Design a Portable Photovoltaic - Reverse Osmosis Unit for Brackish water As Pathway to Develop Remote Communities

Abstract

In this paper, the operation design of a portable unit for PV RO system for small communities was studied with direct conducting with solar panel and without batters storage system. In this paper the system configurations will be without batteries. In all conditions assessed, the unit showed good performance. The test rig, indicated that the unit comfortably produced at 8.5 l/h with 500 ppm feed salinity, 7.73 l/h with 1000 ppm feed salinity, 5.99 l/h with 1500 ppm feed salinity, 4.69 l/h with 2000 ppm feed salinity, 4.45 l/h with 2500 ppm feed salinity, 4.25 l/h with 3000 ppm feed salinity Sequentially with little work input from an operator. The energy consumed at varies salinity input test as 1.12 Kw.h/m3 with 500 ppm feed salinity, 1.34 Kw.h/m3 with 1000 ppm feed salinity, 1.71 Kw.h/m3 with 1500 ppm feed salinity, 2.20 Kw.h/m3 with 2000 ppm feed salinity, 2.33 Kw.h/m3 with 2500 ppm feed salinity and 2.49 Kw.h/m3 with 3000 ppm feed salinity Sequentially. The unit is easy and efficient to operate without batteries storage and with little regular maintenance. It is not practical to conduct a continuous monitoring of the system. So it needs to operate using automatic control system. In all the conditions assessed, the unit showed good performance. It is clear that the dissemination of this technique is made easier and improves efficiency to be more common.
