WebCorn stover biochar (CSB) and maple biochar (MB) were added into anaerobic digesters and evaluated for hydrogen sulfide (H 2 S) reductions. This was the first study to show Fe-impregnated biochar can eliminate H 2 S production. The novel study evaluated biochar addition on H 2 S reduction and nutrient concentrations using three experiments to test … WebJan 12, 2024 · At the BARC Dairy Unit, six field-scale 3 m 3 (105 cubic feet) capacity horizontal plug flow anaerobic digesters have been constructed for research purposes. The digesters contain about 2 m 3 (75 cubic feet) of liquid and have about 1 m 3 (35 cubic feet) of headspace above the liquid. In July 2016, researchers began evaluating microaeration ...

Webthrough bacterial activity, hydrogen sulfide (H2S) is formed. Sulfide formation, which occurs when the ORP is between -50 to -250 mV, is a critical event in an anaerobic digester, where the sulfide serves as a sulfur nutrient for facultative anaerobic and anaerobic bacteria including the methane-producing bacteria.
