Abstract: Systems, apparatuses, and methods of treating wastewater are provided. In some aspects, a container may be provided and may include a first member, a second member spaced apart from the first member, and media supported by and extending between the first and second members. An organism may be introduced into the container and wastewater may be introduced into the container for treatment. The media may be loop cord media. In other aspects, two containers may be provided and wastewater may be initially introduced into a first container for treatment, removed from the first container, and subsequently introduced into the second container for further treatment. A first species of organism may be present in the first container and a second species of organism may be present in the second container. Methods of using these containers are also provided.

Abstract: Cultivators and methods of cultivating microorganisms are provided. In some examples, a cultivator may include a retaining wall defining a cavity for retaining liquid and may also include a horizontally orientated frame at least partially positioned within the cavity and having media for supporting microorganisms. In other examples, the horizontal frame may be partially submerged in the liquid retained in the cavity and rotatable to selectively submerge and unsubmerge portions of the frame and media.
