  • Patent number: 9487421
    Abstract: A scalable, modular water filtration and re-capture system is disclosed, such as for use as a high performance bioswale, or other purposes. The system includes a filter container with a removable cartridge that contains a filter media soil and planted vegetation, which may be for example one or more hyperaccumulators. The filter container is stacked together with a cistern container and in fluid communication therebetween to form a stacked container pair as a water filter and capture module. This allows for efficient servicing and removability of the filter cartridge, such as in bioswale, below ground, or above ground configurations. Water inflows and outflows may be circulated for varieties of reclamation uses, or treated water may simply be stored or conveyed into the ground. Multiple such modules may be secured together in custom scalable configurations to meet various needs and intended uses for water volumes, available space or terrain, or specific water treatment needs.
