Abstract:
The use of humidification-dehumidification water desalination technology has been shown to be a practical means of meeting the demand for freshwater. The aim of this review is to investigate the impact of salinity on HDH techniques that have various benefits in terms of both economics and the environment, including the capacity to operate at low temperatures, utilize sustainable energy sources, the need for low maintenance, and straightforward construction requirements. Also, in this review, it is observed that the HDH system\'s components are strong and capable of treating severely salinized water. It can treat water in an appropriate way than other desalination technologies. This technology has recently been commercialized to treat highly salinized generated water. However, more research is needed to determine how salinity affects HDH productivity. According to several research investigations, while the specific thermal energy consumption increased considerably and the productivity of water per unit of time decreased significantly as the salt mass percentage grew, the purity of clean water did not suffer. The rejected brine must be reduced by increasing the total water recovery ratio in the HDH system. Through this review, it was found that brine control is becoming increasingly important in the water processing industry. ZLD systems, which aim to recover both freshwater and solid salts, can be a viable replacement for disposal methods. Finally, through this reviewer, it was concluded that HDH desalination systems may operate with extremely saline water while increasing salinity has a significant influence on system performance.
摘要:
使用加湿-除湿水淡化技术已被证明是满足淡水需求的实用手段。这篇综述的目的是调查盐度对HDH技术的影响,这些技术在经济和环境方面都有各种好处,包括在低温下工作的能力,利用可持续能源,需要低维护,和简单的施工要求。此外,在这次审查中,据观察,HDH系统的组件是强大的,能够处理严重的盐碱化水。与其他脱盐技术相比,它可以以适当的方式处理水。该技术最近已经商业化以处理高度盐化的生成水。然而,需要更多的研究来确定盐度如何影响HDH生产率。根据一些研究调查,随着盐质量百分比的增加,比热能耗大幅增加,单位时间的水生产率显著下降,清洁水的纯度没有受到影响。必须通过增加HDH系统中的总水回收率来减少排出的盐水。通过这次审查,发现盐水控制在水处理行业中变得越来越重要。ZLD系统,旨在回收淡水和固体盐,可以是处置方法的可行替代品。最后,通过这个审稿人,结论是HDH脱盐系统可能在极盐水下运行,而增加盐度对系统性能有重大影响。
