Pretreatment processes for seawater reverse osmosis desalination systems—A review
TLDR
In this paper, the authors made an effort to understand the conventional process, microfiltration, ultra filtration, nanofiltration and integrated membrane systems for the seawater pretreatment, their advantages and limitations and the effect of the pretreated water on the performance of reverse osmosis membranes through the studies conducted by researchers as well as by considering certain case studies.Abstract:
An efficient pretreatment system forms the backbone of a sea water desalination unit using reverse osmosis process. The pretreatment of sea water is done to bring down the turbidity, microorganisms, colloidal contaminants, total dissolved solids and silt density index of the raw sea water to acceptable levels and make it suitable for the Reverse Osmosis membrane process. The two kinds of pretreatment processes used are the conventional system and the membrane systems. The present review paper makes an effort to understand the conventional process, microfiltration, ultrafiltration, nanofiltration and integrated membrane systems for the seawater pretreatment, their advantages and limitations and the effect of the pretreated water on the performance of reverse osmosis membranes through the studies conducted by researchers as well as by considering certain case studies.read more
