UF Pretreatment For Cold Seawater RO

The main obstacle to the use of UF membranes for SWRO pretreatment has always been the high operating cost. This paper describes operational experience of pilot projects using a new membrane designed for the lowest whole-life cost while enabling the most difficult seawater to be treated using membrane desalination. This article shows how the project results can be translated into a technical and commercial evaluation of the best pretreatment option for the desalination of water from low temperature water sources. The technical design details are described for the Evides demonstration plant in the Netherlands, fed from the river delta formed by the Meuse, the Scheldt and the Rhine rivers in southwest Netherlands. It also explains the decision-making process for selection from pretreatment options for the Thames Gateway SWRO project, a plant that is fed by water strongly influenced by tidal effects.
