sustainable water treatment technologies in the 2025 global
Pretreatment plays the critical role of removing source water constituents, like sediment and microbes, which could hinder the downstream reverse osmosis (RO) desalination process. While some source waters require negligible pretreatment, others like surface waters, require rigorous treatment to protect the RO process operation.
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.
