Sewage sludge pretreatment by low thermal disintegration for better efficacy of sludge digestion process
Abstract
The wastewater water treatment plant (WWTP) sector and it is developing technologies strive to be implement circular economy. The methane production from the sludge digestion process constitute promising source of the renewable energy for WWTP and approaching circular economy assumptions. For this reason, the objective of the study was to examine the modification of sludge characteristics due to the low temperature pretreatment. The effect of this pretreatment was evaluated by various parameters, which showed the increase of volatile fatty acids concentration (VFA) (up to ~6g/L) and chemical oxygen demand (COD) value (up to ~15 g/L). Moreover, the disintegration degree (DD), which up to 54% confirm higher bioavailability of organic substances, which can be readily used by methanogenic bacteria. As a consequence a higher methane production during fermentation process was observed
