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

该项目将介绍一种先进的纳浮和超滤相结合的净水方法。David Bromley Engineering Ltd.开发了一种名为可更换皮肤层膜的技术。在这种技术中，粉末被快速吸附到钢支撑膜上。这种粉末将使纯净水在捕获金属离子的同时通过支架。关键的创新是粉末在被污染时被快速(秒)移除和更换的能力。该项目将在已经存在的铅化合物的基础上，开发固体“皮肤”材料的结构活性关系。这项技术在任何工业或市政废水中都有应用，但首先将对油砂开发的尾矿水进行测试。第一个关键指标是纯净水，但从这个项目中获得的知识可以用于开发金属选择性皮肤层，例如，不仅可以去除更有价值的金属，还可以回收更有价值的金属。这项研究涵盖了基础化学和表面科学，以及使用真正的工业用水进行的小规模原型工程测试。培训经验是多学科的，对公司和加拿大乃至全球的自然资源行业具有广泛的价值。

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.
