The present invention is directed to a method for filtering fluid, preferably effluent fluid in a septic system, by providing a staged, filtering array in an effluent flow path, the stages positioned in an orientation designed to maximize filtering capability in conjunction with predetermined apertures.

Multi-level filter device

A gas baffle for a waste water treatment plant filter housing that includes a first and second deflecting plate. The gas baffle has at least one flow-through opening defined by the first and second deflecting plates. The combination of the first and second deflecting plates deflects rising gas bubbles and any solid particulates so that the bubbles and particulates do not enter the filter housing. The gas baffle may include exterior apertures to dissipate the rising gas bubbles that travel on the bottom surface of each deflecting plate. The gas baffle may be integrally formed with the filter housing or created separately and subsequently connected.

Methods, systems and apparatuses are disclosed for improving the treatment of wastewater in a dispersal drainage trench by facilitating the direct aeration of wastewater passing through a drainage unit.

Micro diffusion of oxygen for treatment and dispersal of wastewater in a drain field

A riser system for use at the access opening of a wastewater treatment tank includes an adaptor ring affixed to the top of the tank, and a mating riser. The adaptor ring and riser have ends with mating circumferential L-shape sections. There are horizontally projecting tabs spaced apart around the upper end of the adaptor. The tabs engage a corresponding number of L-shape slots which are spaced apart around the circumference of the bottom end of the riser. When ring and riser are mated, rotation of the riser relative to the adaptor causes each tab to move circumferentially to a recess in the slot, which locks the tab in position. Micro-ridges on horizontal mating surfaces of the L-shape sections help form a seal between the two parts.

Risers for use with access openings in wastewater treatment tanks

A filter unit for use in a casing disposed in a septic tank comprising a plurality of stacked filter plates. The individual filter plate is preferably substantially 'D' shaped in circumference and has a substantially cone-shaped floor, tapering upward. The filter plates are preferably stacked in a superposed, spaced-apart manner with a particular diameter in relationship to the inner diameter of the case. The filter plates are preferably inserted into the filter case to define a seal horizontally around the bottom opening in the case, thereby allowing wastewater to enter into the filter plates to begin the filtering process. Solids preferably flow upward into the filter plates, where they are separated by size with a predetermined gap in the stacked filter plates.
