The proposed research aims to develop innovations in membrane technologies and accelerate those innovations to the pilot-scale for industrial applicability. The project is divided into three components: 1. Electrically conductive membranes to prevent surface fouling 2. Recycling fouled membranes for non-potable reuse applications and 3. Material scale-up and pilot-scale testing of both. In part 1, the focus is on operating conditions of electrically conductive anti-fouling membranes. We will evaluate the anti-colloidal and anti-biofouling capabilities of electrically conductive MF and UF membranes, synthesized from several established techniques in the de Lannoy lab. We will further investigate how operating conditions (applied voltage strength, polarity, frequency) impact the anti-fouling abilities of electrically conductive membranes and develop models to predict the optimal operating conditions. In part 2, the focus is on membrane material modifications. Fouled membranes will be recycled and reused by etching old/used microfiltration (MF), ultrafiltration (UF), and reverse osmosis (RO) membrane surfaces. These fouled, etched and recycled membranes will be used to separate municipal wastewaters. The permeate will be treated with UV disinfection and the product water will be evaluated for viability in non-potable reuse applications. In part 3 of the proposed research we will focus on investigating scaling-up of electrically conductive and recycled membranes. We will establish methods to scale up electrically conductive membranes for applications in Pall's membrane production line. Scale-up production includes co-extrusion coating techniques to coat MF and UF membranes with electrically conductive surface layers. We will also recycle fouled membrane modules and use them in the pilot scale systems currently at the Greenway wastewater treatment plant operated by Trojan. We will couple the effluent from the recycled membrane modules to inline UV disinfection and assess the water quality for its applicability to non-potable reuse applications.

拟议的研究旨在开发膜技术的创新，并将这些创新加速到飞行员规模的工业适用性。该项目分为三个组成部分：1。导电膜以防止表面污染2。用于无可重复使用应用的回收污染膜和3。两者的材料缩放和试验尺度测试。在第1部分中，重点是导电抗污染膜的工作条件。我们将评估从De Lannoy Lab中的几种已建立技术合成的导电MF和UF膜的抗胶体和抗双重能力。我们将进一步研究工作条件（应用电压强度，极性，频率）如何影响电导膜的抗死能力，并开发模型以预测最佳的工作条件。在第2部分中，重点是膜材料修饰。污染膜将通过蚀刻旧/二手过滤（MF），超滤（UF）和反渗透（RO）膜表面来回收和重复使用。这些犯规，蚀刻和回收的膜将用于分离市政废水。渗透性将用紫外线消毒处理，并将评估产品水以在非替代重用应用中的生存能力。在拟议的研究的第3部分中，我们将重点介绍缩放导电和回收膜的扩大。我们将建立用于扩展PALL膜生产线中应用的导电膜的方法。扩展生产包括与电导性表面层涂层MF和UF膜的共排除涂料技术。我们还将回收污染的膜模块，并将其用于特洛伊木马经营的Greenway废水处理厂的试验量表系统。我们将将从回收的膜模块的废水融入内联紫外线消毒，并评估其适用于非可重复使用应用的水质。
