Aerobic sludge granulation at high temperature-low humidity for domestic wastewater treatment

With inoculum sludge from a conventional activated sludge wastewater treatment plant, a sequencing batch reactor fed with domestic wastewater was operated at 50 ± 1 "C and pH 7 ±, to study the formation of aerobic granular sludge (AGS)for simultaneous organics and nutrients removal with a compl...
