“…Recently, using the Delft3d model (Deltares, Netherland) at the study area, some preliminary analysis of the environmental impact assessments of circulation characteristics at the desalination plant near the Yanbu region was reported in [23]. Globally, there have been many studies carried out based on numerical modelling to study the dispersion characteristics of thermal and brine discharge from desalination plants [24][25][26][27]. Specifically, for the Red Sea coast, the dispersion of far-field characteristics, the extent of dilution, and the hydrodynamic circulation pattern near the disposal location were characterised with the help of a 3D numerical model [23].…”

For any coastal desalination plant, the most effective and practical way to dispose of their brine is to thermally discharge it into the sea via outfalls at some distance from the coast. This study focused on the environmental impacts associated with brine and thermal discharge arising from seawater desalination plants at Yanbu, Saudi Arabia, on the southeastern coast of the Red Sea. The impacts associated with recirculation patterns and dispersions were investigated with the calibrated three-dimensional numerical model Delft3d. The environmental impact assessment and the process of identification and characterisation could help improve strategies for better planning and management of the technological solutions related to desalination. Analysis of the model simulations for the different seasons also suggested that around the outfall location, the magnitude of the flow was always high when considered together with the presence of seasonal eddy circulations. Although the tidal flow is lower, the ambient current and wind cause the far-field discharge to spread along the north–south direction during the winter and summer. The thermal and brine dispersion and environmental compliance were assessed in terms of the extent of dispersion. The well-mixed environment caused more rapid dispersion. From the impact level assessment perspective, the study indicated rapid dilution and dispersion of the wastewater at the study region. The present offshore outfall and further offshore locations were far enough to ensure quick dispersion.

The assessment of environmental parameter along the desalination plants in the Kingdom of Saudi Arabia

The Kingdom of Saudi Arabia obtains the most desalination water from the Red Sea. In Saudi Arabia, 14 desalination plants receive water from the Red Sea, and three are located in the country’s east and rely on the Arabian Gulf. The study has observed 16 desalination plants out of 17 desalination plants in the kingdom. Most of the desalination plants in Saudi Arabia currently use the advanced technologies to produce potable water with less impact on the surrounding environment. The current study examined the variation of hydrographic parameters along all available desalination plants in Saudi Arabia. This is the first inter-annual database of hydrographic parameters in the last 4 years. The peak salinity was measured at the Duba desalination plant in 2020, and it was 67.2 ppt. During 2018, the Azizia desalination plant reported the lowest value of 36.8 ppt. The maximum temperature recorded at the Qunfudah desalination plant in 2019 was 34.6°C. In 2017, the minimum temperature was 19.1°C at the Jubail desalination plant. The level of dissolved oxygen and pH were likewise not significantly changed along the brine outflow and in the outfall, in contrast to temperature and salinity. On the basis of 4 years’ of data from observed desalination facilities, the current study sheds light on the less environmental impact with regard to hydrographic factors.
