Phosphate stabilizing compositions |
| 摘要 |
This invention relates to phosphate stabilizing compositions comprising (a) polyaspartic acid, and (b) an anionic carboxylic polymer. The compositions effectively stabilize phosphates by inhibiting the formation of calcium phosphate scale. The invention also relates to a process for inhibiting calcium phosphate scale in water treatment systems.
