Advanced nanomaterials for low pressure membrane water treatment - A project sponsored by David Bromley Engineering

该项目将解决一个先进的水净化方法，结合纳米浮选和超滤。大卫布罗姆利工程有限公司开发了一种称为可更换表层膜的技术。在该技术中，粉末被快速吸附到钢支撑膜上。该粉末将使纯净水能够通过载体，同时捕获金属离子。关键的创新是粉末能够在结垢时快速（秒）移除和更换。该项目将基于已经存在的先导化合物开发固体“皮肤”材料的结构活性关系。该技术可应用于任何工业或市政废水，但首次测试将在油砂开发的尾矿水中进行。 第一个关键指标是纯净水，但从该项目中获得的知识可用于开发金属选择性表层，例如不仅可以去除，而且可以回收更有价值的金属。该研究涵盖了基础化学和表面科学，以及使用真实的工业用水对小规模原型进行的工程测试。培训经验是多学科的，对公司和加拿大及全球自然资源行业的价值是广泛的。

This project will address an advanced method of water purification that combines Nanoflotation and Ultrafiltration. A technology known as a Replaceable Skin Layer Membrane has been developed by David Bromley Engineering Ltd. In this, a powder is rapidly adsorbed onto a steel support membrane. The powder will enable purified water to pass through the support while capturing metal ions. The key innovation is the ability of the powder to be rapidly (seconds) removed and replaced when fouled. This project will develop a structure activity relationship for solid "skin" materials based on a lead compound already in place. The technology has applications in any waste water, industrial or municipal, but first tests will be carried out with tailings water from oilsands development. The first key metric is purified water but knowledge gained from this project could be used to develop metal selective skin layers, for example to not just remove but recover more valued metals. The research spans basic chemistry and surface science to engineering testing on a small scale prototype with real industrial water. The training experience is multidisciplinary and the value to the company and the natural resource industry in Canada and globally is broad.
