Biogas is a green energy calling on more and more leading edge technical installations. Undoubtedly, the produced kW cost is not yet a competitor against nuclear or fossil fuel energies, but the systems installed are more and more efficient, and their financial profitability is increasing. In this field, Germany has built itself a world-leading position. Germany built 820 systems in 2006, increasing the total installed production units to 3700 and is now the No.1 world biogas base...
One of the more recent applications of membrane technology is in membrane bioreactors (MBR). The MBR design target is an ideal combination of bacteria to reduce the organic content of waste and membrane technology to remove particulate matter to produce high quality water for reuse.
