Desalination of agricultural drainage return water. Part II: Analysis of the performance of a 13,000 GDP RO unit

Abstract The daily performance of a 49 ms3/d RO unit is reported in terms of the water and TDS transport parameters A and B, respectively. The rejections of the ions Na+, SO2-4, Cl− and NO−3, and alkalinity, boron and selenium are also reported for the begining and end of the testing period. The single stage RO unit consisted of six spiral-wound membrane elements (Model 4040-MSY- CAB3 manupactured by Hydranautics) placed in series.
