Boron removal from seawater reverse osmosis permeate: A Hasse diagram analysis of current technologies

The high demands for desalination of seawater in the past few years have forced manufacturers to evaluate new potential technologies for boron removal. This work examines the production options by the analytic hierarchy process (AHP) model. According to the AHP model and the Hasse diagram technique, derived from the theory of partially ordered sets, the permeate split and the use of ion-exchange in series is an open new area for a new expertise.

► RO technologies are classified according to the number of stages and passes.
► This study uses the analytical hierarchical process and the Hasse Diagram Technique.
► Eight technologies were examined.
► The permeate split and the use of Ion-Exchange in series are promising strategies.
