The Study on the Removal of Odor Emitting Environmental Fundamental Facility

환경기초시설에서 발생하는 악취가스 제거에 관한 연구

The objective of the research project is to develop the hybrid deodorizer for the removal of residual harmful gases generating during pretreatment process of biogas. This hybrid deodorizer is capable of treating harmful gases that contains hydrogen sulfide ($H_2S$), ammonia ($NH_3$) and other odor substances. This hybrid deodorizer reduced the hydrogen sulfide content from approximately 150~200 ppm to less than 16 ppm. These residual harmful gases were effectively removed in the effluent, achieving up to 97% removal of $H_2S$ and 94% removal of $NH_3$ after treatment using hybrid deodorizer.
