Boron is ubiquitous in seawater, at a concentration range of 4–6 mg/litre.
The World
Health Organization, the European Union, and
Health Canada have established health-based limits for boron in
drinking water, ranging from 1 to 2.4 mg/l.
According to the WHO
regulations, the boron concentration should be reduced to less than 0.5 mg/L for
drinking water.
It is also reported that, this limit is rarely reached for conventional
reverse osmosis desalination plants, equipped with commercially available membranes.
