ZERO LIQUID DISCHARGE DESALINATION: BRINE TREATMENT BASED ON EDM AND VALUABLE COMPOUND RECOVERY

The main objective of ZELDA project is to demonstrate and disseminate the technical feasibility and economical sustainability of decreasing the overall environmental impact of desalination systems for freshwater production by adopting brine management strategies based onthe use of electrodialysis metathesis (EDM) and valuable compound recovery processes with the final aim of reaching a zero liquid discharge (ZLD) process. The project duration is 4 years (July 2013 - June 2017). The second half of the project is focused on the demonstration of the new technology in two desalination plants located at Almeria (seawater desalination) and Málaga (brackish water desalination). The project will include activities to validate and optimaze the technology at laboratory scale, to design the best strategy for the recovery of valuable compounds and the evaluation of of the environmental and economic impact of the technology.
