Attached growth bacteria grow on a plurality or random directional brushes (116) in an effluent tank, e.g., septic tank (14). ## Claims ### Claim 1 A wastewater treatment apparatus for the remediation of a wastewater treatment system, such wastewater treatment system being comprised of at least one septic tank, the septic tank having at least a lower sludge layer and an upper effluent layer, the septic tank further having an outlet to a distribution system and a leaching system, wherein effluent drains from the tank outlet through the distribution system and to the leaching system; the wastewater treatment apparatus comprising: at least one positive pressure generating pump having an output; a plurality of brushes, the brushes being situated within the liquid effluent in a septic tank; a tube having a first end and a second end, the first end being attachable to the pump output; an air stone attachable to the second tube end, said air stone being used to introduce air into the effluent and encourage aerobic bacteria to proliferate; a plurality of brushes providing a platform for attached growth within the effluent layer. ### Claim 2 (depends on 1) The apparatus of claim 1 further comprising the use of one or more ozone generating devices instead of or in combination with one or more air pumps. ### Claim 3 (depends on 2) The apparatus of claim 2 wherein the plurality of pumps, tubes and air stones are distributed at different locations throughout the system. ### Claim 4 (depends on 1) The apparatus of claim 1 wherein the air stone comprises a low pressure drop sintered air stone having a relatively large surface area. ### Claim 5 (depends on 1) The apparatus of claim 1 wherein the at least one pump is electrically actuated and includes internal electrical connections that are packaged within a weatherproof container. ### Claim 6 (depends on 1) The apparatus of claim 1 wherein the tubing is made from a vinyl material. ### Claim 7 (depends on 1) The apparatus of claim 1 further comprising means for introducing one or more from a group consisting of anaerobic bacteria, aerobic bacteria, facultative bacteria, enzymes and vitamins to the system. ### Claim 8 (depends on 1) The apparatus of claim 1 wherein the apparatus is utilized with at least one holding tank. ### Claim 9 (depends on 1) The apparatus of claim 1 wherein the apparatus is utilized with at least one mobile and/or portable holding tank. ### Claim 10 (depends on 1) The apparatus of claim 1 wherein the brushes are suspended within the septic tank in the effluent above the air stone. ### Claim 11 (depends on 1) The apparatus of claim 1 wherein the air stone is suspended within the septic tank in the effluent below the brushes, but above the sludge layer. ### Claim 12 A method for the remediation of a wastewater treatment system, such system being comprised of at least one septic tank having an outlet, or one septic tank with porous walls and or bottom without an outlet pipe, a distribution system and a leaching system, wherein liquid effluent drains from the tank outlet through the distribution system and to the leaching system, comprising the steps of: providing at least one positive pressure air or ozone generating pump having an output; providing a tube having a first end and a second end, the first end being attachable to the pump output; providing an air stone that is attachable to the second tube end; introducing the air stone into a portion of the system containing liquid effluent; suspending one or more brushes in the liquid effluent to create a surface area fro attached growth of aerobic bacteria; and delivering air or ozone through the tube into the effluent via the air stone to encourage aerobic bacteria to proliferate therewithin. ### Claim 13 (depends on 12) The method of claim 12 wherein the plurality of pumps, tubes and air stones providing steps include distributing the plurality of such pumps, tubes and air stones at different locations throughout the system. ### Claim 14 (depends on 12) The method of claim 12 wherein the air stone providing step includes providing a low pressure drop sintered air stone having a relatively large surface area. ### Claim 15 (depends on 12) The method of claim 12 wherein the pump providing step includes providing a pump that is electrically actuated and includes internal electrical connections that are packaged within a weatherproof container. ### Claim 16 (depends on 12) The method of claim 12 further comprising the step of introducing one or more from a group consisting of anaerobic bacteria, aerobic bacteria, facultative bacteria, enzymes and vitamins to the system. ### Claim 17 (depends on 12) The method of claim 12 wherein the method is adapted for use with at least one holding tank. ### Claim 18 (depends on 12) The method of claim 12 wherein the method is adapted for use with at least one mobile and/or portable holding tank. ### Claim 19 A method for remediating a wastewater treatment system, such system being comprised of at least one septic tank having an inlet and an outlet or one septic tank with porous walls and or bottom without an outlet pipe, and at least one absorption field wherein effluent drains from the tank outlet, wherein an accumulation of bio-mat has reduced the flow of effluent through the absorption field, comprising the steps of: introducing a combination of ozone and air to the bio-mat; introducing one or more brushes to provide for attached growth of aerobic bacteria in the liquid effluent; introducing live aerobic bacteria to the bio-mat; monitoring the level of effluent in the absorption field; and stopping the introduction of ozone and air to the effluent when the bio-mat is sufficiently reduced or made permeable. ### Claim 20 (depends on 19) The method of the claim 19 further comprising the step of introducing live anaerobic bacteria to the system after stopping the introduction of ozone and air to the system.
