- Membrane defined as a thin layer semi permeable material which as filtering apparatus based on the physical characteristic. Whereas electro dialyses will be a filtration process electrochemically with ions move through selective cation-anion membrane, from the light solution to the heavy solution because of the existing the electrical co current. The variable of the research done are intake concentration, electrical current voltage and time. The result of the research indicated that the best result for potassium ion (K) are 57.353,55 ppm concentration intake, 2,3 Volts current voltage and 150 minutes time and 98,18% rejection obtained. Whereas the calcium ion indicate at the 4.938 ppm, concentration intake 2,9 Volt current voltage and 30 minutes time, and 98,93% rejection obtained. Keywords : membrane, cation, anion, voltage, electro dialyses
