Abstract

In this study, the operation parameters of the developed brackish solar –wind reverses osmosis unit (BSWROU) were limited. As feed water pressure, feed water salinity and feed water pH were constant. The feed temperature was the only operation parameter changed due to ambient temperature changing. Thus, the effect of feed temperature on different parameters was considered. However, due to the huge data recorded for the unit, the performance was evaluated for some months of year 2012.  Theses months were elected to represent winter, spring, summer, and autumn seasons. These months included January, April, July and October. Also, the performance was evaluated as average values for all criteria for all year. The performance of the unit was evaluated using different criteria. These criteria are energy consumption for producing fresh water (kWh/m3), recovery percent (%) and concentration factor (%). The average values of these criteria during operation in year of 2012 were 2.7 kWh/m3, 44.7% and 1.82 %, respectively. It is evident that these values demonstrated good operation of BSWROU.
