Abstract
A new and improved swimming pool chlorinator which facilitates the provision of a higher strength hypochlorite solution over a wide concentration range than can be obtained from prior swimming pool chlorinators. The new and improved chlorinator utilizes a membrane type cell having opposed catholyte and anolyte chambers including a cathode and an anode member, respectively, disposed in a close spaced relationship to each other and separated by a substantially hydraulically impermable cation exchange membrane. The products of electrolysis in the catholyte and anolyte chambers are combined exteriorally of the cell to obtain sodium hypochlorite which may then be conveyed to the swimming pool water. Means are provided to selectively vary the electrical current in the cell to control the amount of sodium hydrochlorite ultimately produced.
