ABSTRACT:
A process of and apparatus for determining when the effective bromine contained in a polybromide impregnated resin cartridge used in a water disinfection system is depleted. The bromine content of the supply water is measured. When the bromine content falls below a pre-determined level, a comparative circuit is actuated to initiate flow of the supply water through a bromine cartridge assembly. At the same time, a timing cycle is initiated. The bromine content is continuously monitored and if it does not rise above the pre-determined level during the life of the timing cycle then an signal is output to indicate that the bromine cartridge is depleted.
