反渗透（RO）海水淡化系统具有许多优点，例如节省能源和使用较少的安装空间，并且已经成为从海水中获得淡水的常规技术。降低能源和安装空间的一个重要方法是提高系统回收率，我们开发了一种新的RO海水淡化系统，该系统可将3.5%的海水回收60%的淡水。这项新技术被称为盐水转换两级SWRO系统（BCS）。该系统包括系统结构、能量回收、运行工况等多项新技术;高性能膜技术、抗生物污染技术和新的分析方法。自1997年以来，东丽爱媛工厂的试验工厂已成功运营。自1999年3月以来，第一个4500 m3/d（1.2 mgd）的商业工厂已在Mas Palomas（Gran Canaria，西班牙）成功运行。加勒比地区的托尔托拉和库拉考工厂已安装完整的BCS（一级+二级RO系统），并且也在良好的条件下运行。安装在日本室户工厂的BCS新应用已经投入运行，用于从深海中获取瓶装饮用水和高浓度矿化水。此外，西班牙和加勒比地区的其他工厂正在建设中。BCS被认为是21世纪世纪的标准SWRO系统。
A reverse osmosis (RO) seawater desalination system has many advantages such as saving energy and using less installation space, and has become regular technology to obtain fresh water from seawater. A significant way to lower energy and installation space is to raise system recovery, and we have developed a new RO seawater desalination system which provides 60% recovery of fresh water for 3.5% seawater. The new technology is called a brine conversion two-stage SWRO system (BCS). This system includes several new technologies such as system configuration, energy recovery, operating condition, etc.; high-performance membrane technology; anti-biofouling technology and a new analysis method. A pilot plant has been operated successfully at Toray's Ehime plant site since 1997. The first commercial plant of 4500m3/d (1.2 mgd) has been operating successfully since March 1999 in Mas Palomas (Gran Canaria, Spain). The Tortola and Curacao plants in the Caribbean have been installed with the full BCS (first-+second-stage RO system), and also operated under good conditions. A new application of the BCS, installed at the Muroto plant in Japan, has been in operation to obtain bottled drinking water and high concentrated mineralized water from deep seawater. Furthermore, other plants are under construction in Spain and the Caribbean. The BCS is presumed to be the standard SWRO system for the 21st century.
