Abstract

A water treatment process is disclosed. The process comprises providing a water stream containing one or more soluble species capable of forming one or more sparingly soluble salts, adding an effective concentration of at least one antiscaling agent to the water stream, passing the water through one or more desalination membranes, to obtain a desalinated water permeate and further to obtain a concentrate supersaturated by one or more sparingly soluble salts and containing at least one antiscaling agent, adding an effective concentration of a ferric (Fe+3) ion into the supersaturated concentrate, and separating the precipitated salts from the concentrate to obtain a de-supersaturated water effluent. This effluent can be recycled or further treated in a secondary desalination stage.
