| Abstract | ||
| In the last decades more countries have experienced water scarcity problems thus pointing at alternative non-conventional sources of fresh water. Sea water desalination has proven to be a reliable and economically sustainable water resource since the second half of the 20th century. The direct solar radiation and solar energy concentrator (Solar Parabolic Trough (SPT) was used in this study. Parabolic-Trough Collector (PTC) is a linear-focus solar collector, basically composed of a parabolic-trough-shaped concentrator that reflects direct solar radiation onto a receiver or absorber tube located at the focal line of the parabola. The Parabolic Trough is tracking the sun using simple mechanism to collect the highest amount of solar radiation by optimum angle. Representative samples of saline water from El-Tamsah lake in Ismailia, the Mediterranean sea at Alexandria and the Red sea at Ain sokhna with salinity 31680 mg L-1, 33920 mg L-1 and 36480 mg L-1 respectively after treatment with PTC, the salt concentration at El-Tamsah lake sample was 326 mg L-1, while at Alexandria sample was 1036 mg L-1 and at Ain sokhna sample was 652.8 mg L-1. The results showed that the removal % of salts from El-Tamsah lake sample was 98.9%, from Alexandria sample was 96.9 % and from Ain sokhna sample was 98.2%. The result showed that the physical and chemical properties of saline water after treatment became suitable for agricultural cultured barely used in production as green fodder. | ||
