Abstract

Anyang Bakdal underground WWTP treats 250,000 /d of wastewater. Sludge from wastewater treatment, food waste leachate, and septic sludge are treated by advanced anaerobic digestion (AAD) with thermal hydrolysis process (THP) as pre-treatment, demonstrating innovative compact and efficient sludge treatment. Design parameters and operational experience since 2016 are outlined in the first THP plant in South Korea for sustainable biosolids management for low carbon circular economy.
