Abstract: A microwave chamber for drying dialysis filter cartridges, cartridge filters and other closed filter systems. The microwave chamber has separate regions of high and low microwave absorption. The high energy absorption regions are in the central region of the filter where the bundle of hollow fibers or filter material is located. The low absorption areas are the microwave sensitive end regions of the filter module. To dry the wet filter module, the microwave frequency with the highest converted power is applied, and as the filter dries, the reflected microwave power is continuously determined and kept as low as possible by tracking the microwave frequency. The water is simultaneously discharged from the module. The process allows fast and gentle drying of filter cartridges and other closed filter units such as candle filters, and eliminates accidental overheating of the temperature-sensitive end sections of filter housings and modules with the seals and adhesives.
