While land application of both Class B and Class A wastewater biosolids is widely recognized by private companies and government regulatory agencies as a beneficial use and as a highly desirable practice, the processes used to achieve the preferred, non-restricted use, Class-A biosolid status are typically very expensive. A continuous, plug flow, Class-A biosolids producing process, Eco-therm, has been developed which is both commercially and environmentally viable, utilizing the energy of the biogas from an anaerobic digester to pasteurize the sludge prior to the digester. The continuous flow design simplifies the process, enabling the hydraulic and mechanical operation to be much less expensive than non-continuous flow designs.
