Abstract

In order to make a phosphorus recovery method, investigation of a phosphorus recovery from incinerated ash of sewage sludge through gel formation was carried out. Aluminum phosphate was recovered from ash of sewage sludge using acidic extraction. The recovered aluminum phosphate was dissolved using aq. NaOH solution. Dissolved aluminum phosphate formed a gel by addition of aq. sodium silicate solution. Sodium phosphate was recovered through gel formation followed by solid –liquid separation.
