What is the role of high capacitance electrodes?
High capacitance type electrodes also referred to to as super capacitors or ultra-capacitors have very large ion absorption capacities and can hold about 10 billion times more ions than a metallic plate electrode. Our high capacitance electrodes generate the electric fields needed without electrode reactions and thus function without generation of gases (a dominant issue in standard electrodialysis systems) and do not succumb to corrosion effects that reduce the life of standard metallic electrodes. This feature practically eliminates the need for constant monitoring and adjustment of electrode compartment solutions, eliminates the need for gas disposal and reduces maintenance costs and down time for electrode replacements.
What are the consequences of varying the flow rate?
Unlike reverse osmosis (RO) systems that have a set flow rate and fixed energy consumption per cubic meter of product water, the flow rates for Ionic Solution’s C-EDR systems and the corresponding energy consumption per cubic meter of desalinated water could be reduced. This means that the cost of water could easily be reduced when the demand is less.
Are there membrane fouling issues with C-EDR?
Ionic Solution’s C-EDR technology inherently also uses reversing currents that helps to clean the membranes by preventing biofouling and plugging on the surface. Reversing the electric field has been proven to preserve the membranes and prevent plugging that could restrict flow.
What is the lifespan of C-EDR equipment?
The equipment can run for over 10 years with little to no effects to the unit, based upon industry research and experiences to date with standard electrodialysis equipment.
