Due to advances in desalination technology, desalination has been considered as a practical method to meet the increasing global fresh water demand. This paper explores the status of the desalination industry and research work in South Korea. Desalination plant designs, statistics, and the roadmap for desalination research were analyzed. To reduce energy consumption in desalination, seawater reverse osmosis (SWRO) has been intensively investigated. Recently, alternative desalination technologies, including forward osmosis, pressure-retarded osmosis, membrane distillation, capacitive deionization, renewable-energy-powered desalination, and desalination batteries have also been actively studied. Related major consortium-based desalination research projects and their pilot plants suggest insights into lowering the energy consumption of desalination and mitigation of the environmental impact of SWRO brine as well. Finally, considerations concerning further development are suggested based on the current status of desalination technology in South Korea.
由于海水淡化技术的进步，海水淡化已被视为满足全球日益增长的淡水需求的一种切实可行的方法。本文探讨了韩国海水淡化行业的现状和研究工作。分析了海水淡化厂的设计、统计数据以及海水淡化研究路线图。为降低海水淡化过程中的能源消耗，人们对海水反渗透（SWRO）进行了深入研究。最近，包括正向渗透、压力延迟渗透、膜蒸馏、电容去离子、可再生能源驱动的海水淡化以及海水淡化电池在内的替代海水淡化技术也得到了积极研究。相关的基于大型财团的海水淡化研究项目及其试验工厂为降低海水淡化能耗以及减轻SWRO浓盐水对环境的影响提供了思路。最后，根据韩国海水淡化技术的现状，提出了关于进一步发展的考虑因素。
