In view of the difficulty in treating the bioleaching solutions, the selective precipitation of metals using H2S produced biologically by sulfate reducing bacteria (SRB) was put forward. In this paper, two anaerobic fixed bed bioreactors fabricated from Plexiglas was used to produce hydrogen sulfide by continuous operation, porcelain rings and synthetic sponge (polyurethane foam) were used as immobilization...
Anaerobic hydrogen fermentation converting carbohydrate-rich wastewater to clean hydrogen energy is a renewable technology for hydrogen production. Applying immobilization technology on biohydrogen production could make the biohydrogen producing system durable and stable in response to organic load impacting and low pH value. This study investigated granular activated carbon to immobilize hydrogen...
