Název v původním jazyce
Impact of the anaerobic digestion process configuration on the sludge dewaterability
Popis výsledku v původním jazyce
Main aim of presented contribution was to study how the anaerobic digestion (AD) technology and post-treatment technology can affect the sludge dewaterability. Two technological alternatives of AD were evaluated: mesophilic (MAD) and thermophilic (TAD). In addition also the effect of postaeration of digested was evaluated. The dewaterability was assessed using two methods based on centrifugation and on 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 in comparison with TAD sludge. Postaeration of digested sludge brought the decrease of the final amount of dewatered sludge thanks to decrease of the TSS concentration and thanks to increased sludge cake concentration.
