Patent number: 11897787Abstract: A wastewater management system includes a series of water treatment modules to treat wastewater and produce reusable and/or potable water and other beneficial byproducts of the wastewater treatment process. A pretreatment module, a filtration module, an evaporator module, an odor control module, a UV-light module, an autoclave module, a sonolysis module, an ozone module and a chlorination module are combined in multiple combinations along with holding tanks, condensers, flash tanks and other components to address water purification and reclamation needs based upon specific wastewater conditions. The system captures condensate from AC systems and rainwater from rainwater gutter systems processes the water to produce reusable and/or potable water with or without re-mineralization. Any CO2 produced by the water treatment system is captured and processed using naturally-occurring flora.Type: GrantFiled: July 18, 2022Date of Patent: February 13, 2024Assignee: ZERO DISCHARGE, LLCInventors: David D. Calhoun, Mark D. Lorusso, R. Edward Rose, Jr., Ernest M. Hawkesworth

Patent number: 11390545Abstract: A wastewater management system includes a series of holding tanks in combination with a membrane bioreactor treatment subsystem connected to one or more autoclaves and/or sonolysis units and thermal evaporators to treat liquid discharge from the system. A condenser connected to the thermal evaporator(s) condenses water vapor created by the thermal evaporator(s) into its liquid state for delivery to, and assimilation by, plants in a dedicated greenhouse or hydroponic system or for reuse in a building. CO2 and water vapor produced by combustion of a thermal evaporator fuel source is sent through the condenser to add to the liquid water recovery. The CO2 is flowed into the greenhouse(s) for carbon fixation by plants. A CO2 monitoring system ensures the concentration of CO2 in the greenhouse is maintained at an acceptable level for humans. Ozonation, UV and/or chloride treatments may be used as optional water purification treatments in the system.Type: GrantFiled: April 29, 2020Date of Patent: July 19, 2022Assignee: ZERO DISCHARGE, LLCInventors: David D.
