The Biological Sludge Reduction by anaerobic/aerobic cycling
(Virginia Tech, 2010-03-29)
An activated sludge system that incorporates a sidestream anaerobic bioreactor, called the Cannibal process, was the focus of this study. A prior study of this process (Novak et al., 2007) found that this system generated ...
Management strategy of landfill leachate and landfill gas condensate
(Virginia Tech, 2012-08-27)
Studies were conducted to evaluate the impact of landfill leachate discharge on the operation of waste water treatment plants (WWTPs). Two aspects of interferences were found: one is UV quenching substances, which are ...
A study of multi-stage sludge digestion systems
(Virginia Tech, 2010-07-14)
Various combinations of multi-stage thermophilic and/or mesophilic anaerobic sludge digestion systems were studied to evaluate their solids reduction, odor generation after centrifugal dewatering and indicator organism ...
An Investigation into the Effects of an External Electron Acceptor on Nutrient Cycling at the Sediment-Water Interface of the Occoquan Reservoir
(Virginia Tech, 2012-02-06)
Water supply reservoirs are often subject to accelerated nutrient enrichment from urban sources. Cultural eutrophication due to such enrichment requires the development of efficient management and remediation strategies ...
