Adding supports with inclusively immobilized, highly concentrated microorganisms to the biological reaction tanks results in a nitrogen treatment process that shortens reaction time. In the inclusive immobilization method, microorganisms in the agar state are enclosed in the supports, and this method is effective for slow-multiplying microorganisms (example: nitrifying bacteria that change ammonia to nitric acid).
