Liquid waste treatment apparatus

Abstract

A fluid conduit with layered and partial covering material thereon is disclosed. The fluid conduit may be used for processing and treatment of fluids which must be treated to remove materials so that the resultant treated fluid may be reused and/or returned to the earth and particularly to the water table. The fluid conduit may be of many forms and types and may have attached thereto and configured thereon covering material in partial form and a selected number of layers. The fluid conduit may be a septic pipe of smooth wall, of corrugated form, and/or of any form of cross-sectional configuration including circular, elliptical, rectangular, triangular, or any other geometric shape. The fluid conduit may be used in combination with conduit in a drainage field or leaching system usually associated with a septic tank or septic system.

What is claimed is: 
     
         1 . A waste water treatment system comprising:
 a conduit constructed and arranged to be in fluid communication with a septic system, the conduit having a circumference and a side wall with perforations there through;   a plastic grid mesh;   a first fabric layer outside the plastic grid mesh;   a second fabric layer positioned outside the first fabric layer and covering completely the circumference of the conduit; and   a coarse layer positioned between the first fabric layer and the second fabric layer, the coarse layer covering less than one half the circumference of the conduit.   
     
     
         2 . The waste water treatment system of  claim 1 , wherein the first fabric layer and the second fabric layer are of varying deniers. 
     
     
         3 . The waste water treatment system of  claim 1 , wherein the conduit is corrugated plastic pipe. 
     
     
         4 . The waste water treatment system of  claim 1 , further comprising a biolayer. 
     
     
         5 . The waste water treatment system of  claim 1 , further comprising a second coarse layer, the second coarse layer covering a greater area than the first coarse layer. 
     
     
         6 . The waste water treatment system of  claim 1 , wherein the plastic grid mesh is in contact with the conduit. 
     
     
         7 . The waste water treatment system of  claim 1 , wherein the first fabric layer covers less than one half the circumference of the conduit. 
     
     
         8 . The waste water treatment system of  claim 1 , wherein the first coarse layer comprises a layer of random fibers. 
     
     
         9 . The waste water treatment system of  claim 8 , wherein the layer of random fibers is an unstructured assemblage of fibers. 
     
     
         10 . The waste water treatment system of  claim 1 , wherein at least one of the fabric layers is a geotextile fabric. 
     
     
         11 . A waste water treatment system comprising:
 a conduit constructed and arranged to be in fluid communication with a septic system, the conduit having a circumference and a side wall with perforations there through;   a plastic grid mesh surrounding the conduit;   a multi-layered fabric positioned outside the plastic grid mesh, the multi-layered fabric comprising at least a first fabric layer and a second fabric layer;   the second fabric layer positioned outside the first fabric layer and covering completely the circumference of the conduit; and   a coarse layer positioned between the first fabric layer and the second fabric layer, the coarse layer covering a partial circumference of the conduit.   
     
     
         12 . The waste water treatment system of  claim 11 , further comprising a third fabric layer and a second coarse layer, the third fabric layer positioned between the coarse layer and the second coarse layer. 
     
     
         13 . The waste water treatment system of  claim 12 , wherein the third fabric layer covers a greater portion of the conduit than does the first fabric layer. 
     
     
         14 . A waste water treatment system comprising:
 a conduit having a circumference and a side wall with perforations there through;   a plastic mesh surrounding the conduit;   a first fabric layer outside the plastic mesh constructed and arranged to form a series of alternating peaks and troughs;   a second fabric layer positioned outside the first fabric layer and covering completely the circumference of the conduit; and   a coarse layer positioned between the first fabric layer and the second fabric layer, the coarse layer covering a partial circumference of the conduit.   
     
     
         15 . The waste water treatment system of  claim 14 , wherein each peak and trough in the series of alternating peaks and troughs is U-shaped. 
     
     
         16 . The waste water treatment system of  claim 14 , further comprising a spacer within each of the peaks and troughs to retain the shape of the series of peaks and troughs. 
     
     
         17 . The waste water treatment system of  claim 14 , further comprising a biomat layer on the second fabric layer. 
     
     
         18 . The waste water treatment system of  claim 14 , wherein the second fabric layer is positioned between a spacer and the first fabric layer. 
     
     
         19 . A method of treating effluent comprising:
 passing the effluent along an interior of a conduit including apertures therethrough;   restricting a flow of the effluent out of the apertures with a dense fabric layer;   causing at least a portion of the effluent to overflow upper edges of the dense fabric layer; and   flowing the effluent through an outer layer of fabric.   
     
     
         20 . The method of treating effluent of  claim 19 , further comprising passing the effluent through coarse fibers prior to flowing the fluid through the outer layer of fabric.
