Abstract:

The apparatus for UV wastewater purification in septic tank systems has an ozone free ultraviolet lamp disposed in PVC piping buried in the ground and located between the septic tank and the drainfield. The PVC piping includes a water inlet and an outlet connected by a U-shaped section of piping. The UV lamp is housed in a quartz tube, or in an alternative embodiment, in a Teflon tube, and placed in a cylindrical insert having a plurality of ports defined in the walls of the cylinder. The insert is placed in a vertically oriented leg of the U-shaped piping at the water outlet, the wastewater flowing through the insert parallel to the ultraviolet lamp. Access to the UV lamp for maintenance is provided by a vertically oriented riser pipe buried in the ground and having a length corresponding to the desired depth of the apparatus, the riser housing the electrical wiring and having a cap at ground level. The method for UV wastewater purification in septic tank systems includes the steps of selecting an ozone free UV lamp, disposing the lamp in a cylindrical insert having a plurality of ports, and placing the insert in PVC piping buried in the ground between the septic tank and the drainfield.
