Seawater desalination plants that use reverse osmosis (RO) membranes have become a core part of social infrastructure, and should be designed to meet the needs of product water quality and production capacity, while considering various environmental factors such as the seawater quality, temperature and geographical features. Furthermore, stable operation while overcoming various problems should be achieved alongside the increasing demands for energy saving and cost reduction. As no universal plant apparatus and operation technology meets these various requirements, the plants need to be customized for individual solutions. This paper reviews and summarizes the proven technologies, including their advantages/disadvantages, and points to cutting-edge technologies related to the design and operation maintenance of seawater intake, pre-treatment and the RO desalination process.
采用反渗透（RO）膜的海水淡化厂已成为社会基础设施的核心组成部分，其设计应满足产水水质和生产能力的需求，同时考虑海水水质、温度和地理特征等各种环境因素。此外，在满足日益增长的节能和成本降低需求的同时，还应克服各种问题实现稳定运行。由于没有通用的设备装置和运行技术能满足这些多样的要求，因此需要针对具体解决方案定制工厂。本文回顾并总结了已证实的技术，包括其优缺点，并指出了与海水取水、预处理和RO淡化工艺的设计及运行维护相关的前沿技术。
