An improved chlorination system for pools, spas, potable water supplies,
and the like, provides a vertically oriented electrolytic cell connected
between a pump and a lightly salinated pool. The cell preferably contains
a metallic electrode, such as copper, and a precious metal coated titanium
electrode, and has means for passing an electric current through the cell.
The present invention further provides a novel electrode stack design,
conducive for forming an efficient chlorinator comprising a plurality of
interconnecting electrode stacks of separate electrical cells.
