Abstract
For the reduction of boron concentration in SWRO (Sea Water Reverse Osmosis) permeate water, BWRO (Brackish Water Reverse Osmosis) is used as a post treatment In this study, the behavior of boron in this BWRO system and the effbct of operation parameters on the permeabi1ity of water, salt and boron are invesdgated using a test unit with 8-inch modules, The results are as follows: Firstly, the effect of concentration po1arization on module performance is not clear in the case of high flux with low feed rate.Secondly, the pH of pemleate water showed complicated behavior, Thirdly, the permeabilityof non-ionic boron isalmost constant in the pH range of 9 to 10.Finally, high recovery rado (95%) operation was possible with effective boron removal.
