"The innovative and alternative technology provisions of the Clean Water Act of 1977 (PL 95-217) provide financial incentives to communities that use wastewater treatment alternatives to reduce cost or energy consumption. Some of these technologies have only recently been developed and are not in widespread use in the United States. This document discusses the technical and economic feasibility of using one emerging technology, the Carver-Greenfield* (C-G) municipal sludge drying process, for municipal wastewater treatment facilities. The C-G process uses the principle of multi-effect evaporation and is primarily used in the food, pharmaceutical, and industrial wastewater treatment industries. The C-G process can dry aqueous solutions or slurries with a wide range of solids contents (4 to 45 percent). The C-G drying process appears to be a cost-effective, energy-efficient method applicable to the wastewater industry. Research and development for application to municipal wastewater solids drying has reached the point for full-scale implementation."
