Large-sized aerobic granular biofilm: stable biotechnology to improve nitrogen removal and reduce sludge yield
{{output}}
Three parallel sequencing batch reactors (control, small-sized polyurethane sponge (PUS) (3.0 mm), and large-sized PUS (10.0 mm)) were used to investigate aerobic granular biofilm (AGB) characteristics. Results show that 10.0 mm PUS facilitated rapid formation... ...
