With a total of 2 patents, his work focuses on enhancing the efficiency and effectiveness of anaerobic treatment methods.

Latest Patents

Honma's latest patents include a "Process and apparatus for anaerobic treatment of sulfur compound-containing wastewater." This invention aims to provide a high-performance upflow anaerobic sludge treatment targeting organic wastewater that contains inorganic sulfur compounds. The process involves detecting hydrogen sulfide concentrations in biogas generated during methane fermentation treatment. If the concentration exceeds a predetermined value, a desulfurization treatment operation is initiated. The preferred concentration range for hydrogen sulfide is between 1% to 2%.

Another significant patent is the "Method and apparatus for the methane fermentation treatment of wastewater containing sulfur compound." This method involves adding an oxidizing agent to the organic wastewater to oxidize sulfur compounds before the anaerobic treatment step. The oxidizing agent can be ozone, hydrogen peroxide, sodium hypochlorite, or a bromine-based oxidizing agent. The concentration of hydrogen sulfide in the biogas is monitored to control the amount of oxidizing agent added, ensuring it remains at 3% or less.
