Boron concentration in produced water is significantly high. Produced water is water trapped in underground formation that is brought to surface along with oil and gas during drilling. Because this water has been in contact with the hydrocarbon formation for centuries, it now contains some of the characteristics of the formation as well as the hydrocarbons itself. Concisely, boron concentration in produced water makes produced water unusable if not properly removed. The World Health Organization (WHO) regulation guidelines for discharge of water into the environment set boron concentration at 0.5 mg L-1 for potable water. Many technologies have been developed to remove boron from produced water. However, there have been series of reported limitations based on the molecular weight of boron as well as its ionic dissociation constant. The health implication of boron consumption is enormous because according to the medico-biological investigations, boron compounds belong to the second class of the toxicological danger. The purpose of this study is to make an extensive review on published literatures on boron removal technologies in general, parameters that affect the efficiency of different treatment technologies, its importance, toxicity, deficiency and dissociation constant.
