EFFLUENT ENERGY RECOVERY SYSTEM

摘要

A septic system thermal recovery mechanism (12) includes a septic tank (56). The tank (56) has a top (58), a bottom (60), and at least one upstanding side wall (62) joining the top (58) to the bottom (60). A septic inlet (66) is adapted and constructed to conduct septic waste material into the interior (64) of the tank, and a septic outlet (68) is adapted and constructed to conduct septic waste material out of the interior (64) of the tank. A thermal exchange fluid conduit (70) is embedded in the at least one wall of the tank. The side wall (62) can be provided as a cast concrete wall, with the thermal exchange fluid conduit (70) being PEX tubing embedded in side wall (62) in a spiral configuration at the time the side wall is cast. the thermal recovery mechanism (12) can also include a second thermal exchange fluid conduit (76) embedded in the top (58) of the tank.
