Abstract: A chemical dispensing assembly having a base member, a flow chamber, a chemical chamber and a dispensing control conduit, wherein water or other liquid flows through the base member, into the flow chamber, through the dispensing control conduit and out the base member, wherein a small amount of saturated solution retained within the chemical chamber is drawn into the water flow, the chemical chamber being connected below the flow chamber and the volume of the chemical chamber being greater than the volume of the flow chamber. Preferably, the flow chamber is connected to the base member with a bayonet-type connection mechanism, and keys and key slots are provided such that only dedicated flow chambers can be connected to the base member.

Abstract: An adjustable device for delivering chemical solutions into a liquid flow, where a saturated chemical solution is created by dissolving solid chemical contained within a chemical dispensing chamber, the device retained within a housing connected into a fluid flow line such that liquid for treatment flows therethrough. The device allows for adjustment or control of the amount of liquid flow into the dispensing chamber, the amount of saturated chemical solution drawn from the dispensing chamber by the main liquid flow, and the amount of main liquid flow through the device.

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.

Abstract: A device for delivering chemical solutions into a liquid flow within a chemical dispensing unit, where said chemical solution is created by dissolving solid chemical contained within a chemical cartridge, the unit having a base member and housing connected into a fluid flow line such that liquid flows into the base member, into the housing and back out through the base member or through the top of the housing, the chemical dispenser device having an upper conduit member, an apertured midsection, a chemical containing lower cartridge and a coaxial tube extending through the cartridge, the cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its top, such that a saturated chemical solution is formed in said cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing into the apertured midsection and out through either the upper conduit or through the coaxial conduit.

Abstract: A device for delivering chemical solutions into a liquid flow, where said chemical solution is created by dissolving solid chemical contained within a chemical cartridge, the device having a uni-directional flow housing connected into a fluid flow line, and further having a chemical dispenser having an upper conduit member, an apertured midsection and a chemical containing lower cartridge, the cartridge having an intake aperture located on the upper portion of its side wall and a dispensing aperture on its top, such that a saturated chemical solution is formed in said cartridge and passes into the liquid flow through the dispensing aperture due to the pressure differential of the liquid flowing into the apertured midsection and through the upper conduit out of the device.
