Pilot-Scale H2S and Swine Odor Removal System Using Commercially Available Biochar

Although biochars made in laboratory seem to remove H2S and odorous compounds effectively, very few studies are available for commercial biochars. This study evaluated the efficacy of a biochar (CBC) removing volatile organic (VOCs). We found that well-known Ergun equation may not be adequate predicting pressure drop properly sizing ventilation system. The breakthrough adsorption capacity CBC was 2.51 mg/g under humid conditions, which much higher than dry conditions. increased with influent concentration H2S. pilot-scale odor removal system (PSBORS) 15 VOCs by placing it swine gestation stall continually treating inside air 21 days. All PSBORS effluent were below detection limit except acetic acid. However, due high threshold acid, its contribution would minimal. It appeared could used reduce both potential recycling spent soil health improvement after using removal.
