ABSTRACT:
A portable wastewater treatment system comprising a wastewater holding tank having an interior adapted to hold wastewater, and a generator positioned to provide ozone, oxygen, or a combination of the two to the interior of the holding tank. In one embodiment, the holding tank comprises a gray-water tank, and the system further comprises a non-potable water tank having an interior. In this embodiment, the system further includes a second generator positioned to provide ozone, oxygen, or a combination of the two to the interior of the non-potable water tank and a conduit coupling the gray-water tank to the non-potable water tank. The system can further include a black-water tank having an interior, a third generator positioned to provide ozone, oxygen, or a combination of the two to the interior of the black-water tank, and a conduit coupling the black-water tank to the non-potable water tank. The system can further include a toilet having an inlet and an outlet, a first conduit coupling the non-potable water tank to the inlet of the toilet, and a second conduit coupling the outlet to the black-water tank. The system can also include a potable water tank, a point of water usage coupled to the potable water tank, and a fourth generator positioned to provide ozone, oxygen, or a combination of the two to the potable water tank.
