Anaerobic digestion

Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process. AD stabilises the sludge biologically in the absence of air. In doing so, it reduces the amount of volatile solids by their conversion to a biogas (methane CH4, carbon dioxide CO2 and water H2O). The biogas then demands further processing for recovery and reuse of its methane content.

Anaerobic digestion − an introduction

Anaerobic digestion (AD) is the most extensively employed sludge stabilisation process and, as with most sludge and wastewater unit processes, the design and performance of AD depends on the feed characteristics. Professor Simon Judd explains.

Anaerobic digestion optimization through thermal hydrolysis pre-treatment

Pre-treatment of sludge by thermal hydrolysis upstream of anaerobic digestion is used to improve AD efficiency. A study looked at (pre-)commissioning data for a full-scale AD installation undergoing upgrading with TH to assess the basis for optimisation.
