Issues like: Demo size. Total area required (m2)? Installation and testing period duration? Seawater requirement: flow and volume/day required (Pozo Izquierdo has a beach well – Atlantic water 38 g/l, SDI<2). Electrical grid connection required? – if yes, power required (kW) and energy consumption (kWh). Recovery rate, brine produced (volume and quality), brine discharge (flow (m3/h) and nominal operation daily estimation (h/day). Possible impacts that could generate your technology, use of chemical products in the desalination process. Renewable energy technology to be installed (kW, land requirement, height, etc.). Any other info you consider relevant for your testing.
