Abstract: Disclosed is a process for purifying an effluent containing acids such as phosphonic and phosphoric acids by the addition of CaO or Ca(OH).sub.2 in an amount ranging from 55-93 per cent by weight basis acids at a temperature of 35.degree. to 100.degree. C to a pH of 8 to 12. After removing the precipitated material, the effluent can be neutralized with CO.sub.2 gas. The precipitate can be calcined to tri calcium phosphate.
