The LIFE DREAMER project aims to develop a more efficient reverse osmosis desalination solution that enable the recovery of resources. The results of the ACCIONA-led project show increased overall conversion rates, reduced cleaning effluent volume and lower biofouling in RO membranes, thanks to advances in pretreatment.
Desalinated water has become a valuable alternative to freshwater and its quality makes it suitable for agricultural and industrial use, as well as for human consumption. Due to its performance, reverse osmosis (RO) is the most widely-used desalination technology in large-scale desalination facilities worldwide.
Despite the need for RO and the multiple benefits of its implementation in seawater desalination, there is still room for improvement. R&D&i mainly focuses on reducing brine production, specific energy consumption and the use of chemical products. In addition to seeking these reductions, the LIFE DREAMER project, coordinated by the ACCIONA Water Business, aligns the desalination process with the Circular Economy. The project considers seawater to be a source of resources that can contribute to the achievement of Sustainable Development Goal 6, which seeks to Ensure availability and sustainable management of water and sanitation for all.
LIFE DREAMER solution
The objective of the LIFE DREAMER project is to develop and demonstrate a highly resource-efficient desalination concept
that achieves an increase in the conversion rate of the RO desalination process, consumes less energy and chemicals, and enables the recovery of compounds currently not recovered from seawater.
