Dynamic analysis of a biofilter treating autothermal thermophilic aerobic digestion offgas
Journal of Environmental Engineering and Science, 2006There is little information to describe how a biofilter responds biologically and chemically to the dynamic loading of complex mixtures of contaminants that are present in autothermal thermophilic aerobic digestion (ATAD) offgases. This paper presents the results of a full-scale study that is the first stage in a longer project to evaluate the use of ...

Abstract This study deals with a problem for the sustainable operation of Autothermal Thermophilic Aerobic Digestion (ATAD) systems. The problem is presented as a design of heat integrated batch processes under uncertainties. Heat integration framework is defined and a respective mathematical model is discussed.

The Study of Sludge Characteristics for One-Stage Autothermal Thermophilic Aerobic Digestion Process
Advanced Materials Research, 2011One-stage Autothermal Thermophilic Aerobic Digestion was autonomously designed to treat municipal sludges. By the way of batch operation experiment, the influence of removal rates of volatile suspended solids(VSS), total suspended solids(TSS), auto-rise temperature, and COD concentration, volatile fatty acid concentration of sludge, were investigated ...

Autothermal thermophilic aerobic digestion (ATAD) has been observed to exhibit a greater polymer demand for acceptable biosolids dewatering when compared with conventional mesophilic aerobic digestion. Field studies indicated that an increase in thermophilic detention time promoted the release of proteins and polysaccharides from the biosolids to the ...

Despite their widespread use, our understanding of the microbial ecology of the autothermal thermophilic aerobic digesters (ATAD) used to dispose of sludge from wastewater treatment plants is poor. Applying both culture-dependent and molecular methods to two ATAD systems in Victoria, Australia treating different wastewaters revealed that their ...

Abstract Several researchers have identified the need to and the optimum operating conditions (OCs) of autothermal thermophilic aerobic digestion (ATAD). Our main hypothesis is that the optimum operating conditions have the potential to significantly improve the specific energy requirements of ATAD systems, and perhaps even to increase their capacity.

Efficiency of Autothermal Thermophilic Aerobic DigestionUnder Two Different Oxygen Flow Rates
Water Environment Research, 2014ABSTRACT: The objective of this research was to understand the influence of oxygenation at two different oxygen flow rates (0.105 and 0.210 L/L/h) on autothermal thermophilic aerobic digestion (ATAD), and on the overall performance of Dual Digestion (DD).
