Following the shutdown of groundwater wells, Zhengding Power Plant in China shifted its water source from groundwater to surface water, leading to increased water withdrawal costs. To optimize operations and reduce electricity generation costs, the plant launched an innovation program focused on reducing water consumption and recovering waste heat. This process involved internal workshops, water quality analysis, and project planning. As a result, the plant constructed the water recovery pipelines and installed pumps at the chemical plant and cooling tower to recirculate and reuse blowdown water within the operational process.
