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 ...

Biosolids obtained through the autothermal thermophilic aerobic digestion (ATAD) process exhibit greater polymer demand for dewatering than those obtained through conventional mesophilic aerobic digestion processes. An increase in ATAD retention time and operating temperature resulted in an increase in proteins and polysaccharides in solution, and this

Batch experiment was carried out in a simulated thermophilic aerobic digester to investigate the digestion process of one-stage autothermal thermophilic aerobic digester and to explore the sludge stabilization mechanism. Volatile solids removal was 38.4% at 408 h and 45.0% at 552 h.

Per- and polyfluoroalkyl substances (PFAS) have emerged as significant environmental contaminants due to their persistence, bioaccumulative properties, and potential adverse impacts on health and ecosystems. Water Resource Recovery Facilities (WRRFs) play a crucial role in the management of PFAS, given their widespread presence in consumer products and

ABSTRACT: A three‐facility, full‐scale pilot program was undertaken at three small wastewater treatment plants in British Columbia, Canada. The project concludes several years of investigation and one year of plant evaluations for sludge treatment using autothermal thermophilic aerobic digestion (ATAD). Process effectiveness was shown by demonstration

Increased legislative constraints have fuelled an interest in developing sustainable and economical methods for sludge digestion. Autothermal thermophilic aerobic digestion (ATAD) is a robust process that produces Class A biosolids from a wide range of organic sludge (e.g., animal waste, sewage sludge, food processing waste etc.).

An autothermal thermophilic aerobic digestion (ATAD) and its kinetics were studied for pretreatment of waste Klebsiella pneumoniae strains from 1, 3-propanediol (1, 3-PD) fermented product. The total suspended solids (TSS), pH value, Redox potential and temperature variation by self-heating were investigated, including the numbers of pathogens.

An evaluation of autothermal thermophilic aerobic digestion (ATAD) of municipal sludge in Ireland
Journal of Environmental Engineering and Science, 2007Autothermal thermophilic aerobic digestion (ATAD) is an exothermic process where sludge is subjected to temperatures greater than 55 °C and a hydraulic retention time of 6–15 days. Organic solids are degraded and the heat released during the microbial degradation maintains thermophilic temperatures.
