Cultivation and characteristics of aerobic granular sludge for simultaneous organics and nutrients removal performances at high temperature
With inoculum sludge from a conventional activated sludge wastewater treatment plant, a sequencing batch reactor fed with synthetic wastewater was operated at 50 ± 1 °C to study the formation of aerobic granular sludge (AGS) for simultaneous organics and nutrients removal with a complete cycle time...
