Abstract:
1. A septic tank system comprising: a tank adapted to receive sewerage, said tank having a tank outlet positioned to discharge liquid effluent from said tank; a downstream fluid system in fluid communication with said tank outlet and conveying effluent discharged from said tank to at least one discharge location where the effluent is discharged from said septic tank system; a treatment chamber operably disposed in said downstream fluid system between said tank outlet and said at least one discharge location, said treatment chamber having an interior surface defining a chamber volume wherein effluent discharged from said tank into said downstream fluid system flows through said chamber volume, said chamber volume being an elongate volume defining a chamber axis, said treatment chamber being positioned wherein said chamber axis defines an angle with a horizontal plane of less than approximately 5 degrees; and an ultraviolet light emitting device removably insertable into said chamber volume and non-sealingly engageable with said interior surface, said ultraviolet light emitting device being an elongate device defining a second axis, and wherein said device comprises first and second pluralities of spacing elements, said first plurality of spacing elements being disposed at circumferentially spaced locations proximate a first end of said device and said second plurality of spacing elements being disposed at circumferentially spaced locations proximate a second end of said device, said spacing elements being engageable with said interior surface to thereby non-attachedly position said device in said chamber volume with a substantial portion of said device being spaced from said interior surface and said second axis being disposed below and substantially parallel with said chamber axis whereby said device may be substantially completely surrounded by the effluent when said chamber volume is only partially filled with effluent.
