We offer a new, efficient technology for the removal of hazardous ionic contaminants from surface and ground water sources, the ion exchange membrane bio/chemical reactor (IEMB). It is based on the Donnan Exchange principle according to which, driven by the proper concentration gradients, toxic ions such as perchlorate, nitrate, fluoride, arsenite, arsenate and more, can exchange through an ion exchange membrane with other, non-hazardous ions (such as chloride) and transport from contaminated water to the other side of the membrane where they can be eliminated by microbial processes (such as nitrate and perchlorate reduction to the non-hazardous nitrogen and chloride), or by chemical processes (such as precipitating fluoride and arsenate), leaving the treated water free of the contaminating ions and the possible back contamination by components from the elimination processes. Main objective is the adaptation of the process to India's needs for safe water for domestic applications. For that purpose we propose to install one or two IEMB units in appropriate sites in India for studying the operational parameters on 'real' contaminated water sources.
1. Bringing water quality to the level that meets the international standards for safe water use with respect to the above mentioned ionic contaminants.
2. Testing the IEMB for optimum operational parameters such as removal efficiency, energy requirements, prolonged operation in the field and maintenance requirements.
3. Testing the IEMB with respect to ease of operation in remote areas and adaptability to the capabilities of local community in these areas
