Introduction & Significance

Advanced anaerobic digestion (AAD) is a sustainable way to treat sewage sludge (SS) while addressing circular economy for biosolids management. Several utilities worldwide have adapted AAD. In Poland, there are currently over 140 municipal AD installations, which have over 120 biogas power plants. A case study of Tarnow wastewater treatment plant (wwtp) has been presented here, which installed a thermal hydrolysis process (THP) prior to AD, to generate higher quantity of biogas for energy purpose, thus becoming one of the few AAD installations in Poland. The drivers for AAD for Tarnow was to achieve asset optimisation, reducing carbon footprint while addressing circular economy.
