Enhancement of nitrate removal under limited organic carbon with hydrogen-driven autotrophic denitrification in low-cost electrode bio-electrochemical reactors

Nitrate-contaminated water is a concerning environmental and health problem in agricultural areas. Due to its low organic carbon content, such water cannot be purified using a conventional bioreactor with heterotrophic denitrification. Low-cost bio-electrochemical reactors were established with the aim of enhancing denitrification performance by cooperation of heterotrophic and hydrogenotrophic denitrification.
