Comparison of phosphorus recovery from incineration and gasification sewage sludge ash

2019-3-15 · incinerated ash of sewage sludge was mixed with sodium hydroxide or sodium carbonate, and treated at 750 °C to 900 °C in aerobic conditions. The phosphorus was successfully recovered as an alkali metal phosphate from the treated ash through water extraction.

Ash from mono-incinerated sewage sludge has high concentrations of phosphorus (7-10%), iron (10-15%), and aluminium (5-10%), but also contains unwanted heavy metals such as cadmium. The high content of metal has up until now created an obstacle for possible applications for the phosphate-rich ash.

This study aims to investigate the thermo-kinetics of high-ash sewage sludge using thermogravimetric analysis. Sewage sludge was dried, pulverized and heated non-isothermally from 25 to 800 °C at different heating rates (5, 10 and 20 °C/min) in N 2 atmosphere. TG and DTG results indicate that the sewage sludge pyrolysis may be divided into three stages.
