STUDY OF THE QUALITY OF WATER DESALINATION BY REVERSE OSMOSIS METHOD

Abstract

This study aims to evaluate the quality of desalinated water by the reverse osmosis process. The samples were collected in a 5-liter bottle from three different desalination factories (Alwaha, Alnawras and Alferdos) before entering into the factory (incoming water) and after leaving the factory (outgoing water). Then, the desired tests were carried out. The results were recorded for the incoming water for a PH ranged between 7.3 and 8.13, total dissolved salts between 3770 and 5801 mg/L, electrical conductivity between 4938 and 7332 µcm/s, nitrates  between 19.8 and 27.6 mg/L, manganese  between 0.07 and 0.12 mg/L and sodium between 930 and 1334 mg/L. And for  the outgoing water, the results were recorded for pH ranged  between 6.7 and 8.09, total dissolved salts (122.4-215.1) mg/L, electrical conductivity (193-330.1) µcm/s and nitrates (8.9-18.6) mg/L, manganese (0.03-0.05) mg/L and sodium (25.9-71.7) mg/L. These results showed that the specifications of the outgoing water samples satisfy the Libyan and the World Health Organization specifications.
