IPC Classification: C02F9/14, C02F1/461, C02F3/00, C02F3/10, C02F3/12, C02F3/28, C02F101/30, C02F101/38
Abstract:
In the present invention, an integrated bio-electrochemical reactor system (BEC) has been developed for the production of bio-hydrogen from wastewater  (domestic/municipal wastewater) and simultaneous treatment of wastewater respectively. The developed BEC system intrinsically couples the upflow anaerobic  granular bed (UAGB) with microbial-electrochemical reactor (MER) together into an advance bio-reactor which employs biocatalyst to convert chemical energy stored  in organics to electrical energy. Hence, the developed novel UAGB-MER technology aims towards the enhancement of the metabolic activity of electrochemically  active biocatalyst by supplying organic/inorganic nutrients, electron acceptors, or donors, thus stimulating oxidation or reduction of contaminants for simultaneous  remediation of water and clean bio-Hydrogen (green H2) production. The present invention also relates to a process for treatment of organic enriched wastewater to  significantly reduce high concentrations of BOD (biochemical oxygen demand) and COD (chemical oxygen demand) from effluent stream.
Startup Options: Advantages of the developed novel UAGB-MER technology are:
  • Production of bio-hydrogen from wastewater  (domestic/municipal wastewater) and simultaneous treatment of wastewater. 
  • Intrinsically couples the upflow anaerobic  granular bed (UAGB) with the microbial-electrochemical reactor (MER) together 
  • A bioreactor employs a biocatalyst to convert chemical energy stored in organics to electrical energy. 
  •  Simultaneous remediation of water and clean bio-Hydrogen (green H2) production. 
  • Treatment of organic-enriched wastewater to significantly reduce high concentrations of BOD and COD from the effluent stream.
