P-62 Using as the sludge hydrothermal treatment residue ammonia adsorbent

Abstract

The ammonia adsorption performance of hydrothermally treated solid residue was examined. The solid residue prepared in the different hydrothermal condition by using microwave reactor. Hydorothermal treatment temperature fix in 5min, but treatment temperature was changed at 453-513K. Adsorption temperature was also changed in 308 to 328K. The solid residue treated at high temperature adsorbed high ammonia amount, and high ammonia adsorption performance was obtained when the adsorption temperature was low.
