Seawater reverse osmosis (SWRO)

Organic matter dissolved in seawater should be analyzed carefully since organic fouling is one of the main reasons for low performances of seawater reverse osmosis (SWRO) processes. Because of various ionic constitutions with high concentrations in seawater, the seawater organic matter analysis is d

The Hamma (Algeria) desalination plant, briefly described in the paper, was mathematically modelled in order to check its behaviour in an advanced phase of its design. The plant will employ 288 ERI’s PX units to recover the pressure of the brine discarded from the RO membranes. This way of recoverin

This study proposes a new operation methodology for energy saving in the Fujairah seawater reverse osmosis (SWRO) plant, as the optimum feed pressure is determined at the controlled operating temperature. To this end, two functional models were developed by genetic programming (GP) using two-year op

Energy Recovery, Inc.’s Big Rotor Pressure Exchanger is the result of over 100 years of technology development. Work exchanger devices developed for seawater RO plants are considered by many to be the most important breakthrough in desalination in the last 10 years. What has made this breakthrough p

For the last 3 years, the SWCC–RDC conducted extensive R&D work on nanofiltration (NF) pretreatment of feed to SWRO and make-up to MSF pilot plants in dihybrid arrangement of NF–SWRO or NF–MSF, also in trihybrid of NF–SWROreject–MSF, where the SWROreject from the dihybrid NF–SWRO is used as make-up
