Abstract
The aim of this work was to describe the operation of the desalination unit at the thermal power plant of Cap Djinet (Eastern Algeria) and the management and characteristics of the brine. The desalination unit at the thermal power plant of Cap Djinet (Eastern Algeria) operates a multi-stage flash distillation (MSF). The desalinated water passes through a demineralization step to obtain water with characteristics according to a boiler feed water at high pressure. During rejection, the brine is subjected to dilution with cooling water. This causes a decrease in the brine water salinity from 70 to 40 g/l and conductivity of 85 to 56 ms/cm which is equal to the conductivity of seawater. For other parameters, we found the same results as seawater based on the results of various analyses, we can say that the rejection of brine diluted station Cap Djinet is similar to seawater as probably it does not affect the receiving marine environment.
