Highlights:
- Nanofiltration experiments compared 3 membranes for desalination brine valorization.
- NF must be done before Ca removal stage at brine treatment for resource recovery.
- PRO-XS2 presented the highest selectivity between mono- and multivalent elements.
- Heating the brine for Ca removal jeopardizes the project’s economic feasibility.
- Total levelized cost of 1.6 €/m3 was estimated for FonsalÃa plant brine.
