Aerobic Granular Sludge: Perspectives for Excess Sludge Management and Resource Recovery
Chemie Ingenieur Technik, Volume 95, Issue 12, Page 1881-1896, Dezember 2023., 2023 Abstract Aerobic granular sludge (AGS) technology is gaining increasing interest globally. However, several aspects are still challenging its installation, as the integration into existing municipal wastewater treatment plants. The operation of AGS units in continuous flow mode could facilitate that integration; yet has only been experienced at lab and
