<p>A process for removing phosphate from water is disclosed. The process comprises: (1) forming a flocculate by adding an anionic polymer to water containing phosphate, a ferric compound, and chitosan; and (2) separating the flocculate from the water; wherein the weight ratio of chitosan to anionic polymer is 1:1 to 10:1; the weight ratio of chitosan to ferric compound is 1:2 to 1:200; and the weight ratio of chitosan to phosphate is 1:10 to 5:1. The process can be used to remove phosphate from treated effluent before it is discharged to natural waters.</p> |
