MUMBAI, India, Aug. 8 -- Intellectual Property India has published a patent application (202411004792 A) filed by Council Of Scientific And Industrial Research, New Delhi, on Jan. 23, 2024, for 'an upflow anaerobic granular bed microbial electrochemical reactor [uagb-mer] for production of bio-h2 from liquid waste/wastewater.'
Inventor(s) include Kundu Partha; and Sivaraman Savithri.
The application for the patent was published on Aug. 8, under issue no. 32/2025.
According to the abstract released by the Intellectual Property India: "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."
