Abstract
A method of maintaining a safe free chlorine level in a body of water for recreational use where the free chlorine level at a harmful level comprises determining if the free chlorine level in the body of water is above a safe level and adding sufficient DMH to the body of water to bring the free chlorine down to a safe level.
Claims9
A set of dispensing cartridges for placing in a back-to-back condition in an inline dispenser comprising:
- a first dispensing cartridge having a bottom inlet and a bottom outlet and containing a time dispensable chlorinating agent therein;
- and
- a second dispensing cartridge having a bottom inlet and a bottom outlet and an immediate dispensable DMH therein in a sufficient amount to increase a concentration of DMH in a body of water to a level that reduces a free chlorine level therein to a range of 0.5 ppm to 1.0 ppm.
An outdoor swimming pool free chlorine maintaining dispenser for use in an outdoor swimming pool body of water that has been sanitized with a chlorinating agent to render the body of water safe for human immersion and subject to a periodic bather load and environmental conditions, the free chlorine maintaining dispenser including:
- a first housing having a water accessible compartment containing a chlorinating agent releasable into the body of water to maintain a total chlorine level in the body of water above 4 ppm;
- a second housing having a water accessible compartment containing a source of DMH dissolvable in said body of water to maintain a level of DMH in the body of water above 10 ppm while maintaining a level of free chlorine in the body of water between about 0.5 to 1.0 ppm.
A swimming pool free chlorine maintaining kit for use in an inline dispenser of a swimming pool body of water that has been sanitized with a chlorinating agent to render the body of water safe for human immersion and subject to a periodic bather load and environmental conditions, the swimming pool free chlorine maintaining kit including:
- a first dispensing cartridge having a bottom inlet and a bottom outlet and an immediate dispensable DMH therein in sufficient amount to bring a DMH level in the swimming pool body of water to at least 26 ppm;
- and
- a second dispensing cartridge having a bottom inlet and a bottom outlet and containing a time dispensable chlorinating agent therein to bring a total chlorine level in the swimming pool body of water when containing at least 26 ppm DMH to between 3.0 and 10 ppm total chlorine with the DMH level maintaining a free chlorine level in the swimming pool body of water to a range of 0.5 ppm to 1.0 ppm free chlorine.
