Most of the Mediterranean countries suffer from water shortage due to both increasing demand and declining water quality. Rivers, lakes, groundwater resources and the sea have become more and more polluted by agrochemicals and other potentially toxic substances resulting from intense agricultural and industrial activities. Besides the necessary efforts to be undertaken to reduce water consumption, such a situation calls for innovative and cost-efficient solutions to purify contaminated water and recycle wastewater. NANOWAT project focuses on the experimentation, development and diffusion in the Mediterranean area of new technologies for efficient water treatment based on natural and modified nano-materials, using either filtration and sedimentation, photo-degradation, or their combination. The application of nanotechnologies in the field of water treatment has the potential to offer low-cost and transportable solutions in areas where it is difficult or too expensive to implement large scale water purification plants. Expected Results: • Pilot scale transportable equipments for the treatment of wastewater, grey water, pesticide contaminated water developed • Increased amount of clean water available, mainly for irrigation purpose • Reduced total energy required for water treatment • Costs for water recycling reduced by at least 20% • Professional skills increased • Enhanced availability of new technologies for local authorities and farmers associations
