Abstract

Indiscriminate wastewater discharges with high sulfate containing can affect water quality and aquatic ecosystems, requiring a previous treatment. An alternative treatment for this effluent is sulfate reducing reactors with microorganisms that oxidize organic compounds and use sulfate as electron acceptor, producing hydrogen sulfide. Most of the studies in literature focus on sulfate removal and not on hydrogen sulfide production. However, this gas have several applications like precipitate metals from acid mine drainage or production of elemental sulfur, which have high added value. This project aim to study and optimize the hydrogen sulfide production using upflow anaerobic packed bad bioreactor with open pore polyurethane foam as support material and glycerol as energy source. For this, we have an association with the "Reactores Biológicos y Enzimáticos" research group of University of Cádiz - Spain, one of the most experienced sulfide treatment groups in the world. (AU)
