在日本的“百万吨水系统”项目中，开发了一种用于大型反渗透装置的新型反渗透系统。新开发的反渗透系统提高回收率的特点是第一级使用含有2-4个元件的短容器，在中间增压泵后的第二级采用较长的容器，以降低前置元件的压力和流量。本项目研究的低压新型反渗透元件所采用的新型反渗透系统具有较高的回收率（低于65%），并允许与传统系统相比，减少进气和预处理设备的规模。同时考虑到本项目开发的新型等压ERD，对该系统的能耗进行了估算，并与常规系统的能耗进行了比较。建议与传统系统相比，能耗降低约20%。(C)2015爱思唯尔B. V.保留所有权利。
A new RO system for large-scaled SWRO plant has been developed in the project named "Mega-ton Water System" with private-public cooperation in Japan. The characteristic of the newly developed RO system to increase the recovery rate is to use the short vessel that contains 2-4 elements for the first stage, and to use relatively long vessel for the second stage after inter-booster pump in order to reduce the pressure and the flux of the lead element The new RO system used by low pressure new SWRO element studied by this project is capable of the high recovery rate (under 65%) and allows the scale of the intake and pretreatment equipment to reduce compared to conventional system. Considering also to new isobaric ERD that has been developed in this project, the energy consumption was estimated and compared the results with that of conventional system. It is suggested that the reduction of energy consumption is to be about 20% compared with a conventional system. (C) 2015 Elsevier B.V. All rights reserved.
