摘要 闭路海水淡化 (CCD™) 技术是反渗透 (RO) 水处理和海水淡化的新兴平台。它降低了进水压力要求，提高了膜性能，增加了操作灵活性，并且无需仅使用标准反渗透设备的能量回收装置。对于工业水处理和苦咸水淡化应用，CCD 技术可在单级装置中实现最大回收率，同时节省能源。或者，可以在传统 RO 工艺中添加 CCD 装置，以浓缩盐水并提高回收率。单阶段操作已证明回收率超过 97%。 CCD装置的回收率可以在控制面板上调节，无需修改系统硬件，仅受给水结垢特性的限制。最大回收率操作和高度灵活性对于工业水处理和内陆苦咸水淡化具有显着的成本削减影响，这两者都...
Abstract Closed Circuit Desalination (CCD™) technology is an emerging platform for reverse osmosis (RO) water treatment and desalination. It lowers the feed pressure requirement, improves the membrane performance, increases the operational flexibility, and eliminates the need for energy recovery devices using only standard RO equipment. For industrial water treatment and brackish water desalination applications, CCD technology achieves maximum recovery in single-stage units while saving energy. Alternately, a CCD unit can be added to a conventional RO process to concentrate brine and raise recovery. Over 97% recovery has been demonstrated in a single-stage operation. The recovery rate of a CCD unit can be adjusted at the control panel without modification of system hardware, limited only by the scaling characteristics of the feedwater. Maximum recovery operation and high flexibility have significant cost-cutting implications for industrial water treatment and inland brackish desalination, where both feedw...
