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 desired 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 desired level during the life of the timing cycle then an signal is output to indicate that the bromine cartridge is depleted.
