A method and apparatus for obtaining a product chemistry from a solid block is provided. The product is housed within a dispenser, which utilizes a liquid and a gas to erode the block and produce a concentrate solution. The liquid and gas characteristics can be adjusted in the field to achieve a predetermined concentrate level in the solution. The introduction of air into the dispenser saves water, while producing higher concentrate levels.

A non-dissolvable immersible dispensing puck in the shape of a dissolvable halogen puck when the dissolvable halogen puck is in an undissolved state with the non-dissolvable immersible dispensing puck physically interchangeable with a dissolvable halogen puck when placed in a dispenser for normally holding only a set of halogen pucks to enable a single dispersant dispenser to be converted to a dual dispersant dispenser without changing the structure of the single dispersant dispenser by placing a dispenser within a dispenser wherein only one of the dispensers may be provided with adjustable water ports.

Systems, methods, and software program products for detecting an out-of-product condition in a chemical dispensing system. An optical sensor includes a photodetector and a light source configured to generate a beam of light. The light source is positioned such that the beam of light is incident on a supply line at an oblique angle. The supply line displaces the beam of light in dependence on the refractive index of a medium in the supply line. The photodetector is positioned so that it is in the optical path of the displaced beam of light when the refractive index of the of the medium in the supply line is indicative of one of a wet state or a dry state. A detection module receives an electrical signal from the photodetector and determines if the out-of-product conditions exists base thereon.

A discharge system includes a mixing vessel and a feedstock input in fluid communication with the mixing vessel. A solvent input is in fluid communication with the mixing vessel. A discharge output is in fluid communication with an outlet of the mixing vessel to discharge effluent. A method for generating turbulence on a liquid surface within a discharge system includes supplying a mixing vessel with feedstock fluid and solvent fluid to generate a liquid mixture and a gas pocket in the mixing vessel. The method includes supplying an impinging solvent fluid through a nozzle extending from a first end of the mixing vessel to generate a roiling surface at an interface between the gas pocket and the liquid mixture and permit uptake of gas from the gas pocket into the liquid mixture.

A floating chemical dispenser is provided, which includes: a body portion having a first chamber for receiving solid chemicals, a second chamber for receiving a floating member, and at least one first hole for communicating the first chamber with an external environment, an opening is disposed at one end of the body portion, and the opening is communicated with the first chamber; and a cover, configured to close the opening of the body portion; wherein the cover is detachably connected with the body portion via a first locking mechanism, and the first locking mechanism has a locking position and an unlocking position, and is configured to move between the locking position and the unlocking position via pressing and rotating the cover by a user, so as to control locking or unlocking of the cover and the body portion. Therefore, safety performance of the floating chemical dispenser can be improved.

This disclosure discloses an upper end cover applied on a floating medicine dispenser and a floating medicine dispenser which comprises a main body and the upper end cover; the upper end cover comprising a cover body, at least one locking mechanism arranged on the cover body, and the locking mechanism comprises a pressing buckle, a reset component connected to the pressing buckle and a locking plate; the pressing buckle is movably mounted on the cover body through the reset component; one end of the locking plate, the end of which away from the pressing buckle, extends toward the main body of the floating medicine dispenser, and clamps into the main body of the floating medicine dispenser when the reset component is at the reset state so as to lock the upper end cover on the main body of the floating medicine dispenser.

An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system and a recirculation loop to the dilution reservoir for enhanced mixing of the dilute concentrate. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.

An indexable cartridge and method that is useable in either a stagnant fluid environment or in a moving fluid environment with the indexable cartridge floatable in a stagnant fluid environment and securable in a moving fluid environment with the indexable cartridge having a housing having one or more diffusion ports and a sleeve having one or more diffusion ports indexable to a diffusion port alignment through resilient yielding of the sleeve while a set of ribs inhibit lateral flow therebetween.

A method, apparatus, and system for obtaining a solution from a solid product are disclosed. A solid product is housed in a dispenser. A liquid is introduced into the housing of the dispenser to interact with the solid product to form a solution. To control the concentration of the formed solution, the turbulence of the liquid introduced to the dispenser is controlled and adjusted either manually or on a real time basis to account for varying characteristics of either or both of the solid product and the liquid. The dispenser will adjust the turbulence based on the characteristics to maintain a formed solution within an acceptable range of concentration. The concentrated solution can then be discharged from the dispenser to an end use application.
