The Brazilian experience with a photovoltaic powered reverse osmosis plant
This article describes a system that combines the technologies of reverse osmosis and photovoltaics to realize a pioneer project for drinking water supply to a rural community in semiarid Brazil (latitude 3 degrees 44'S), with a local yearly average temperature of 28 degrees C and a yearly solar potential of about 2000 kWhm-2. Two strategies are investigated: first the PV-RO (photovoltaic powered reverse osmosis) plant is equipped with a DC motor; and second, a three-phase induction motor is used. Through the analysis of the stored data the second option is chosen as the better alternative. This strategy has a specific electrical consumption (energy required to produce 1 m3 drinking water) of 3-03kWhm-3, a recovery ratio of 27% (relation between drinking water product flow and brackish water input flow) and a drinking water cost of US$12 76 perm3.
