Ionic movement based desalinator

Students of Pondicherry University , L. R. Ravindranath, S Abilash Varan, M. Logesh, S. Arvindh won the award for developing a prototype of Ionic movement based desalinator. They carried their project work under guidance of  Dr. S. Anbumalar.

Nowadays, mostly coastal areas are in the shortage of drinking water. The areas up to 10 kms from the sea shore are affected by the sea water intrusion and getting high saline groundwater.

This is the major issue in our nation in the supply of drinking water to the people and the inability to supply water to the process industries. This leads to the public health issues, damage of economic development etc..There is an technology called reverse osmosis to reduce salinity, this technology is at the high cost of installation of equipment and RO membrane filters. The yield is also very low. In our proposed method, the filter membrane is replaced by electric polarized electrodes. The principle involved in this proposed system is electrolytic ionic moment towards the opposite charges of the electrodes.The working concept of the system is the water flows, as the water fed into system through a pipe line which is split into two directions, upward and downward flow. The salts coming from feed water flow are diverted into downward flow using the concept of electrolytic ionic movement to the opposite charges of the electrode, which are fixed in downward water flow pipeline part. The downward flow water with ions of salts is drained as reject by utilizing the gravitational force. The upward flow left free from the ions of the salts, this outlet is collected as product.
