The Effect of Discharge Rejected Brine into the Surface Water on the coast of Port Sudan city

The general aim of this study is to focus on the effects of discharge reject brine into the surface water in Port Sudan city. It considers a baseline study in Port Sudan. Three samples of water were taken from sea land lagoon by using TCD (Temperature, Conductivity and Depth) device, and sample from open sea (Abu Hashish). All samples were collected during summer and winter seasons. The results showed a significant increase in salinity 39.13 – 49.86 , 39.91- 47.45 , 38.62 - 38.87 , 38.48 – 39.27 psu respectively, of the surface water when mixed with the discharge reject brine, this will absolutely affect the marine life. Also, the continuous discharge of rejected brine into water near the intake desalination plants will affect the characteristics of the feed water.
