| The facility for collecting, refining and
storing the sludge digestion gas. Methane gas generates from anaerobically fermented sewage sludge. This is what we call the digestion gas. It does have sufficient safeness and can be operated easily, even for the toxic and corrosive sulfurized hydrogen. |
