Abstract:
A multistage desalination process for treatment of seawater or salt wastewater. During initially processing the seawater or salt wastewater is treated to precipitate scaling minerals as phosphates including magnesium ammonium phosphate useful as a fertilizer. During the initial phase, ammonium phosphate and sodium phosphate are added to the seawater or salt wastewater followed by an addition of ammonia and a water-based charged solvent. After separating the precipitated solids, the cleaned seawater or salt wastewater is aerated and filtered to produce potable or otherwise usable water.

Claim (Index 1):
A seawater or salt wastewater desalination process comprising:\n performing a phosphate precipitation process, the phosphate precipitation process including adding a first mixture comprising ammonium phosphate and sodium phosphate to seawater or salt wastewater and mixing the first mixture and the seawater or salt wastewater; after mixing the first mixture and the seawater or salt wastewater, adding a second mixture comprising ammonia and a water-based charged solvent to the seawater or salt wastewater and mixing to produce a seawater or salt wastewater mixture having a pH of greater than or equal to about 8.5; performing a solids collection process to collecting precipitated solids from the seawater or salt wastewater mixture, the solids including, magnesium ammonium phosphate; after performing the solids collection, performing an oxidation process comprising aeration of the seawater or salt wastewater mixture, followed by filtration removal of solids produced during the oxidation process; and performing a final filtration process comprising microfiltration followed by nano-filtration of the seawater or salt wastewater to produce potable or usable water.
