Water Quality Analysis of the Field Seawater Desalination Reverse Osmosis Device by RO Process

Objective To study the operating parameters of the field seawater desalination reverse osmosis device by RO process and analyze quality of the product water.Methods In pressure of 4.90-6.37 MPa, the influence of operating pressure on salt rejection and water flux is researched to determine the best parameter. Except some conventional item test,the water quality analysis also includes BOD, COD, TOC, fluorescence spectra, ultraviolet spectra and chromatography of ions analysis. Results Operating pressure of 5.88-6.37 MPa, the water flux reaches 18-22 L/h and the ratio of desalinization exceeds 97.4%. The device has an organic contaminant elimination ratio higher than 95% and ion desalination ratio also more than 96%. The fundamental index is consistent with drinking water sanitary standard. Conclusion The field seawater desalination reverse osmosis device by RO process can effectively wipe off bacteria and contaminant of water and also can reduce salt salinity in untreated water to produce pure water for drinking.
