He has made significant contributions to the field of wastewater treatment, particularly focusing on processes that involve sulfur compounds. With a total of 2 patents, his work is recognized for its innovative approaches to environmental sustainability.

Latest Patents

Kamachi'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%, and the treatment involves adding a desulfurizing agent containing iron ions.

Another significant patent is the "Method and apparatus for the methane fermentation treatment of wastewater containing sulfur compound." This method includes 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 serves as an indicator for controlling the amount of oxidizing agent added.
