Thin Membrane, High Ionic Conductivity
Ionomr membranes have high ionic conductivity and are thin in comparison to traditional membranes used in electrodialysis systems. Together, these properties enable considerable reduction in power consumption – especially at high total dissolved solids (TDS). Combining superior efficiency and chemical stability, our materials open up new industrial markets in both high and low pH waste streams.
ED is a membrane separation process that uses an electrical potential difference as a driving force to move salt ions in solutions.The membranes are selective and only permit the passage of either anions or cations but not both.Thus, separation is due to charge rather than size differences.Electrodialysis is based on the principle that most salts dissolved in water exist as ions (cations such as Na+, Ca2+ or Mg2+ and Anions such as Cl–, CO32-).
Our cation and anion ion-exchange membranes can be placed in an alternating pattern between the anode and the cathode of a direct current source in order to efficiently remove substances in a selective manner.
