Abstract

Rising cases of environmental mercury hazards has led to a need for cost-effective mercury treatment techniques. Extensive use of mercury from ancient times has resulted in water contamination that may require remediation. Mercury contamination is tedious to treat and may pose a risk to human health and the environment. To deal with this threat of mercury contamination, industrial wastes and wastewaters containing mercury requires treatment for its removal and immobilization. This chapter provides a synopsis of the availability, performance, and technologies for management of mercury in water. It covers the innovative methods to treat the mercury contamination like biosorption. In this chapter, the technological aspects available for the mercury treatment technologies are reviewed. It describes the theory, design, and operation of the technologies; provides information on commercial availability and use; and includes data on performance, where available.

Sources Of Mercury

Mercury exists naturally in the environment and can be found in elemental (metallic), inorganic, and organic forms, mainly in the form of Methylmercury. Contemporary uses for mercury include chemical manufacturing, thermometers, and lighting (mercury vapor and fluorescent lamps) (Figure 1). All the chemical and allied products in the industrial group are responsible for the largest quantity of mercury used and produced (Beckers & Rinklebe, 2017).
