A new approach to improve efficiency of reverse osmosis systems by adding a low salt rejection stage, which can be retrofitted into existing water treatment configurations, is investigated by creating simulation in Wolfram Mathematica with a user-friendly UI.
The creation of this software is warranted as currently no other free alternatives exist which can simulate these complex systems with high accuracy.
Firstly, to ensure that the mathematical model in the presented software is accurate enough, it’s compared against commercial reverse osmosis simulation software for validation, for which it shows agreement on average of 97%.
Then the program is used to optimize the low salt rejection system, for which the second stage’s parameters are optimized, decreasing specific energy consumption by up to 2.8% for sea water reverse osmosis. It is proposed that further research be focused on brackish water treatment, which shows much better prospects.
