随着水的稀缺性增加，向循环经济的发展和ESG推动更好的环境绩效，高速水回收工艺变得越来越重要。例如，资源行业正面临着越来越大的压力，需要改善环境性能以满足ESG的责任，这通常意味着减少与水排放有关的环境影响。高回收率的工艺能够减少排放的洁净水中含有的污染物数量。减少的污染物量更容易管理。同样，在干旱时期，水的价值显著增加，尽可能多地回收清洁水成为一个目标。将讨论膜在高回收水处理过程中的作用，以及实现高水回收的方法和出现的挑战。将考虑二氧化硅作为限制水回收的污染物，并讨论减轻二氧化硅污损的方法。

High rate water recovery processes are becoming increasingly important as water scarcity increases, the move to a circular economy advances and ESG drives better environmental performance. The resource industry for example, is under increasing pressure to improve environmental performance to meet ESG responsibilities and this often translates reducing environmental impact associated with water discharges. High recovery processes are able to reduce the volume of contaminant laden streams from cleaned water that is discharged. The reduced contaminant volumes are then more easily managed. Similarly, during periods of drought the value of water increases significantly, and recovering as much clean water as possible becomes a target. The role of membranes in high recovery water treatment processes will be discussed along with approaches to achieving high water recovery and the challenges that arise. Silica as a contaminant that limits water recovery will be considered and approaches to mitigating silica fouling will be discussed.
