ABSTRACT:
A device for delivering chemical solutions into a liquid flow, where the chemical solution is created by dissolving solid chemical contained within a chemical dispenser cartridge, the dispenser cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its removable cap member, such that a saturated chemical solution is formed in the cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing through a tubular filter, the dispenser cartridge being mounted within the tubular filter.
