Applications of shallow solar ponds in wastewater treatment

Technical Report ·
OSTI ID:6578035

The Shallow Solar Pond (SSP) has been developed as a means of supplying solar heated water for industrial and commercial use. Potential applications of the SSP in wastewater treatment are investigated. The key findings of this study are: the only near term application of SSP's which involves significant amounts of energy is that of heating anaerobic digesters. Because of the economies of scale, only large systems (greater than or equal to 1 acre) can be justified. The digester gas displaced by the SSP must be assigned a value close to that of conventional gaseous fuels. Sludge preheating, rather than digester maintenance heating, is the most cost effective use of SSP heat. In the industrial and food processing sector, there exists significant potential for using anaerobic processes to treat medium and high strength wastes.
