Title: Discovering the Innovations of Inventor Perry Schafer
Introduction
Perry Schafer is a notable inventor based in Sacramento, CA, who has made significant contributions in the field of wastewater treatment. With a total of two patents to his name, Schafer has developed innovative processes aimed at improving the efficiency and efficacy of sludge treatment.
Latest Patents
Schafer's latest patents focus on advanced methods for treating raw sludge. One of his innovations, titled "Method for treating raw sludge including a simultaneous or pulsed aerobic/anoxic digestion process," introduces an improved sludge treatment process that encompasses anaerobic digestion followed by post-mesophilic aerobic and/or anoxic digestion. This method allows for the anaerobic step to be executed under either mesophilic or thermophilic conditions. Furthermore, the subsequent aerobic/anoxic digestion can employ simultaneous, sequential, or pulsed conditions, enabling flexibility in treatment approaches. An apparatus designed for this improved sludge treatment may consist of a single digester capable of performing both anaerobic and aerobic/anoxic digestion, or it may utilize multiple digest reactors.
Another of Schafer's patent innovations is the "Biosolids flow-through thermophilic treatment process." This method involves continuously pumping raw sludge into a first digester where it is treated at specific temperatures ranging from 51°C to 60°C. The treated sludge is then transferred to a batch tank for further anaerobic treatment at slightly elevated temperatures. This treatment method ultimately allows for the disposal of the treated sludge as a Class A biosolid.
