PERFORMANCE AND MECHANISMS OF EXCESS SLUDGE REDUCTION IN THE CANNIBALâ ¢ PROCESS
(Virginia Tech, 2005-03-30)
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 ...
Cations and activated sludge floc structure
(Virginia Tech, 2002-07-23)
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 ...
Effect of Solids Retention Time on Activated Sludge Properties and Effluent Quality
(Virginia Tech, 1998-08-26)
The effect of solids retention time (SRT) or sludge age on activated sludge properties and effluent quality was investigated using laboratory scale reactors. It was found that an increase in SRT resulted in an increase in ...
Distribution of Colloidal Material in Activated Sludge as Influenced by Cations
(Virginia Tech, 2004-06-07)
Activated sludge influent and effluent from five municipal wastewater treatment plants were analyzed to further elucidate the roles of aluminum, iron, and the monovalent to divalent cation ratio (M/D) on the influent and ...
Biopolymer and Cation Release in Aerobic and Anaerobic Digestion and the Consequent Impact on Sludge Dewatering and Conditioning Properties
(Virginia Tech, 1998-08-27)
Sludge dewatering and chemical conditioning requirements were examined from the perspective of biopolymer and cation release from activated sludge flocs. Both aerobic and anaerobic digestion processes were considered ...
