The chlorinator includes a cylinder portion that has a plurality of openings through which the waste water flows through to make contact with at least one chlorine table. The cylinder portion of the chlorinator also includes an inner surface that is non-reactive with the chlorine tablets and that enables the chlorine tablets to slide thereon. The waste stream comprises septic wastewater, which originates from toilet systems, and gray wastewater, which originates from somewhere other than toilet systems, such as sinks. The chlorinator selectively treats the septic wastewater by contacting it with the chlorine tablets but does not contact the gray wastewater with the chlorine tablets. In the preferred embodiment, a passageway provides fluid communication between the upstream side of the waste stream and the base portion of the chlorinator without directing any of the gray wastewater through the cylinder portion. An alarm mechanism detects the low level of the chlorine tablets, preferably with a push-button sensor. ## Claims ### Claim 1 A chlorinator for aerobic waste treatment systems or water treatment systems, comprising: a cylinder portion adapted to hold a plurality of chlorine tablets therein; said cylinder portion including a plurality of openings providing fluid communication between a waste stream and said plurality of chlorine tablets so that said waste stream comes in contact with all surfaces of at least one of said plurality of chlorine tablets; said cylinder portion including a first end, a second end, and an outer surface; said plurality of openings comprising a plurality of passages and a plurality of holes; said cylinder portion second end including said plurality of passages allowing fluid communication therethrough; said cylinder portion outer surface including said plurality of holes proximate said cylinder portion second end allowing fluid communication therethrough; a joint portion functionally attached to said cylinder portion and to said waste stream; said joint portion including a central interior region; said plurality of holes located within said central interior region when said cylinder portion is functionally attached to said joint portion; a proximate base portion; said joint portion including four inlets; each of said four inlets leading to said central interior region; said four inlets comprising two sets of opposing inlets; said cylinder portion and said base portion functionally attached to two of said opposing inlets; and said waste stream functionally attached to the remaining two of said opposing inlets. ### Claim 2 (depends on 1) A chlorinator as in claim 1, further comprising a passageway providing fluid communication between an upstream side of said waste stream and said base portion without directing a gray water of said waste stream through said cylinder portion. ### Claim 3 (depends on 2) A chlorinator as in claim 2, wherein: said cylinder portion having an outer cross-sectional diameter; said joint portion including an inlet; said inlet having an inner cross-sectional diameter; said cylinder portion outer cross-sectional diameter at said cylinder portion second end being smaller than said inlet inner cross-sectional diameter thereby defining an annular space therebetween; and said passageway comprising said annular space. ### Claim 4 (depends on 1) A chlorinator as in claim 1, further comprising a means for sensing the presence of said chlorine tablets within said cylinder portion. ### Claim 5 (depends on 4) A chlorinator as in claim 4, wherein: said means for sensing comprising a push button sensor; said push button sensor attached to said proximate base portion; said push button sensor supporting said chlorine tablets; said cylinder portion at said cylinder portion second end including a cylinder portion second end hole; said push button sensor protruding into said cylinder portion second end through said cylinder portion second end hole; and said sensor sensing when a weight of said chlorine tablets has dropped below a pre-determined value. ### Claim 6 (depends on 5) A chlorinator as in claim 5, wherein: said means for sensing activates a low chlorine alarm. ### Claim 7 (depends on 5) A chlorinator as in claim 5, wherein: said means for sensing deactivating a pump in a pump tank of said aerobic waste treatment system.
