SEPTIC TANK FILTERING SYSTEM

摘要

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.
