Aerobic Granular Sludge Technology

Technology that improves wastewater treatment while reducing lifecycle costs

Activated sludge has been a cornerstone of wastewater treatment since the early 1900s. Over the years, variations of the activated sludge treatment process have surfaced. These variants were efforts to improve treatment performance or reduce capital or operating costs. A new technology, known as Nereda®, uses aerobic granular sludge to meet all those criteria. Endress+Hauser and Aqua-Aerobic Systems spoke with Water Online about this new technology.
