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 ...
Extracellular Polymeric Substances in Activated Sludge Flocs: Extraction, Identification, and Investigation of Their Link with Cations and Fate in Sludge Digestion
(Virginia Tech, 2007-08-01)
<p> Extracellular polymeric substances (EPS) in activated sludge are known to account for the flocculent nature of activated sludge. Extensive studies over the last few decades have attempted to extract and characterize ...
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 ...
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 ...
