Impact of the anaerobic digestion process configuration on the sludge dewaterability

Popis výsledku v původním jazyce

Anaerobic sludge digestion is an important tool for converting sludge into a renewable fuel-biogas. How-ever, digested sludge can also be used as a fuel, and a fundamental parameter determining the energy value of digested sludge is as effective as possible dewatering. The main aim of the presented study was to evaluate how the anaerobic digestion (AD) technology and post-treatment technology can affect sludge dewaterability. Two technological alternatives of AD were evaluated: mesophilic (MAD) and thermophilic (TAD). In addition, also the effect of post-aeration of digested was evaluated. The dewaterability was assessed using two methods based on centrifugation and filter pressing. Finally, the sludge cake concentration of total suspended solids (TSS) was compared. The results showed the difference in sludge dewaterability for the tested sludges: The sludge cake concentration was similar or slightly higher for MAD compared to TAD sludge. Post-aeration of digested sludge increased sludge cake concentration. © 2021, University of Chemistry and Technology, Faculty of Environmental Technology. All rights reserved.
