High Temperature Thermal Processes.

Since the early 1900s, high temperature processes have been used for combustion of municipal wastewater solids. The popularity of these processes has fluctuated greatly because of their adaptation from the industrial combustion field. In the past, combustion of wastewater solids was both practical and inexpensive. Solids were easily dewatered, and the fuel required for combustion was cheap and plentiful. In addition, air emission standards were virtually nonexistent. [ABSTRACT FROM AUTHOR]
