Abstract: A filtering system for filtering effluent in a septic tank including an outer secondary filter secured within a pipe fitting, wherein the outer secondary filter includes a central opening passing therethrough; an inner primary filter, wherein the inner primary filter is slidingly engaged within the central opening in the outer secondary filter; and a filtering connection element, secured between the outer secondary filter and an inner surface of the pipe fitting, wherein the filtering connection element filters effluent passing upward through the filter pipe fitting and wherein upon removal of the inner primary filter, the outer secondary filter filters the effluent entering the pipe fitting before discharge. Either or both of the outer secondary filter or the inner primary filter may be formed with a biocide to retard the growth of biological material on their surfaces.

Abstract: A liquid distribution system for distributing effluent from a source of waste water. This liquid distribution system is contained within a distribution box and includes liquid inlet piping, a ramp system, and a low capacity liquid flow splitting system, including slots and capillary grooves. A high capacity flow splitting system may also be included. In addition, an adjustment system is incorporated into the liquid distribution system for maintaining the level of the liquid distribution system in the ground.

Abstract: Disclosed is a waste water treatment system which includes a water impervious container, a uniform effluent distribution system for distributing effluent in a uniform manner throughout the container, material fill which is placed within the container, an effluent introduction system for introducing the effluent into the material filled container and an outflow mechanism which permits treated effluent to flow out of the waste water treatment system. Also disclosed is a waste water treatment cell system containing a plurality of individual cells for the treatment of the effluent and a system for dumping substantially all of the filtered effluent from the waste water distribution system. Also disclosed is a process for the treatment of waste water using the waste water treatment system.

Abstract: A filtering system for filtering effluent in a septic system comprising a filter housing with sides, a top and an open bottom, a filter element holder secured within the filter housing, wherein the filter element holder contains a top and a side portion, a discharge opening in the filter housing located generally above the filter element holder for discharging filtered effluent from the filter housing, a plurality of filter elements, each secured to the filter element holder, each with a top, bottom and side, wherein the bottom of each filter element is closed to prevent flow of the effluent through the bottom of the filter element, wherein each filter element contains filtering slots for filtering solids contained in the effluent and a separation element for separating one filter element from other filter elements, which element does not significantly impede the flow of effluent through the filtering system.
