Polymeric nanofiltration membranes are used for organics removal from raw water during drinking water production. A highly selective separation is fostered by accommodating a strict pore size which can also improve continuity in downstream asset operation (e.g. disinfection), therefore enhancing resilience of drinking water supply. However, current polymeric membranes exhibit several challenges. Ceramic nanofiltration (C-NF) is an emerging technology that introduces a thin separation layer to foster selectivity without significant loss to permeability. Several advantages are proposed. While these unique properties can foster a radical shift in the economics, operability and resilience of nanofiltration, C-NF has yet to be developed explicitly for drinking water treatment, where these separation attributes must be challenged to evidence their translatability to this industrial context. This project therefore seeks to evaluate C-NF as a next generation technology for the production of drinking water from organic rich raw waters.

在饮用水生产过程中，高分子纳滤膜用于去除原水中的有机物。通过适应严格的孔径，可以促进高度选择性分离，这也可以提高下游资产操作（例如消毒）的连续性，从而增强饮用水供应的弹性。然而，目前的聚合物膜表现出一些挑战。陶瓷纳滤（C-NF）是一种新兴的技术，它引入了一个薄的分离层，以促进选择性，而不会显著损失渗透性。提出了几个优点。虽然这些独特的特性可以促进纳滤的经济性，可操作性和弹性的根本转变，但C-NF尚未明确开发用于饮用水处理，其中这些分离属性必须受到挑战，以证明其可翻译到这种工业环境。因此，本项目旨在评估C-NF作为从富含有机的原水中生产饮用水的下一代技术。
