Marine reverse osmosis desalination plant — a case study

In the present work, one type of reverse osmosis desalination plant with 2.5 t/d product was introduced. An experimental study was carried out, the result of experiment was analyzed. The calculation data using ROSA software developed by Dow Chemical company was given. By regression analysis of the experimental data, the model correlations were given. The conclusion is that with the increment of operation pressure, the power consumption increased linearly, the flow rate of product and percent recovery increased accordingly, the concentration of product decreased reversibly.
