“…The respirometers used in anaerobic processes measure gas production as a gas volume determined either at a constant pressure or at a constant sample volume. Methane was selected as an indicator of the anaerobic process efficiency mostly due to its energetic properties, but also to its physical and chemical characteristics [15]. The test stand consisted of: x Respirometer for aerobic-anaerobic tests (AER-208, manufactured by CHALLENGE SYSTEM), x Water bath, x Heating/cooling unit, x Computer for online data processing (gas volumes measured every 2h).…”

“…Methanogenic activity was calculated based on the amount of methane produced from the sludge during the respirometric tests, and expressed in g COD CH4 g VSS -1 d -1 [15][16][17][18]. The maximum methane production and the R factor (as ml CH4 ·h -1 ) were determined based on the graphs showing the volume of methane produced per time unit.…”

Abstract.The article describes problems related to intensification of energy production at a wastewater treatment plant. The authors analyzed anaerobic co-digestion of sludge from both water treatment plant and sewage treatment plant. Water sludge is produced during coagulation, ozonation and backwashing of rapid anthracite filters. Its characteristic and properties depend on a raw water quality, treatment methods as well as types of chemicals used and their doses. According to the Polish Act of 4 December 2012 (Journal of Laws from 2013, item 21) the water sludge should be treated as hazardous waste. An alternative way to dispose water sludge and reduce its volume may be sludge reuse. The authors suggested a research methodology and analyzed the preliminary results, which showed that co-digestion of sewage and water sludge enhanced biogas production. The authors assume that the results of the study will provide a basis for development of methodology for sludge control and disposal.
