delivering a hygienically pure effluent and by exhibiting a very high operational reliabil-
ity. Advanced MBR wastewater treatment technology is being successfully applied at an
ever-increasing number of locations around the world.
In this chapter, the authors have covered several aspects of MBR, with an exhaus-
tive overview of its operational and biological performance. Different configurations and
hydraulics of MBR are presented, with attention given to the fouling phenomenon and
strategies for reducing it. Also, the high quality of MBR effluent is discussed, whereas
in comparison with CAS removals of organic matter, ammonia, phosphorus, solids, bac-
teria and viruses are significantly enhanced. Emphasis has been given to the improved
capability of MBR to remove organic contaminants present at trace concentration levels
(ng L
–1
, µg L
–1
and mg L
–1
), which to the authors’ knowledge represents a first attempt to
summarize the published literature on this subject. Finally, advantages and disadvantages
of MBR over CAS are concerned. In conclusion, MBR represents an efficient and cost-
effective process that copes excellently with the growing needs for transforming wastew-
ater into clean water that can be returned to the hydrological cycle without detrimental
effects.
