Capacitive Deionization Based Water Desalination System by using Solar Charge Controller

This paper focuses on addressing the issue of portable water scarcity, prevalent in various part of the world. There is a need to employ various expensive methods to transform the brackish water to standard potable water. The traditional methods of brackish water desalination deployed, namely the Reverse Osmosis Technique (RO) and the distillation processes are expensive in implementation and operation. This paper introduce a new concept “CAPACITIVE DEIONIZATION” to solve this problem. It is an energy efficient technology that provide an ideal alternative solution to this problem. In this technique remove the salt ions from the brackish water instead of removing pure water from brackish water like in the conventional reverse osmosis system. Thin film composite membranes of AEM Type-1 and CEM Type-1 are employed for collecting the respective ions which are separated by means of application of low value of dc voltage. It requires the usage of significantly less direct current energy for operation. This introduced system is enhanced by the utilization of solar energy so as to incorporate the most abundant renewable energy source available. This model which exhibits extreme potential of application mainly in remote locations which are devoid of proper access to conventional sources of energy and WHO specified standard potable drinking water.
