Solution of this double problem, UF/MF fouling on average to bad surface seawater and biodegradable
organic matters removal, can be found in the treatment line, enhancing the UF/MF treatment by adding a precoagulation/
settling of flotation. The benefits of this association of technologies are multiples, as it was developed
for the treatment on surface water one decade ago for drinking water production. Moreover, the benefit of the
coagulation/separation on the design (filtration flux) and operation (frequency of cleaning, membrane life
duration) can significantly improve the economical balance of the process. It also allows a definitive advantage
