Capstone Turbine Corporation, a leading clean technology manufacturer of microturbine energy systems, has received an order for three C800 microturbine systems for a large wastewater treatment plant in Brazil.

The total order value is in excess of US$2 million and is the first sale of Capstone C800 microturbines in South America.

Fluxo Servicios de Petroleo, Capstone’s distributor in Brazil, ordered the three C800 microturbines for a wastewater treatment plant that serves two cities. The microturbines will run on methane created during the treatment process.

The plant, which treats 4,500 liters of sewage per second, will use the ultra low-emission microturbines in a combined heat and power (CHP) application.

In addition to producing 2.4 MW of electricity to power the plant’s equipment and buildings, the excess heat produced by the methane-fueled microturbines will help maintain the proper temperature in the plant’s on-site digester used to breakdown the sewage.

“Wastewater treatment in Brazil is a key issue in the country’s efforts to continuously improve water quality,” said Hideo Hama, president of Fluxo Servicios de Petroleo.

“In addition, Brazil is working to diversify its energy supplies beyond hydroelectric and increase electrical efficiency. That’s where renewable energy sources such as biogas fueled Capstone microturbines can play a key role in helping meet these renewable energy needs,” he added.
