| Abstract |
The feasibility of the extended aeration activated sludge process as a relatively economical and effective means of secondary waste treatment has been demonstrated in the laboratory and in the field. The process requires more consistent operation and maintenance than aerated lagoons and this is a disadvantage where costs are high and skilled operators are extremely scarce. The utilization of exposed aeration chambers for the extended aeration process is feasible. Earthen basins are also feasible for use where economic and construction conditions warrant. Effective solids separation is the key to successful operation of extended aeration facilities and is dependent on both the biological and physical aspects of the system. |
