The development of advanced treatment technology for reclaimed water reuse, their application status in thermal power generation plants in China, and the limitations and controlling strategies for these technologies are reviewed. Lime coagulation was the 2nd generation reclaimed water treatment technology, which has been widely applied. Membrane technology becomes the mainstream technology for reclaimed wastewater reuse due to its excellent performance. Membrane fouling is the limiting factor for membrane processes, therefore the membrane fouling issue and its control strategies are becoming the research focus. With the development of water treatment technology and equipment, new-type advanced treatment processes as well as new technologies, materials have been applied in the reclaimed water treatment. The reclaimed water would be the first option for thermal power generation plants in the future, and dual-membrane technology will be the key advanced treatment technology, with the pretreatment and advanced treatment technologies developed efficiently.
