Boron Rejection by Reverse Osmosis Membranes – National Reconnaissance and Mechanism Study
Introduction
The mechanism of boron rejection by reverse osmosis membrane and transport was studied by bench experiments using six commercial reverse osmosis membranes.
A mathematical model was developed to predict boron rejection by reverse osmosis membranes under different operating conditions such as pressure, pH, and temperature.
Boron concentrations in feed and product water from nine pilot or full-scale plants were analyzed in parallel.
Comparison with bench-scale data suggested that the level is much lower than the boron rejection observed in the field data, mainly due to the high target recovery rate.
