Those systems require a significant place on the ground, but, in addition to an easy and a cheap exploitation cost, they also make possible aggressive CO 2 and hydrogen sulfide (H 2 S) removal. There are also pressure systems, which in addition to their compactness, make possible to treat water whose Fe 2+ concentrations between 7 and 10mg.L -1 .
