Pretreatment Needed
Technical Profile
Seawater desalination (SWRO) is a very sensitive membrane process. Silt density index (SDI) of less than 3 is necessary for proper membrane performance and life. If there is spare capacity in the sulfate removal package it can be used to provide very good water to the RO. If not, fine solids removal including multimedia filtration, cartridge filtration or a combination of both may be necessary.
