RECOVERY OF WASTEWATER TREATMENT CHEMICALS FROM FLY ASH

Fly ash was investigated as a source for wastewater treatment chemicals. Through a sequential caustic/acid leaching process, portions of the iron, aluminum, and silica in fly ash were solubilized allowing for the recovery of these materials in a useable form. Synthetic additives derived from this process were evaluated as coagulants in wastewater treatment and as conditioners for sludge prior to mechanical dewatering.
