The focus for developments will be in the arid state of Gujarat, where surface water resources are very scarce. We will develop novel batch-reverse osmosis technology for a 10-fold reduction in specific energy consumption with high fractions of water recovery (80%) reducing /m3 operating costs to below €0.35/m3 (<30 rupees/m3). Forward osmosis will be developed and piloted for use in wastewater recovery applications including hybrid arrangements with reverse osmosis for further reduction in energy consumption. These solutions will be demonstrated in small-scale rurally relevant low-cost systems for brackish groundwater treatment for use as safe drinking water, which will be extended to include phyto-technology solutions for rural domestic wastewater treatment.
