“…For example, in Shuqaiq Phase-II Seawater Desalination Plant (212,000 m 3 /day) in Saudi Arabia, oxidation deterioration still occurred while oxidation reduction potential (ORP) was monitored and controlled at less than 300 mV with a SBS dosage. Nada et al [ 46 ] and Sommariva et al [ 47 ] confirmed that it was due to sulphite auto-oxidation with the co-existence of Cu ion, and indicated that optimization of the SBS dosage amount, chelate agent (sodium salt of ethylenediaminetetraacetic acid (EDTA)) dosage and scale inhibitor dosage suppressed the reaction.…”

Seawater desalination plants that use reverse osmosis (RO) membranes have become a core part of social infrastructure, and should be designed to meet the needs of product water quality and production capacity, while considering various environmental factors such as the seawater quality, temperature and geographical features. Furthermore, stable operation while overcoming various problems should be achieved alongside the increasing demands for energy saving and cost reduction. As no universal plant apparatus and operation technology meets these various requirements, the plants need to be customized for individual solutions. This paper reviews and summarizes the proven technologies, including their advantages/disadvantages, and points to cutting-edge technologies related to the design and operation maintenance of seawater intake, pre-treatment and the RO desalination process.

Reverse osmosis (RO) plays an outstanding role in water desalination worldwide. Performance of this technique depends on membrane fouling and the raw water seasonal variations, especially temperature and raw water salt concentration. Hence, to neutralize the impact of temperature and feed concentration on the performance parameters, the data collected from the brackish surface water plant were standardized through the use of the American Society for Testing and Materials methods. The value of this normalization is to be able to discern the performance variation which is due to the membrane aging and the membrane fouling, scaling or degradation. The present research investigates the real industrial results gathered from the first experience of brackish surface water demineralization by RO in Morocco. The results obtained evidently show that the feed water is subject to serious seasonal variations in terms of feed temperature and feed salts concentration, which noticeably affect the feed pressure, membrane permeability, and permeate conductivity. The standardized permeate flow, standardized pressure drop, and standardized salt passage show that the performance of the plant was steady all over the period of the monitoring and the observed performance decline-was due to membrane fouling.
