Aerobic Granular Sludge (AGS) developed the last two decades into a widely applied modern variant for centralized activated sludge WWTPs and implemented up to multimillion person equivalents plant scale. Goal of the workshop is to share current best-practices for AGS in large WWTP’s while facilitating dialogue, knowledge exchange and identification of potential beneficial future scientific & application developments. In the workshop, owners and designers of several large AGS WWTP across the globe, will share their experience and lessons-learned and show how AGS reactor design and overall plant integrating was tuned towards coping with specific challenges. These include minimal energy/footprint consumption, extensive nutrient removal, salinity fluctuations and future load/treated water quality adjustments. Also hybrid plant integration to augment parallel activated sludge plants will be addressed, as well as plant integration with downstream membrane filtration to operate as AGS...
