Increasing environment protection awareness made the availability of clean water, technological, social and economicalchallenge of the 21st century. Water, is a scarce amenity not only in India but in the whole world. Most of the available wateris saline and is not potable. Water supplies are not matching the actual water needs of the society. We have beensquandering and polluting water resources since ages and are now in need of finding cost competitive newer technologies forreclaiming this valuable life-sustaining liquid. Membrane capacitive deionization is one of those prominent technologieswhich assure to be more efficient with higher water recovery and less power consumption.In this study concentration of trace metals viz. Barium, Arsenic, Lead, Chromium, Cadmium, Nickel and Boron in groundwater samples from western Rajasthan were determined using Inductive coupled plasma- Optical emission Spectrometer(ICP-OES). These metals have toxic effects on the human health; most of them are carcinogenic and can cause fatal effects ifconsumed in fewer amounts continuously for long duration. This study has also been done to assess the removal of tracemetals by membrane capacitive deionization process. Electrical conductivity of water was assessed to compare the resultswith trace metals. Certain areas of Jodhpur and Jaisalmer districts of Rajasthan state in India were selected as the studyarea. The pilot plant (CapDI) manufactured by Voltea (Netherland) was provided by InNow India Pvt. Ltd for carrying outthis study. The maximum EC was reduced by 98 %, whereas the trace metals Barium, Cadmium, Chromium and Boron wereremoved by 57%, 70%, 50%, and 74% respectively. Thus it can be interpreted from the study that Membrane CapacitiveDeionization Technology can remove the Heavy and Toxic metals up to a certain limit effectively with low powerconsumption.
