ABSTRACT:
The chlorinator for a swimming pool with a recirculation system includes a container to hold a column of chlorine concentrate solution, and a pool water supply conduit with a flow regulator connected to a return conduit of the recirculation system. Some of the pool water is caused to slowly flow into the container forming a gradually increasing column of pool water above the chlorine concentrate solution inside the container. A layer of separating material, having a specific gravity between that of pool water and that of the chlorine concentrate solution, rests on the bottom of the pool water in the container and floats on top of the column of the chlorine concentrate solution, and effectively prevents mixing of these two liquids. The gradually increasing column of pool water in the container then gradually forces the chlorine concentrate solution out of the container through another supply conduit to a height between the top and bottom of the container. A feeder member, connected to the return conduit and positioned below the output of the chlorine concentrate supply conduit, receives the chlorine concentrate solution from this supply conduit to add it to the pool water returning to the swimming pool.
