Patent number: 11623876Abstract: A scalable phytoremediation system that uses rock medium supporting a Salicaceae (poplar or willow) tree rhizosphere in a basin with controllable volume and water depth that results in tertiary treatment requirements for organic BOD, pathogens, ammonia-nitrogen, nitrate-nitrogen and phosphorous pollutants and PFAS. COC removal is achieved by pollutant sorption, plant uptake and increased microbial mineralization activity. Phyto basin achieves faster pollutant mineralization to achieve regulated water quality standards. The Basin reactor system uses photosynthesis and rhizosphere dynamics to create a predictable reactor into carbon-rich microbial biomass to remove waste water pollutants (COC). The Basin uses <10% of the energy required for alternative tertiary treatment system. The Basin COC treatment functions year-round including through the trees dormant season.Type: GrantFiled: February 25, 2021Date of Patent: April 11, 2023Inventor: Louis A. Licht
