A dynamic control system for aerobic granular sludge

WebFor instance, a SVI30 (sludge volume index) of 80 to 120 is considered appropriate for an activated sludge process and this value is usually lower than its SVI5. However, the SVI30 of aerobic granules could be around 47 and this value is usually similar to its SVI5. This indicates the excellent settling ability of aerobic granules.
