Our advanced 2G® SE-TEC® energy generation technology utilizes biogas from the fermentation and incineration process (anaerobic digestion) of sewage sludge at WWTP’s to generate electricity and heat using a fuel that is both efficient, and providing many economic benefits. 2G® SE-TEC® cogeneration modules are specifically developed for WWTP biogas applications. A compact CHP design with integrated control-and switchgear, thermal energy distribution system and advanced enclosure options.

Biogas produced from sewage sludge is a source of energy with no net carbon emissions, and it has an important role to play in the reduction of greenhouse gases. The anaerobic digestion of sewage sludge involves fermenting it in tanks at a temperature between 32 and 36 degrees centigrade. The temperature in the digestion tank is kept constant using heat energy generated by a the combined heat & power plant.

The biogas produced is then compressed before being transformed into energy. Minimal gas treatment is required to operate our CHP units that are specifically designed and built for corrosive gas types. The resulting quantities of heat and electricity are utilized to operate the waste water sewage facility. Excess electrical energy can be fed into the public electricity grid. Surplus thermal energy is generally utilized to heat nearby buildings, green houses, commercial facilities, homes, as well as being used in agricultural or industrial processes.

The constant flow of feedstock to WWTP's is steady and consequently the cogeneration plant provides a continuous 24/7 electrical base-load. In addition to being environmentally sound, this type of energy generation provides water treatment plant operators and water authority operations with long-term economic benefits.

2G® is a trusted equipment provider for many WWTP’s all over the world. Biogas plants are only as good and reliable as the overall design, and the quality of the CHP cogeneration module converting biogas into valuable electric and thermal energy. We realize that anybody can claim to use only highest quality components, promising reliable and efficient systems. The difference can be found in the details. Innovative technologies combined with unmatched experience result in incomparable CHP solutions and longevity.

In late 2009 our factory reached a milestone of 1200 CHP cogeneration systems manufactured, supplied and installed. Thanks to an additional production plant opened in 2009 and a new factory extension to be operational in Oct. 2010, the total number of installed CHP systems is expected to reach 1800 by the end of 2010.

When it comes to WWTP biogas power generation our customers don’t take chances. Time after time the worlds leading biogas plant developers select 2G® to safeguard their investment and success. Why? Because there is no higher level of quality, efficiency, and durability available. We could offer you promising words,… but the numbers of installed units say it all.

2G® sewage gas CHP cogeneration plants are excellently qualified for easy and space saving installation. The compact design with integrated control-and switchgear provides many advantages. 2G® enjoys the highest level of expertise and years of experience, providing customers with attractive advantages and value-added solutions in climate protection and technologies for electricity and heat generation.
