  • What is pretreatment of sea water?
  • 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.
  • Which pretreatment system is used for desalination using sea water reverse osmosis?
  • Microfiltration and Ultrafiltration processes are the most widely used pretreatment systems for Desalination using sea water Reverse Osmosis technology [, , , , ].
  • Is membrane osmosis a cost effective treatment of sea water?
  • Researchers, over the years have found that the treatment of sea water by membrane processes is the cost effective technique in comparison with other processes [1, 59]. The most important of the membrane processes is the Reverse osmosis.
  • Does pretreatment of seawater meet the water-supply standard of RO membranes?
  • The SDI values determined in the present study confirmed that after pretreatment using SBF, the seawater met the water-supply standard of RO membranes. Finally, we compared the specific resistances of the sludges generated via conventional softening and SBF.
