The first of a year-long series on water pollution addresses the need to find more energy-efficient ways to treat wastewater. As energy prices increase, engineers will develop treatment facilities that can operate during utility off-peak periods. Costly and energy-intensive secondary biological treatment can be improved by recovering energy from sludges which are thickened either by gravity or flotation. Recent interest in land disposal is based on reuse of the nutrients on low-cost land and reclamation of the water. Various schemes are proposed, i.e., trickling filters, rotating biological contractors (RBC), anaerobic digestion, and incineration or pyrolysis. Tables summarize the performance and energy consumption of these techniques under various conditions. (DCK)
