Abstract
Sewage sludge incineration is extensively practiced in European countries such as the Netherlands, Austria, and Germany, where legislative developments prohibit the direct spreading of sewage sludge on agricultural land. These and other countries opt for mandatory P recovery from the sewage sludge ash (SSA) from incineration since this type of ash has a very high phosphorous concentration (about 10% per weight). Since P is on the EU list for critical raw materials, this element should be recovered from the ash, but no technology is yet implemented for such recovery. This work focuses on the development of an electrodialytic method for the recovery of P from SSA.
