste water. A 20% Calcium hydroxide slurry was applied before hydrodynamic cavitation to precipitate calcium phosphate by reacting calcium hydroxide and phosphate in water. A 70% reduction of phosphate in waste water is observed compared to controls runs using orifice plate and jet nozzle designs to produce cavitation. The jet nozzle design showed best results of for phosphate reduction in waste water. After cavitation calcium hydroxide, rich treated waste water was settled and then naturalized with carbon dioxide gas.
