  • Patent number: 11724951
    Abstract: A decentralized wastewater reuse design utilizing trickling filter (TF)-based aerobic bioreactors responds to the growing need for efficient energy usage per gallon of wastewater treated and/or pound of biological oxygen demand (BOD) removed from processed influent. A facility based on this design is able to adjust power consumption as needed due to external factors, such as utility rate scheduling, grid availability, and/or renewable power sources, without compromising effluent quality performance or increasing energy intensity. The facility improves on past TF applications by overcoming physical hydraulic constraints and expanding the capacity for both aerobic nitrification and anaerobic denitrification throughout the system.

  • Publication number: 20230091027
    Abstract: An intelligent sewage system designed for use in municipalities around the Wildland Urban Interface incorporates a decentralized network of wastewater treatment units to process wastewater from a plurality of parcels. The decentralized wastewater treatment units spread a Biological Oxygen Demand (BOD) reduction of the wastewater throughout the system and effluent is delivered efficiently through a pressure sewage system. Non-potable and potable water supplies are generated and delivered to individually separable water distribution zones throughout the municipality. The system also provides an auxiliary high-pressure, high-flow non-potable water supply to compensate during depressurization events and bolster the water distribution zones in the event of a wildfire emergency event.
