Studies were conducted to determine the role of bioflocculation in the activated sludge unit processes. Laboratory and full-scale studies revealed that bioflocculation is important in determining settling, dewatering, ...

Bioreactor landfills have become a feasible alternative to the typical â dry tombâ landfill. By recirculating leachate and/or adding additional liquid wastes, bioreactor landfills operate to rapidly degrade and transform ...

Laboratory microcosm experiments were conducted to assess the potential for biostimulation and bioaugmentation as source reduction measures in support of a monitored natural attenuation remedial strategy at Naval Amphibious ...

The objective of this paper is to evaluate the effectiveness of leachate recirculation and bioreactor landfills at enhancing biodegradation, and to optimize the operation of a bioreactor. Waste Management has been examining ...

In order to study the performance and mechanisms of excess sludge reduction in the activated sludge that incorporates the Cannibalâ ¢ Process, laboratory activated sludge systems incorporating an anaerobic bioreactor into ...

The effect of high organic liquid wastes on the overall performance of anaerobic bioreactor landfills is not known. In this study three different liquid wastes were added to mix of office paper, newspaper, cardboard and ...

This research was designed to investigate the effect of cations on activated sludge characteristics and also to determine their influence on digestion performance. For this purpose, cations in solution and in floc were ...

This was a study undertaken to investigate municipal solid waste (MSW) landfill stability parameters and landfill leachate properties to determine how solid waste and leachate characteristics can be used to describe ...

NITRIFICATION OF LANDFILL LEACHATE BY BIOFILM COLUMNS by Matthew M. Clabaugh J.T. Novak, Chairman Department of Environmental Engineering (ABSTRACT) Landfill leachate characteristics vary depending on the operation type ...

The arsenic maximum contaminant level (MCL) for drinking water is likely to be lowered sometime in 2001 or 2002. If the MCL is lowered, it is speculated that there will be stricter limits imposed on the disposal and ...
