Evaluation of influent microbial immigration to activated sludge is affected by different-sized community segregation

Evaluation of influent microbial immigration to activated sludge is affected by different-sized community segregation

Abstract Activated sludge (AS) microbial communities were analyzed for seasonal variation, a disturbance-recovery event, and separated small aggregates (SAG) to study the influent immigration effect using both neutral immigration model and mass-balance model with operational parameters. SAG differed...
