Abstract: A chemical dispensing system broadly including a mounting ring and a dispenser apparatus. The mounting ring securely attaches the dispenser apparatus to a water return jet in a swimming pool or spa. The dispenser apparatus broadly includes a connector ring, a screen, a housing, and an adjustable basket. The connector ring fastens the dispenser apparatus to the mounting ring. The screen is removably attached to the housing. The adjustable basket nests inside the housing and includes a tab that protrudes through the housing sidewall. The tab is used to rotate the adjustable basket within the housing, thereby regulating the sanitizing chemical dispersal rate. Pressurized water from the return jet flows across the surface of the screen, creating an upward-rising current within the dispenser apparatus. The sanitizing chemicals in the adjustable basket dissolve as the water flows upward through and exits through the screen of the dispensing apparatus.

Abstract: A method for dynamic dosing of disinfectant solution in a medical device reprocessing system includes calculating a volume of an initial dose of concentrated disinfectant solution for dilution to make a first in-use disinfectant solution. The initial dose of concentrated disinfectant solution is diluted with diluting fluid to make the first in-use disinfectant solution comprising a target concentration of disinfectant agent. The first in-use disinfectant solution is applied to a medical device. A concentration of the disinfectant agent in the first in-use disinfectant solution is then calculated. The actual concentration of the disinfectant agent in the concentrated disinfectant solution is then calculated based upon the concentration of disinfectant agent in the first in-use disinfectant solution. It is then determined whether a volume of a second dose of concentrated disinfectant solution is increased or about the same as the volume of the initial dose to make a second in-use disinfectant solution.
