Abstract: In this paper a new mathematical steady-state model specifically aimed at the design of biological phases in single sludge predenitrification systems is proposed. The model is based on the mass balance equations of four ...

Abstract: The dewaterability of sludge from two conventional activated sludge (CAS) and three membrane bioreactor (MBR)–based wastewater treatment plants is investigated prior to and after anaerobic digestion. The concentration and ...
