InnoDI Water Treatment Pvt. Ltd. has developed a very innovative water treatment technology that can treat ground or surface water containing high dissolved salts and toxins such as fluorides, heavy metals, Arsenic, Nitrates, Bacteria etc. to produce clean drinkable water meeting WHO standards.
Traditionally ground water treatment is done using Reverse Osmosis Technology. This technology wastes lots of water during treatment, uses much power and chemicals and has a high operating cost for delivering drinking water
The technology from InnoDI is called Capacitive De-ionization (CDI), which is an excellent alternative to RO technology. This is a high recovery system where water wastage is just 20% as against 70% from a RO system. It does not use any chemicals, consumes very low power and has the lowest operating cost for treating water when compared to any other system in the market today. The unique features about this product are:
The system comprises “CDI Cells” which has several electrodes stacked in a compact case. Water is sent through these electrodes 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 occur. The result is the partial or total demineralization of the 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.
Water is sent at a low pressure through the electrodes. A low voltage is given, and the ions get attracted to opposite charged electrodes.Hence removed from the water .
Electrodes become saturated because of many ions sticking to it. then system automatically changes the polarity. The ions sticking to the electrodes fall off resulting in the drain.
The water with the concentrated salts gets out of the system as drain. Once these salts are removed, the Polarity is reversed and the cycle to remove ions starts again (Step 1).
Rich and deep understanding of 12+ years on how CDI behaves and works, have helped 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 …
