Technology of safe disposal of metallic mercury in industrial sewage by a biological method

Environmental contamination with heavy metals, such as mercury, poses a serious ecological problem. The Department of Bioprocess Engineering offers the technology of bioreduction based on the use of microorganisms.

Out of the three forms of mercury (metallic, ionic and organic) present in industrial sewage, mainly in the chemical industry, the ionic mercury (i.e. as soluble salts) prevails. Instead of a chemical reaction with a strong
reducing agent, the mercury salts can be reduced biologically by means of live bacteria with such abilities. Appropriate bacterial strains were isolated from the environment of natural river deposits.

This technology is dedicated to enterprises from the chemical branch and to sewage treatment plants.
