Abstract: A wastewater treatment apparatus for remediation of a wastewater treatment system has a septic tank with a lower sludge layer and an upper liquid effluent layer. The apparatus is comprised of a brush that includes a brush arm having a first end, a second end, and bristles disposed on the brush arm between the first end and the second end. The brush is configured to be positioned within the liquid effluent layer in the septic tank in a vertical orientation such that the second end is disposed below the first end.

Abstract: A self-uprighting aeration device that minimizes turbulence and disruption of any sediment layer in a tank. The device includes a float positioned about a first position on a longitudinal axis of the aeration device, a ballast positioned about a second position on the longitudinal axis, and a diffuser. The float and the ballast are configured to orient the aeration device in a liquid with the longitudinal axis substantially aligned with a gravitational vector to dispose the diffuser above the sediment layer. The aeration device can be configured to rest on a support surface in the tank or float above such a support surface. Methods for aerating liquid in tanks with the aeration device are also provided.

Abstract: A wastewater treatment system comprising a first chamber adapted to receive wastewater and arranged to perform a first treatment process (e.g., aerobic and/or anaerobic processes), a second chamber positioned to receiving wastewater from the first chamber and including an ozone contactor assembly that infuses ozone into the second chamber, and a storage tank positioned to receive treated water from the second chamber. The ozone contactor assembly comprises a first conduit having an intake, a discharge, a downwardly-angled portion, and an upwardly-angled portion (e.g., U-shaped). An ozone generator is positioned to provide ozone to a lower portion of the first conduit (preferably near the bottom of both the downwardly- angled portion and the upwardly-angled portion). The ozone contactor assembly can include additional conduits structured similar to the first conduit and feeding into each other, and each including an ozone generator.

Abstract: A method and apparatus for remediating a failing wastewater treatment system comprising a positive air, oxygen, ozone, or combination thereof, generating pressure pump (40) directing the air, oxygen, ozone or combination through a tube (50) to an air stone (60) suspended in the effluent. Attached growth bacteria grow on a plurality or random directional brushes (116) in an effluent tank, e.g., septic tank (14).

Abstract: A method and apparatus for remediating a failing wastewater treatment system comprising (a) a positive oxygen and ozone-generating, or ozone-generating only, pressure pump having an output, (b) a tube having a first end and a second end, the first end being attachable to the pump output, and (c) an air stone attachable to the second tube end. The pump is used to deliver oxygen and ozone, or ozone only, through the tube to the air stone. As much tube as is required is used to allow the air stone to be introduced into almost any portion of the wastewater treatment system so as to introduce air into the effluent and allow aerobic bacteria to proliferate. The apparatus of the present invention could also include a plurality of such pumps, tubes and air stones, and in many combinations.
