Abstract
The European Union (EU) stipulates the maximum admissible value for the con centration of boron at 1 ppm and the World Health Organization (WHO) at 0.3 ppm as the non-observed effect level (NOEL) for drinking water. The conten t of boron in water can be reduced by means of various processes. Treatment by means of conventional reverse osmosis only reduces the boron content by 60%. This paper analyzes the possibility of treating the permeate water in a way that increases the pH.
