Treatment of Boronated Waste Water using
an RO Membrane
+
In treatment of boronated waste water by using an RO membrane,
what are the most important factors that should be considered? How
does the pH factor influence the performance of the treatment (type
of membrane that have been used is spiral wound)? pH will influence
the concentration of the boron in the water. By theory, the treatment
should be done in the pH condition that the boron concentration is
minimized. When doing this filtration, what type of ion boron is the
easiest to reject (ion boric acid or the complex ion of boron)?
For your information, the concentration of boron is analyzed with
the HACH DR/2000 by Carmine method.
