Since the beginning of water shortage by disasters such as global warming, environmental pollution, and drought, development of original technology and studies have been undertaken to increase the availability of water resources. Among the technologies, water treatment technology using membranes has a better water quality improvement than existing physicochemical and biological processes. Moreover, it is environmentalfriendly technology that does not use chemicals. Water treatment membranes are applied to various fields such as wastewater treatment, water purification, seawater desalination, ion exchange process, ultra-pure water production, and separation of organic solvents. Furthermore, water treatment technologies using membranes will increasingly expand. The core technology of the water treatment membrane is to control the size of pores for membrane performance and is being researched to improve performance. In this chapter, the frequencies of presentation are filed by country, institution, and company through technology competitiveness and evaluation of patents and papers. In addition, evaluation of technologies for wastewater treatment, water purification, seawater desalination, and ion exchange process was carried out in the same way as before. Finally, future research directions were suggested by using evaluation results.
