Abstract

Context

o A global context of drought and water scarcity in Morocco : development of an ambitious desalination investment program for water production (mining/chemical activities, drinking water supply, agriculture areas).

o OCP Green Water’s ambition for 2027 of 560 Mm3 of desalinated water (Jorf Lasfar, Morocco)


In the field of desalinated water :

o Membrane fouling is a major constraint in Seawater Reverse Osmosis (SWRO) performance

o Need to understand deposit composition to design greener antifouling solutions
