Solids Handling and Treatment Performance with Waste Activated Sludge from the Nereda® Aerobic Granular Sludge Process: Comparisons to Conventional Activated Sludge
Abstract
This paper presents a collection of results addressing solids yield, digestion, and dewatering performance of the Nereda® aerobic granular sludge (AGS) process. Data are drawn from bench and full-scale studies with emphasis on comparisons to waste activated sludge (WAS) from conventional flocculent activated sludge (CAS) processes. Collectively, bench and full-scale data show that solids yield, digestion, dewatering, and other aspects related to solids handling were generally comparable for Nereda AGS WAS and CAS WAS operated for biological nutient removal and/or treating the same wastewater stream. Thus, there do not appear to be significant solids handling impacts from potential full-scale implementation of Nereda. In many but not all cases solids handling results with AGS WAS were more favorable than those obtained with CAS WAS.
