title: [Water purification for hemodialysis].
abstract: An electrodialysis system has been designed to purify water. It comprises two units: a preliminary preparation unit and an electrodialysis one. The system consists of columns containing zeolite, activated carbon, and ion-exchange resins. Zeolite makes water free from mechanical impurities and iron, activated carbon adsorbs organic matter and chlorine ions, ion-exchange resins soften water. The electrodialysis unit is noted for its original design. Mathematical simulation has allowed the authors to optimize the design and to make a block that makes the process continuous without repolarization, which can decant the minimum levels of salt concentrates, thus decreasing energy supply to 2 W per liter. The unit is made as a pressure filter design having the platinum-titanium electrodes and membranes MK-40 and MK-45 made in Russia. The system operates automatically. Its all components are made in Russia.
