This article shows the optimization of the reverse osmosis process in seawater desalination plants, taking the example of the Canary Islands, where there are more than 320 units of different sizes, both private and public. The objective is to improve the energy efficiency of the system in order to save on operation costs as well as reduce the carbon and ecological footprints. Reverse osmosis membranes with higher surface area have lower energy consumption, as well as energy recovery systems to recover the brine pressure and introduce it in the system. Accounting for the operation, maintenance and handling of the membranes is also important in energy savings, in order to improve the energy efficiency. The energy consumption depends on the permeate water quality required and the model of the reverse osmosis membrane installed in the seawater desalination plant, as it is shown in this study.
本文以加那利群岛为例，展示了海水淡化厂反渗透工艺的优化。加那利群岛有320多个不同规模的单位，包括私人和公共单位。目标是提高系统的能源效率，以节省运营成本，并减少碳足迹和生态足迹。具有较高表面积的反渗透膜能耗较低，还有能量回收系统来回收盐水压力并将其引入系统。考虑膜的运行、维护和处理对于节能也很重要，以提高能源效率。如本研究所示，能耗取决于所需的渗透水水质以及海水淡化厂中安装的反渗透膜型号。
