Abstract
This document provides a qualitative report on the status of a program for energy conservation in wastewater treatment. Analyzing the nation's energy requirements for wastewater treatment by process has shown that the wastewater- and sludge-stabilization processes accounted for more than 56% of the energy used for wastewater treatment in 1978. Advanced processes are projected to have the largest increase in energy of all treatment processes between 1978 and the year 2000. To promote energy conservation in wastewater treatment, DOE has sponsored a number of projects (either wholly or in part), including the following: demonstration of the anaerobic upflow (ANFLOW) bioreactor at Knoxville, Tenn.; assessment of digester-gas production and use in anaerobic-digestion facilities; study of the enhancement of anaerobic digestion by carbon addition; demonstration of water-hyacinth wastewater-treatment (WHWT) at Lake Buena Vista, Florida; and demonstration of unheated anaerobic contact stabilization (UACS) of sludge. These programs are described. 19 references, 22 figures, 29 tables.
