Tenaska deploys GE advanced water treatment technology

US-based energy company Tenaska has deployed GE’s advanced water treatment technology to upgrade its 845MW combined-cycle power plant.

The natural gas fired plant is located near Mt. Enterprise in Rusk County, Texas, and is owned by Tenaska Gateway Partners.

Tenaska said GE technology has reduced operational costs and the number of water treatment agents required at the Tenaska Gateway Generating Station.

Tenaska Gateway Generating Station plant manager Steve Pearson said the power plant was first commissioned using GE’s gas turbine and steam generator technology and has now been upgraded using the advanced water purification technology.

"GE’s new water treatment equipment enables us to use water more efficiently," said Steve Pearson.

Tenaska upgraded its main water purifier, which uses existing ion exchange technologies, with GE’s equipment utilising reverse osmosis membrane technology.

In addition, GE technology can treat the plant’s water used in the heat recovery steam generators and cooling tower.

Enhanced with the advanced water technology, the power plant now uses fewer water treatment agents, preventing degradation of water quality and reducing the need for additional treatment.

The technology does not need to regenerate the demineralisers frequently and saves money and reduces the amount of treated wastewater returned to the environment.

GE Power & Water water and process technologies engineered systems general manager Yuvbir Singh said advanced water treatment technology allows the Tenaska Gateway Generating Station to use water resources in a responsible way and save money on operation.

"Tenaska and GE both continue to be committed to safe, reliable and environmentally responsible operations. This site’s commitment to those principles causes it to be nominated and earn the GE Return on Environment Award," added Singh.
