Better efficiencies can be obtained by providing slow revolving stirrers, particularly with gassy sludge.

For best performance, a good rule-of-thumb is to maintain the blanket of 0.6 m (2 ft) or less at all times. A common operational target for RAS flow rates is to maintain flows between 50% and 150%
Introduction To Activated Sludge Study Guide
dnr.wi.govSludge age is the theoretical length of time a particle of activated sludge stays in the treatment plant, measured in days. In an activated sludge plant, sludge age is the amount (lbs) of mixed liquor suspended solids divided by the suspended solids, or excess cell mass, withdrawn from the system per day (lbs per day of waste activated sludge).
CHAPTER 6 WASTEWATER TREATMENT AND DISCHARGE
www.ipcc-nggip.iges.or.jpThe most common wastewater treatment methods in developed countries are centralized aerobic wastewater treatment plants and lagoons for both domestic and industrial wastewater. To avoid high discharge fees or to meet regulatory standards, many large industrial facilities pre-treat their wastewater before releasing it into the sewage system.
