The presence of boron compounds in waters increases in a continuous and parellel way to
industrial development. Therefore, their harmful effects an living organisms also increases, especially
on plants, since this element manifests an important micronutrient-toxic boron duality. Boron is
widely distributed in the environment, mainly in the form of boric asid or borate salts. Generally
speaking, this element is an important micronutrient for living organisms, but the range between
deficiency and excess is narrow. For this reason, the World Health Organization (WHO)
recommendsin ist Guidelines for Drinking-Water Quality, a maximum boron concentration of 0.3
mgL-1. The same norms are recommended when seawater is used as a source of water. The aim of this
study to investigate the influence of different operation variables within the precipitation process of
boron with magnesium hydroxide when boron stock solution is being treated. Operation variables are
precipitant amount, stirring speed, contact duration, pH, temperature.
