Super Capacitor Electrodes

  • C-EDR super capacitors have been designed to carry a very large charge (over 60 Farads/gram). This proprietary design creates an electric field in the cell that efficiently separates the ions from water while preventing gas producing electrode reactions.
  • Lower energy requirements. Compared to ED/EDR systems that utilize DC electrodes, C-EDR is over 5X more efficient. This results in much lower cost desalination process.
  • Long life expectancy. C-EDR electrodes do not foul due to ion contamination (compared to Cap Deionization technology where the capacitor life is affected by ion movement into/out of the capacitors).

Osmotic Flow Control

  • This feature enables C-EDR to achieve very high recovery rates (over 90% for many applications).
  • Osmotic flow control refers to the uniquely designed internal structure of the cell, which prevents concentrated wastewater from leaking into the clean water channels. This internal structural design also manages the high osmotic pressures that create problems in other technologies.

Variable Operation

  • RO membrane cells have limited operating variability, and generally operate at optimum condition. C-EDR on the other hand, can operate efficiently across a wide range of flow capacity and salinity levels, simply by changing the capacitor power.
  • This provide operators with much more flexibility in how they run their system, in order to meet changing demands for capacity or input conditions.


Lower overall maintenance cost and energy consumption

Our C-EDR with Osmotic Flow Control technology optimizes the use of electric fields and pressures for desalination, with a lower overall maintenance cost and energy consumption requirement than both reverse osmosis (RO) and conventional electrodialysis (ED) systems.

  • Requires no consumable chemicals.
  • Operates with minimal input costs.
  • Is designed to function with little maintenance for periods of up to 10 years, translating to a reduction in operating costs by as much as 20-30%.

To meet the ever-growing needs of countries that require additional freshwater resources, C-EDR technology provides not only an economic process but operational flexibility including:

  • Variable flow rate wherein the energy consumption per m3 will also be lower when lower output rates are needed. Output flow can also be increased to meet higher than expected demands. These unique features are absent in all other technologies, including RO.
  • Handles wide range of input salt concentrations.
  • Scalable from small to large facilities.
  • Retrofit into existing desalination plants.

largest aquifers are being depleted at alarming rates. These aquifers have passed their sustainability tipping points, meaning more water was removed than replaced during the decade-long study period.
