Abstract
The phosphorus recovery from charcoal of sewage sludge by an incineration method was investigated. The charcoal of sewage sludge was mixed with alkali metal hydroxide and incinerated at 750 °C in aerobic conditions. The phosphorus was successfully recovered as an alkali metal phosphate from the incinerated ash through water extraction. The recovery rate of the phosphorus reached about 75% to 80%. The appropriate condition of the phosphorus recovery and composition of the recovered phosphorus were investigated.
