What is Capacitive Deionization
Capacitive Deionization (CDI) is a technology for removing salinity from water.This innovative technology is used to desalinate water without using resin or membrane filters. It does not require chemicals to treat water and uses very low poer to separate salts in water.
How it Works
The system comprises of “CDI Cells” which has several electrodes stacked in a compact case. Water is sent through these electrode at a very low pressure and as water flows through these electrodes a voltage difference is applied (forming a capacitor) between them to disassociate ions present in water.
As water moves through these electrodes, a direct current at a potential difference of 1.6 Volt is supplied. This creates an electrostatic field that attracts the ions dissolved in water to the electrodes. Operating as low voltages, electrolysis and gas production will not occure. The result is the partial or total demineralization of water.
The electrodes behave like those of a normal condenser. At a certain point, the ions will cover the whole surface of the electrodes saturating them. When this occurs, the system senses the potential difference and automatically reverses the polarity of the electrodes. By doing so, the ions that are stuck to the electrodes gets disengaged. The result is a high concentration of dissolved ions that are now sent to drain.
Ions Removal Process
Ion Removal
Water is sent at a low pressure through the electrodes. As they pass a low voltage is given and the ions get attracted to opposite charged electrodes. The water which is void of these salts and metals come out of the system.
Regeneration
With more and more ions sticking to the electrodes, they become saturated – when this happens, the system automatically changes the polarity. The ions sticking to the electrodes fall off resulting in the drain.

Benefits of CDI
Retention of essential Minerals in Water
CDI provides a unique benefit where by altering the voltage and flow we can control the extent of ion removal. With this we are able to retain essential minerals that are required for body - while taking out harmful toxins.
Low Operating Cost
CDI cells has a life of 4-5 years combined this with low energy we are able to deliver water a low operating cost.
Low energy use
Our CDI system requires less energy for its operation. All its operation is using DC power. The smart electronics ensures optimal usage of current required for its operation. This results in low energy and carbon emission.
Low water wastage
The maximum water wastage in our CDI system is 20%. This results in long-term conservation of ground water.
Environmentally Friendly
CDI does not use any chemicals for treatment. The electrodes are made of carbon materials that are safe for discharge.
Why are we Unique
The promoters of InnoDI have been working on CDI since 2007. Using this deep understanding on how CDI behaves and works, we have been able to develop many innovations around it that ensures the technology works efficiently and optimally for various applications.
The innovations that makes our CDI solution unique are...
