BIOREMEDIATION OF DIFFERENT WASTE WATERS – A REVIEW

Bioremediation of different waste waters is a relatively new technology that has undergone more intense investigation in recent decades. As rapid industrialisation and urbanisation releases numerous toxic compounds into natural water bodies, polluting both fresh water resources as well as marine water. This process is focused on destroying or immobilizing toxic waste materials present in these water sources. Several techniques have been proposed for efficient wastewater treatment, most of them presenting some limitations, such as poor capacity, the generation of waste products, incomplete mineralisation and a high operating cost.The bioremediation of waste waters can be divided into two broad categories: In-situ and Ex-situ treatment. Both methods have significant advantages and disadvantages. The bioremediation process for different waste waters is discussed in this paper in brief.
