Sludge treatment solutions in sewage sector

High-speed methane fermentation


This system generates bio-gas by carrying out methane fermentation of sludge from a wastewater treatment plant or food wastes.

The bio-gas is comprised approx. 60% of methane and approx. 40% of CO2. The gas can be used for power generation and heating. Further, the amount of sludge can be drastically reduced by carrying out methane fermentation.


METAWATER preserves a high concentration of methane bacteria by filling a carrier in the fermentation tank and this makes high-speed fermentation possible.

Further, based on a unique control technology, high-speed fermentation is achieved simultaneously with stable operation so as to develop a compact and low-cost methane fermentation system.
