Figure 1: Operating desalination capacity from 2015–2019 and expected operating desalination capacity from 2020–2024
Figure 2: A process diagram for a typical brackish groundwater plant comprises: groundwater pumping, pretreatment, electricity-driven (e.g., pump or power supply) desalination, brine disposal, post-treatment, and distribution stages.
Figure 3: A schematic drawing of the RO desalination mechanism. An applied pressure forces water to flow from the high to the low solute concentration side.
