GE to Provide Water Recycling Technology for Chinese Coal-Fired Power Plant

file

GE today announced it will supply advanced wastewater treatment equipment for the Jingneng Zhuozhou coal-fired power plant in Zhuozhou City, south of Beijing, China. GE will provide its membrane and brine concentration technologies followed by crystallization to produce pure sodium chloride salt.

China is facing long-term water scarcity and environmental challenges. The government recently tightened emissions and discharge limitations, requiring all new thermal power plants to achieve zero liquid discharge (ZLD) of flue gas desulfurization (FGD) wastewater as a condition of environmental impact assessment approvals.

ZLD technology will treat FGD wastewater to meet these emissions and discharge limitations, also enabling the reuse of 99 percent of the FGD blowdown wastewater at the plant. This wastewater will be recycled and used as makeup water.

The project is part of a plan to relocate high-pollution plants out of Beijing’s urban areas. The new Jingneng Zhuozhou Power Plant will replace the existing Shijingshan Power Plant, which was decommissioned in March 2015.

The new plant is expected to enter commercial operation in May 2017, and will serve as a demonstration ZLD power plant for the country.
