Borate (Boron)
Source of Borate (Boron)
Borate B (OH
4) is a compound of Boron. Most of the world's boron is contained in seawater. Sodium borate occurs in arid regions where inland seas once existed but have long since evaporated. Boron is frequently present in fresh water supplies in these same areas in the form of non-ionized boric acid. The amount of boric acid is not limited by drinking water standards, but it can be damaging to citrus crops if it is present in irrigation water and becomes concentrated in the soil.
Treatment of Borate (Boron)
Boron behaves like silica when it is in an aqueous solution. It can be removed with an Anion Exchanger or adsorbed utilizing an Activated Carbon Filter.
