key dissimilarities between thermophilic and mesophilic anaerobic digestion of waste activated sludge (was) were experimentally studied in this research. typical was with total solids (ts) concentrations of 30 and 60 g/l were digested anaerobically in a batch digester at mesophilic and thermophilic temperatures. solids reduction, total cod changes, the production of different volatile fatty aci...

In this study, extracellular polymeric substances (EPSs) producing strain was isolated from municipal wastewater sludge (MWWS). Growth profile and the EPS production by Cloacibacterium normanense using wastewater sludge as raw material in shake flask fermentation for 96 h were investigated. The highest concentration of S-EPS (13.0 ± 0.8 g/L) and C-EPS (0.3 ± 0.1 g/L) were attained at 48 h of fe...

Mechanical dewatering is a key process in the management of sewage sludge. However, drainage efficiency depends on number factors, from type and dose conditioning agent to parameters device. The selection appropriate methods sludge task laboratory work. This work can be accelerated through use artificial neural network (ANNs). paper discusses possibilities using ANNs predicting physically condi...

This work experimentally elucidates the effects of ultrasonic treatment on the physical, chemical, and biological characteristics of a waste-activated sludge. A critical ultrasonic power level exists above which, accompanied with the release of divalent cations from the sludge body, the floc structure effectively disintegrated, microbial level acceptably disinfected, and particulate organic com...
