Document Description
The Encina Wastewater Authority (EWA) is proposing a demonstration project to evaluate technology that would improve their process for handling biosolids at the Encina Water Pollution Control Facility. Biosolids are produced from the sewage sludge that is separated during the treatment of municipal wastewater and treated to meet U.S. Environmental Protection Agency (USEPA) pollutant and pathogen requirements for land application and surface disposal. The demonstration project would use a technique called "pyrolysis" to reduce the mass of biosolids requiring disposal and to increase the production of biogas, a byproduct of the solids digestion process that is used to generate energy at the EWPCF. Pyrolysis is the process of decomposition of organic material at elevated temperatures in the absence of oxygen.
