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

该项目将研究一种结合纳米浮选和超滤的先进水净化方法。大卫布罗姆利工程有限公司开发了一种被称为可更换皮肤层膜的技术。在这种方法中，粉末被迅速吸附到钢支撑膜上。该粉末将使纯净水通过支架，同时捕获金属离子。关键的创新之处在于，当粉末被污染时，可以迅速（几秒钟）去除并更换。该项目将基于已经存在的先导化合物开发固体“表皮”材料的结构活性关系。该技术适用于任何废水，工业或市政，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皮层，例如，不仅可以去除，还可以回收更多有价值的金属。该研究涵盖了基础化学和表面科学，以及在实际工业用水中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.
