Abstract
(EN)
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.

La présente invention concerne un système de gestion d'eaux usées comprenant une série de réservoirs de stockage en combinaison avec un sous-système de traitement de bioréacteur à membrane connecté à une ou plusieurs autoclaves et/ou unités de sonolyse et évaporateurs thermiques pour traiter une décharge de liquide provenant du système. Un condenseur connecté aux évaporateurs thermiques condense la vapeur d'eau créée par les évaporateurs thermiques dans son état liquide pour la distribution à, et l'assimilation par, des plantes dans une serre ou un système hydroponique dédié ou pour une réutilisation dans un bâtiment. Le CO2 et la vapeur d'eau produits par la combustion d'une source de combustible d'évaporateur thermique sont envoyés à travers le condenseur pour ajouter à la récupération d'eau liquide. Le CO2 s'écoule dans la ou les serres pour la fixation du carbone par les plantes. Un système de surveillance de CO2 garantit que la concentration de CO2 dans la serre est maintenue à un niveau acceptable pour les êtres humains. Des traitements d'ozonation, d'UV et/ou de chlorure peuvent être utilisés en tant que traitements facultatifs de purification d'eau dans le système.
