RECOVERY OF HIGH-PURITY CALCIUM PHOSPHATE |
| abstract |
The present invention relates to a method for recovering high purity calcium phosphate from wastewater. In particular, the present invention relates to the precipitation of dibasic calcium phosphate dihydrate (DCPD) or hydroxyapatite (HAp). The DCPD and HAp obtained by the method comply with the European Commission Regulation No. 231/2012 establishing specifications for food additives. Thus, the high purity calcium phosphate obtained by the method of the invention may be suitable for use in the food industry. |
