US 6,440,304 B2 · In-line filtration system for treatment of septic tank effluent

Abstract

An apparatus and method for treatment of waste water effluent includes a main conduit connected to a source of waste water, and a removable filter positioned within the main conduit, the filter having a light weight particulate material for filtration of the effluent. A drain field for filtration treatment of waste water effluent includes a source of waste water effluent, a main conduit in fluid connection with the source of waste water, and at least one in-line filter positioned within the main conduit, the filter having a light weight particulate material. The drain field may include at least one extension conduit connected in fluid communication with the main conduit and extending substantially upwardly therefrom, the extension conduit having a removable cap and a sensor to thereby generate a signal when water in the extension conduit reaches a predetermined level.

Dependent claims

A drain field for filtration treatment of waste water, said drain field comprising:

a source of waste water;
a U-shaped conduit having an interior passage in fluid connection with said source of waste water and downstream therefrom for the waste water to flow therethrough;
and
a filter comprising a water permeable sleeve defining a periphery of said filter and containing light weight particulate material, said filter positioned within the interior passage of said U-shaped conduit having the periphery extending to contact side walls of the interior passage so that said filter fully occupies a length of the interior passage of said conduit to thereby substantially prevent waste water from bypassing said filter.
