Abstract：

Experiments of removing boron using SWRO membrane were carried out on a pilot equipment. Results show that boron rejection performance of test SWRO surpass BWRO & FILMTEC SWRO. Boron rejection at natural pH is 60%～80% and can reach above 98% by adjusting pH. When feed water pH≤8.0 boron rejection evidently raises following pressure increasing and the influence diminishes at pH≥9.5. In addition, boron rejection of SWRO is independent on recovery ratio and feed boron concentration. So improving feed water pressure and pH can effectively promote the boron removing performance of RO membrane.
