Calcium phosphate precipitates formed in primary, secondary, or tertiary treatment units will tend to redissolve at the lower pH values encountered in anaerobic digestion.
Wetprocess sulfuric acid acidulation is the most common technique for treating phosphate rock. Phosphoric acid is produced by the reaction of sulfuric acid with phosphate rock . Phosphoric acid, also known as orthophosphoric acid, is very often further concentrated by evaporating water and formation of superphosphoric acid.
Phosphate Rock. Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (38 percent available) and 48 percent calcium (as CaO).
