Latest Patents

One of Greenfield's latest patents is the "Combined activated sludge-biofilm sequencing batch reactor and process." This invention represents a third generation Sequencing Batch Reactor (SBR3) treatment process for sewage or wastewater. The SBR3 process utilizes a multi-stage and multi-sludge configuration that can handle either continuous or intermittent inflow of wastewater. Each stage of the reactor is designed with individually controlled continuous or alternating anaerobic, anoxic, and aerobic operations, which can include mixing and recycling from other stages. The configuration and operation of the reactor are tailored to meet specific treatment objectives and effluent discharge requirements. In the preferred embodiment, carriers are employed to facilitate the control of operating conditions.

Another significant patent by Greenfield is the "Method of operating a sequencing batch reactor." This method involves a cycle consisting of FILL, REACT, SETTLE, and DRAW periods, with the option of an IDLE period. The supply of feed to the reactor is distributed into settled sludge located at the bottom part of the reactor. This method also includes non-mixed periods during the FILL and REACT phases, enhancing the operational efficiency of the sequencing batch reactor.
