Conditioning and Dewatering Behavior of ATAD Sludges
(Virginia Tech, 2004-03-04)
Autothermal thermophilic aerobic digestion (ATAD) of sludge has been used to produce class A biosolids. With stringent EPA guidelines, more and more municipalities are looking to use this process for digestion of sludge. ...
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 ...
Factors Contributing to Trimethylamine Generation from Limed and Polymer Conditioned Sludges
(Virginia Tech, 2007-01-19)
Trimethylamine, (CH3)3N, (TMA), odors are often associated with limed and polymer conditioned sludges. This odor has a fishy smell and can be a nuisance to the community surrounding a wastewater treatment plant or land ...
Changes in Dewatering Properties Between the Thermophilic and Mesophilic Stages in TPAD Systems
(Virginia Tech, 2000-11-27)
Temperature-phased anaerobic digestion (TPAD) has become increasingly appealing in recent years due to the pathogen destruction capabilities of the system. However, there has also been concern about the dewatering properties ...
The Effect of Cations on Volatile Solids Destruction, Odors, and Dewatering in anaerobic digestion
(Virginia Tech, 2008-06-24)
The primary purpose of this study is to understand the effects of wastewater sludge feed cations on volatile solids destruction, odor control, and dewaterability. The role of influent feed cations and addition of chemical ...
