Abstract: Limiting flux theory has become accepted in the design of secondary clarifiers, and has proven useful in the operation of existing activated sludge facilities. In this paper, the governing equations used to find the recycle ...

Abstract: The paper-manufacturing industry generates more than 90,000,000 t of sludge annually in the United States, the disposal of which is a complex environmental issue. Test burns of pelletized and dried paper-mill sludge were ...

Abstract: In recent years the advent of the anaerobic expanded bed reactor (AEBR) has made possible the treatment of wastewaters of comparatively lower strength than have been treated traditionally by anaerobic means. However, ...

Abstract: The design and operation of complex remediation projects can often benefit from an analysis from a systems perspective, that is one in which the various components of the system are viewed holistically, and a specific ...

Abstract: A significant potential exists to lower energy consumption and reduce sludge production by incorporating anaerobic processes into wastewater treatment trains. The specific treatment arrangement studied in this case is the ...
