SACZ Engineering was approached in order to determine a method for treating a pool water system without imparting spiked chlorine concentrations, and their associated health risks, into the system. A saltwater chlorinator system was designed in order to overcome this problem by providing constant chlorine levels in the pool system. This design consists of a device which conducts electrolysis on salt water in order to produce chlorine gas which is immediately dissolved into the pool water. Research was conducted into the various pre-existing pool treatment methods and it was found that this method is the most desirable both financially and from an operational feasibility point of view.
