An adapter including at least one wall defining a chamber, at least one opening within the wall, and a water-soluble additive coating at least a portion of the wall such that fluid flowing from one opening through the chamber dissolves the water-soluble additive within the chamber.

Provided is a washing machine capable of improving solubility of a powder detergent that remains without having been dissolved in mixing water contained in a tub. The washing machine includes a cabinet having a detergent supplier, a tub arranged in the cabinet to be connected to the detergent supplier and containing mixing water in which washing water supplied to the detergent supplier and a powder detergent are mixed, a drum rotatably installed in the tub, a circulation hose connecting between the tub and the drum for the mixing water contained in a lower portion of the tub to be circulated, a detergent dissolution device generating vortex current in mixing water circulated through the circulation hose to improve solubility of the powder detergent, and a circulation pump arranged in the circulation hose and configured to repeatedly supply and discharge mixing water to and from the detergent dissolution device through on/off controlling.

Provided is a method of preparing an activated mineral solution, which includes steps of pulverizing granite and/or vermiculite into a powder by grinding, subjecting the powder to an electrolysis treatment, dissolving the powder in an aqueous ammonia solution and an acidic solution to prepare a mixed solution, emitting ultrasonic waves on the mixed solution, introducing microorganisms onto the mixed solution, and neutralizing the mixed solution, in which the mineral is selected from the group consisting of Fe, Mg, Al, Ti, K, Ca, Mn, Nb, P, Na, Zn, V, Cr, Ni, Si, B, Cu, Li, Ga, Co, Sr, In, Rb, Sb, Ta, Y, and combinations thereof.

A device for packaging and dispensing a chemical product is provided. The device may include a first portion connected to a second portion. Counterpoising locking features may secure the first portion and the second portion. A support member is disposed within the lower portion and adapted to support the product. The device may include a flexible enclosure contoured to and enclosing the rigid body and the product. The flexible enclosure may enclose a portion of the housing and the product, after which heat is applied to shrink the flexible enclosure. A handle may provide for ease of installation and/or removal of the device from a solid chemical dispensing system.

The present invention pertains to a hollow fiber membrane module (5) for removing gas from an objective liquid or supplying gas to the objective liquid, comprising: a hollow fiber membrane bundle (20); and a collecting member (51) configured to collect first ends (20a) of the hollow fiber membrane bundle (20) while maintaining openings of opened end portions (22a) of hollow fiber membranes (22) of the hollow fiber membrane bundle (20), wherein the collecting member (51) has a coupling portion configured to couple the collecting member (51) to an installation object in a detachable and liquid-tight manner.

A system for mixing a liquid with a powder into a solution batch includes a hopper (20) into which said powder is deposited, the hopper (20) having a powder outlet (22) therein. A mix tank (60) is also provided having a liquid supply inlet (62), a recirculation inlet (64), and a solution outlet (66). A mix pump (40) that is in fluid communication with the solution outlet (66), the powder outlet (22), and the recirculation inlet (64) operates to mix and transfer the solution.

Disclosed is a dissolution mixer, which includes: a dissolution bath configured to accommodate a powder and a solvent for dissolving the powder; a powder input unit located at an outer side of the dissolution bath; an impeller installed to be rotatable inside the dissolution bath; and an anchor located inside the dissolution bath and having a passage of the powder inputted by the powder input unit and a powder spouting hole connected to the passage.

A brine machine comprises a salt hopper, a source of water for wetting salt in the salt hopper, a brine hopper positioned in side-by-side relation relative to the salt hopper, a filter providing fluid communication between the salt hopper and the brine hopper, a generally horizontal auger positioned in a base of the salt hopper, and an upwardly directed lift auger having a first end in operable association with an end of the horizontal auger and a second discharge end positioned above a level of brine in the brine hopper. The augers convey solid material from the base of the salt hopper and discharge the material from the machine.

A floating dispenser for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser floating in an upright condition when a dispersant is present in a dispenser cartridge of the floating dispenser with the dispenser self inverting 180 degrees in response to consumption of the dispersant in the dispenser cartridge to thereby provide a visual alert that one should replace the dispenser cartridge in the dispenser with a fresh dispenser cartridge.

A floating dispenser having an external float or an internal float for supporting a cartridge or cartridges for floatingly delivering a dispersant or dispersants to a body of water with the floating dispenser having cartridges rotationally positionable with respect to one another to control the rate of dispensing while the dispenser floats in an upright condition with the floating dispenser changing its flotation orientation in response to consumption of the dispersant or dispersants in the a cartridge to thereby provide a visual alert to replace a spent cartridge with a fresh cartridge. In addition the inventions described herein permit changing the dispensing nature of the system from a multiple dispensing system to a single dispensing system without changing the floating characteristics of the floating dispensers through replacement of a dispersant in one of the cartridges with an inert or ballast material that has no effect on the water characteristics.
