9-43: Immobilization of Nitrifier for Nitrogen Removal

The immobilization of biocatalysts (cells or enzyme) and its application have recently been the subjected of increased interest, which may be defined as the physical confinement or localization of intact cells to a certain defined region of space with the preservation of some desired catalytic activity. Biocatalysts immobilization techniques offer a promising potential for the improvement of the efficiency of bioprocess, the production of useful metabolites and biological wastewater treatment. The immobilization of biocatalysts has also attracted attention due to several advantages, including the easy separation of liquid and solid in a setting tank, a high loading biocatalysts content, the preservation of biocatalysts from the external environment and the prevent of wash-out. Many immobilization methods have been suggested for applications to microorganisms. Several natural materials and synthetic polymeric matrices have been used for cell immobilization. In this study, The objective of this experiment are to immobilize nitrification microorganisms to several support materials and to measure nitrification rate of immobilized carriers.
