Zero Liquid Discharge desalination: brine treatment based on electrodialysis metathesis and valuable compound recovery
Welcome to ZELDA project website
Zero Liquid Discharge desalination: brine treatment based on electrodialysis metathesis and valuable compound recovery (ZELDA)
The main objective of the 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 on the use of electrodialysis metathesis (EDM) and valuable compound recovery processes with the final aim of reaching a zero liquid discharge (ZLD) process.
The project has a total duration of 4 years (September 2013 - August 2017) two of which are focused on the demostration of the technology proposed in two real desalination plants located in Almería (seawater desalination) and Málaga (brackish water desalination). The project also include activities which will validate and optimise the technology at bench scale, design the best compound recovery strategy for seawater and brackish water desalination and evaluate the environmental and economical impact of the proposed technology compared with conventional brine management strategies.
