ACCIONA has launched its WITNESS project with the aim of developing a biological indicator to preventively determine the presence of agents causing fouling in seawater reverse osmosis desalination processes.

The new indicator developed by ACCIONA will provide a preventive diagnosis to adjust the operating conditions of the desalination plants, in order to minimise fouling and, therefore, its consequences on the desalination process.

Together with other operation indicators of the reverse osmosis stage, the WITNESS indicator will be integrated into an Artificial Intelligence-based fouling potential prediction tool, which will be validated in the innovation facilities of the company.
