Reduction of the phosphate content in waste water from the preparation of metal salts of ascorbic acid 2-monophosphate |
| abstract |
A process for reducing the phosphate content in waste water from the preparation of salts of ascorbic acid 2-monophosphate comprises A. treating the waste water from the crystallization of the metal salts of ascorbic acid 2-monophosphate with an alkali metal or alkaline earth metal hypochlorite, chlorine or H2O2, and B. precipitating, at a pH of 9-12, the inorganic phosphate which has been produced from organically bound phosphorus and/or was present in the waste water, especially as calcium phosphate. |
