Abstract
The equipment for each stage is aligned along the axis of a common drive shaft powered by a single motor. The biological stages pref. utilise an aeration tank with rotary drums partly immersed in liq. to be aerated and turned by the common shaft which is coaxial with the drum(s). The axis of the drive shaft is pref. inclined slightly to the horizontal. A rotary scoop arm fixed to the drive shaft is pref. used to measure the liq. delivered into the aeration tank from a holding tank downstream of the screening and degreasing stages. Similar rotary scoop arms are pref. employed for sludge recycling and disposal of excess sludge. The plant combines the high capacity of the activated sludge plant with the low energy requirement of the percolating filter system.
