Brine valorization plants are the next step in the evolution of desalination technology, which opens a new horizon for wider use of desalination as a baseline source of drought-proof and environmentally and fiscally sustainable water supply.
Over the past decade, the desalination industry has developed a number of brine concentration and mineral extraction technologies which enable the generation of commercially valuable products from brine.
Figure 1 presents the typical configuration of brine valorization plants – it includes membrane nanofiltration (NF) system for the separation of the brine from the desalination plant into two streams and subsequent concentration and crystallization of these streams into individual minerals.
