Which risk increases near coastal desalination plants employing intake systems within slow-rotating ocean gyres?

💡 Explanation

Entrainment of higher than permitted salinity fluids is a leading constraint in desalination operations, specifically when constrained by existing slow-rotation gyre patterns. The 'Ekman transport' spirals recirculate water which causes feedback loops of hypersaline water, because concentrated brine returns to the intake rather than dispersing. Therefore the salinity level quickly rises nearby; rather than being diluted effectively by ambient currents.
