Boron removal by reverse osmosis membranes in seawater desalination applications

A comparative evaluation of reverse osmosis membrane performance when combined with anaerobic or aerobic membrane bioreactors for indirect potable reuse applications

“…Low Boron (B) removal was found in both permeates with 62 % and 48 % removal for the AnMBR-ROP and AeMBR-ROP, respectively. This finding agrees with Tu et al [58] that the Boron rejection rate increases with increasing pH and operating pressure but decreases when temperature and fouling increase. In this study the less preferable feed water pH and operating pressure led to the low boron removal.…”

Enhanced boron rejection by NF/RO membranes by complexation with polyols: Measurement and mechanisms

“…The changes in boron rejection as a function of pH reported here are consistent with previous studies in the literature (e.g. [7,13]). …”

Boric Acid Permeation in Forward Osmosis Membrane Processes: Modeling, Experiments, and Implications

“…It is worth noting that based on current FO membrane technology, the AL-DS orientation is not preferred due to its higher fouling potential and lower removal efficiency of contaminants. Finally, previous studies reported that boron rejection by RO membranes was influenced by pH, temperature, and membrane fouling . The effect of these parameters on boron rejection by FO membranes will be investigated in our further studies.…”
