Abstract: A dialyzer reprocessing device and method are disclosed. The device and method are of the type which include a dialyzer and means for cleaning the dialyzer by treatment with fluids. Included is a treating device for modifying the fluids prior to introduction into the dialyzer. The treating device includes means for directly injecting into the fluids electromagnetic radiation having a preselected frequency through a nonelectrically insulated conductor.

Abstract: Beverage brewing and/or warming systems benefit from water treatment and, in some cases, the elimination or reduction of the amount of AC heat heretofore provided for such devices. Water treatment is provided in the present invention by using magnetic treatment or electromagnetic treatment by direct injection in the fluid stream or a combination of such water treatment systems. Treatment preferably occurs prior to mixing of the heated brewing fluid and the beverage powder, but improved brewing also results from treatment at the discharge side of the brewing container, e.g. the discharge of a filter holder. Improved taste and a reduction in the amount of coffee used to obtain a desired taste level results from such treatment, and the holding qualities are also improved. The bitter taste resulting from extend holding periods can be minimized or eliminated. Magnetic treatment may employ a multi-magnet concept to create sharp field boundaries, or other magnetic water treatment devices.
