MIT and Cadagua collaborate on brine recovery project in water treatment plants


Brine recovery project cadagua and MIT
The R & D Department of Cadagua, together with the Innovation Department of Ferrovial, has once again collaborated with the prestigious Massachusetts Institute of Technology (MIT) on a Brine Recovery project, which deals with the recovery and valuation of products from the desalination of seawater. The team of researchers that included Professor John H. Lienhard of MIT, Amit Kumar and Jaichander Swaminathan, along with R & D personnel of Cadagua, Alicia Gómez, Javier Arrieta and Francisco del Molino, and from Ci3, Javier Murillo, installed the pilot plant that combines nanofiltration and electrodialysis technologies through bipolar membranes for the production of soda from the brine, in the laboratory of the Valdelentisco desalination plant, owned by Acuamed. This project is part of the Cadagua strategy for the optimization of resources and the strengthening of the circular economy in its facilities, with the aim of:
  • Reducing the operational costs of the desalination plants through in-situ generation of chemical reagents from the brine.
  • Mitigate the environmental impact of brine discharges.
  • Reduce the global carbon footprint of the facilities by reducing the transport of chemicals.
  • New business opportunities for the by-products generated.
