Thermal destruction - oxidative

Oxidative methods for sludge thermochemical treatment comprise incineration, wet air oxidation (WAO) and supercritical water oxidation (SCWO). These processes convert the combustible organic matter to primarily carbon dioxide and water, along with other gaseous oxidised products present at lower concentrations, and a solid residue. These methods differ in terms of the operational temperature and pressure, the required feed sludge water content, and the nature and concentrations of gaseous and solid products generated.

Phosphorus recovery by sludge acidification and dewatering

A pilot-scale Danish study of phosphorus extraction from acidified anaerobic and aerobic sludge samples has revealed removal to be more effective from anaerobic sludges, even though the digested sludge alkalinity increases the total acid demand.
