A chlorine generating apparatus is disclosed herein by which chlorine gas or sodium hyperchlorite is generated in small quantities from a brine solution economically enough to be practical for use in the backyard swimming pool. The apparatus includes a free standing unit and cell utilizing only salt as its raw material to generate the chlorine required. The chlorine generating cell incorporates a chemical pump for forcibly urging the resulting product to the pool without the use of mechanical pumps or membranes. A device is included whereby hardness minerals are prevented from being deposited within the cell. New methods of reducing maintenance and increasing reliability are also disclosed.

A water sterilization and alkalinity control system according to claim 7 wherein: a second storage contaner is provided into which the portion of the sodium hydroxide not used to generate sodium hypochlorite is allowed to accumulate, said container having an overflow to waste; two venturi fittings, the pressure side of each connected through two solenoid valves to the pressure side of the filter in the circulation system of the water to be treated, the output of each venturi fitting connected through a check valve to the lower pressure return line of said circulation system; the suction input of the first venturi connected to draw sodium hypochlorite from the first storage container when the solenoid valve on its pressure side is caused to open, the second venturi having its suction input connected to a line so arranged to draw sodium hydroxide from the second storage container when the solenoid valve connected to its pressure side is caused to open; a chlorine and alkalinity sensing means connected to sense the chlorine and alkalinity levels of the water to be treated as it flows through its filter system, said sensing means connected to a control unit whereby the appropriate solenoid valve is caused to open to adjust the water\s chlorine and alkalinity to predetermined levels.
