Experimental characterization of a Reverse Osmosis desalination process fed by hybrid power source

A brackish water Reverse Osmosis (BWRO) desalination unit is studied in this paper. This unit is designed to be fed by a renewable energy based on hybrid source (wind and photovoltaic: hybrid system) with/without storage battery. The energy will be directly transmitted to the motos-pump of the BWRO process. An appropriate energy management starts from the understanding of the BWRO desalination process with its energy consumption. To optimize the energy transfer towards the load, it is useful to study the mechanical and the hydraulic system behaviour. Experimental characterizations of the motos-pumps and hydraulic load are elaborated from which significant results are drawn.
