Evaluation of Single-Pass Seawater Reverse Osmosis Modules and Pretreatment Techniques.
Abstract
Four reverse osmosis modules were evaluated on natural seawater at Wrightsville Beach, North Carolina. Three of the modules were run on chlorinated and cartridge filtered seawater, and all showed permeate rate declines greater than 30% per thousand hours. The fourth module, run on chlorinated, ultrafiltered seawater feed showed an average permeate rate decline of 4.7% per thousand hours of operation after 3800 total operating hours. Permeate total dissolved solids for all modules were consistently less than 500 parts per million. It was found that a high degree of filtration was necessary for the successful operation of reverse osmosis modules for seawater desalination. The use of electrolytically generated chlorine to prevent membrane biological attack (and/or fouling) and to produce chlorinated potable water without the use of any chlorine compounds was considered very successful.
