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 wastewater treatment apparatus for a wastewater treatment system that includes a septic tank with a lower sludge layer, an upper effluent layer, and a tank floor. The wastewater treatment apparatus includes a positive pressure pump that is configured to pump a fluid, and a tube that has an outlet that is spaced from the tank floor. The tube is in fluid communication with the positive pressure pump.

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 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.

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.

Abstract: A rotary indexing switch includes a base having a series of radially spaced stationary contact areas, and a rotary contact member having a rotary contact area. The stationary contact areas are defined by contact members engaged within passages in an insulating ring in a configuration dictated by specifications of the switch. The switch has a number of unique features, including mating engagement structure that drivingly engages actuator shafts of stacked switch assemblies; a spring for biasing the rotary contact member toward the stationary contact areas; a combination lift and detent arrangement for lifting the rotary contact areas away from the stationary contact areas and maintaining the rotary contact member in a contact position when the rotary contact areas are engaged with the stationary contact areas; a center contact selectively engageable with the base utilizing a cooperating engagement arrangement; and an integral enclosure wall which forms a dust shield.
