GE Jenbacher Engines To Be Used In Chili Wastewater Plant Expansion

Posted on December 3, 2010

Chilean water utility Aguas Andinas will install GE’s Jenbacher biogas engines as part of a wastewater treatment plant expansion and renewable energy project along the Mapocho River, near the capital city of Santiago, Chile.

Three of GE’s 2.7 MW J620 biogas engines will be installed to enable the plant to also begin producing up to 60% of its own power with renewable electricity. The engines will be fueled by methane-rich biogas created by the digestion of sewage sludge collected at the treatment plant.

The project is part of Chile’s efforts to clean up the city’s municipal water supply and protect the region from the environmental impacts of continued population growth, GE said.

The Mapocho expansion project is being built adjacent to the utility's existing “El Trebal” treatment facility and will enable Aguas Andinas to treat 100% of the Santiago region’s wastewater, up from its current capacity of 86%. The expansion, including a modernization of the El Trebal facility, is expected to be finished between late 2011 and the first quarter of 2012.
