Abstract:
A method and apparatus for obtaining a solution from a solid product in contact with a liquid is provided. A solid product is housed within a dispenser. A liquid is introduced into contact with the solid product. The solution formed between the solid product and the liquid is collected, and a makeup liquid can be added thereto to further dilute or control the concentration of the formed solution. The amount of makeup liquid added to the solution can be controlled based on the temperature of the liquid to provide an automatic, continuously variable amount of liquid added to the solution. In addition, a method of providing a pressure independent control of the makeup liquid is also provided.
Abstract:
A method and apparatus for obtaining a product chemistry from a product and a fluid is provided. A product is housed within a dispenser. A fluid is introduced through a manifold diffuse member having a plurality of ports. A cover is positioned adjacent the manifold diffuse member and includes a plurality of ports. The cover is able to be adjusted, for example, by rotating the cover, to align and un-align the manifold diffuse ports and the cover ports. This adjustment controls the flow characteristics of the fluid through the manifold diffuse member and cover to control the characteristics of the fluid in contact with the product. The adjustment of the cover to control the flow will provide a generally consistent concentration and erosion rate based upon known relationships between a characteristic of the fluid and the flow of the fluid in relation to the product.
