Abstract: Dispensers, principally of water-treatment chemicals, are detailed. The floating dispensers may be inherently unstable in use, rotating approximately ninety degrees (from a generally vertical position to a generally horizontal one) over the useful lifespan of the chemicals initially contained within.

The dispensers also may be stacked into smaller volumes for transit and storage and need not include a separate component for flow adjustment. Rotation of its components additionally may create a “dial-a-dosage” feature of the dispenser, effectively varying depletion rate of the chemicals contained therein.

Abstract: A chemical solution dispensing apparatus uses a dissolving tank to hold a solid chemical cake. The dissolving tank delivers the chemical solution into a holding tank by gravitational flow and then to a receiving system. A liquid level sensor in the holding tank senses the liquid level of the solution and calls for water delivery through a conduit into the dissolving tank. When the level reaches a low point a circuit opens a inlet flow valve to deliver water into the dissolving tank. When the level reaches a high point, the circuit closes a safety shutoff valve in the conduit line. A pressure regulator and control relay enable the conduit line to be properly pressurized by an inlet source of water through a shutoff valve that is normally open. When the level in the holding tank rises above the high point, an alarm signal is released to initiate an audible alarm.

Abstract: A method for monitoring and adjusting the level of free chlorine in an aqueous fluid is described. In the described method, first aqueous fluid (50) substantially free of free chlorine is introduced into a suitable mixing vessel (26) wherein it contacts a solid chemical material that is a source of free chlorine and chloride ion.

Second aqueous fluid in holding tank (10) is forwarded by pump means (20) to the point of application.

Abstract: The invention provides an apparatus and method for storing and transporting peritoneal dialysate in dry or lyophilized form, and for forming a deliverable peritoneal dialysis solution therefrom. In one embodiment, a dry reagent bed, including reagents sufficient to produce a dialysis solution, is suspended in a diluent flow path through the apparatus housing.

Abstract: Apparatus and method are provided for the treatment of potable water. A non-pressurized chlorinator has a first chamber which receives solid calcium hypochlorite tablets. A portion of the potable water flows into the first chamber to produce a chlorine solution in a second chamber of the chlorinator. An eductor is connected in a potable water flow line and draws the chlorine solution from the second chamber to chlorinate the water. A third chamber in fluid communication with the second chamber includes level sensors to control the flow of water into the chlorinator. The use of pumps for injection of chlorine into the potable water supply is eliminated thereby providing a highly reliable and cost effective system. The system is particularly advantageous in that it does not rely upon the use of chlorine gas nor is it necessary to transport or store highly unstable liquid chlorine.
