Abstract

Abu-Taraba Desalination Plant uses multi-effect evaporation technology, which has received great attention in the past few decades, and has also introduced steam pressure technology to produce water. The capacity of the station is approximately 40,000 cubic meters per day. This study aims to determine the quality and operational efficiency of produced water from 2017 to 2019. The physical and chemical parameters included (PH,) T (temperature), NTU turbidity, Taste, Odor, electrical conduction (Ec), Total dissolved salts TDS, (T.H) (total hardness), T-ALK as CaCO3, magnesium (Mg), (K) potassium., Fe, (Na) sodium, (K) potassium and (RC1) residual chlorine were used for assessment of water quality. At the same time, determined the operating efficiency, an equation is used, which depends on the actual water volume and the volume production in the "perfect" state from 2017 to 2019. The results showed the evidence for desalination plant's high efficiency in producing water with high specifications compared to the Libyan standard limits, guidelines for drinking, and WHO specifications. While, the average operating efficiency of Abu-Taraba Desalination Plant during 2017,2018 and 2019 were 42.6% ,21.6% and 13.38 % respectively. In fact, the operating efficiency ratio was very low in 2019. Therefore, it is necessary to make recommendations to support the technical requirements of Abu-Taraba Desalination Plant to carry out the necessary maintenance of the 82-83 production units to achieve the goals and meet the needs of Abu-Taraba Desalination Plant.
