ABSTRACT:
System for automatic control of chlorine content and pH in swimming pools. This system includes an electrolytic cell for generation of chlorine and caustic soda as needed, and an acid supply system for adding hydrochloric acid to the pool as required. Generation of chlorine and addition of acid are controlled automatically in response to sensed oxidation-reduction potential (ORP) and pH of the swimming pool water. The sensors for this purpose may be placed in a conventional pool recirculation line, and chlorine, caustic soda (which is co-produced with chlorine) and hydrochloric acid may be added to the pool via the recirculation line.
The electrolytic cell has a porous separator dividing the cell into anolyte and catholyte compartments. The latter is operated at a slightly higher pressure than the former. Chlorine generated in the cell is separated from spent brine, which is recirculated back to a brine tank where it is resaturated. The system may include a timer.
