The wastewater concentration and reduction project of Jiangsu Wuxi Ligang Power Plant is a demonstration project for the deep treatment of desulfurization wastewater in power plants. 

The desulfurization wastewater concentration and reduction project of Ligang Power Plant is the first desulfurization wastewater concentration and reduction project in China that uses carrier gas extraction technology. It can concentrate desulfurization wastewater to near saturation, with low pre-treatment requirements, and can fully utilize the waste heat of the power plant, achieving concentration and reduction of desulfurization wastewater at a lower cost. The project was put into operation in May 2018 and can efficiently treat desulfurization wastewater with various salt contents. It has good operational stability and cost advantages.
