Abstract: A greywater recycling system. The system is designed using flow control management and minimally-sized holding tanks allowing use of on-site greywater recycling in locations where conventional greywater recycling systems are unsuitable. Where conventional greywater recycling systems produce low-value recycled water suitable for use in irrigation, the system produces high-value recycled water suitable for use in other systems, such as cooling towers with minimal impact on the facility and changes to existing processes. By using higher capacity extraction, reducing the size of storage tanks, and returning permeate to supply the extractor, as needed, the system operates efficiently while with a greywater source producing a non-continuous flow of greywater being modular and compact.

Abstract: An energy conserving wastewater treatment system capable of being fueled by alternate fuel sources comprises a synthesis gas generator that produces synthesis gas from a fuel and an organic waste digester that produces biogas. A combined synthesis gas and biogas storage reservoir that is in communication with both the synthesis gas generator and the organic waste digester. At least one boiler is in communication with the combined synthesis gas and biogas storage reservoir.
