Abstract
Water and energy problem are the main issue that world suffer from it and tried to find
sustainable solution for it .Palestine is one of country that have these problems because of Israeli
occupation and their tough policy in water and energy sectors. One of the solutions of water
problem is to exploitation of spring water where it considers as undrinkable water. in addition, in
winter season water level is overflow which cause a flood in the streets. To solve this problem
desalination technology is used and in this system a reverse osmosis technology is used which is
powered by solar energy and it is a sustainable solution for electricity problem in rare area.
Where one stage and one pass with ECO PLATINUM 440 which is Spiral-Wound element with
polyamide thin-film composite membrane driven by 11 watt high pressure pump powered by 50
watt PV panel, the result was feasible in some of months and the other was not and it depend in
the amount of the solar radiation because there is no storage system in the system.
In this work a simple study is done for as a sustainable solution for water and energy issues also
for spring excess water. Reverse Osmosis Powered by PV has been designed as a portable device
Using WAVE and SAM software were the performance during the year and various
environmental conditions have been studied in order to determine the optimal case of this device
and the produced water flow rate with the power of the pump where the device covered only the
required flow rate only in the summer months and also DC pump could be directly coupled with
PV panel but with attention to the DC voltage otherwise controller preferred to be used and if
there is some excess power UV Purification can be used to benefit from it. This device has
several characteristic whereas it is environmentally friendly, economical and easy to use.
