Ozone-Enhanced Particle Removal in Water Treatment

结合臭氧化/生物活性炭过滤提供有效的污染物去除，同时最大限度地减少消毒副产物的形成。然而，常规水处理厂的安装成本非常高。本项目将研究臭氧化对小颗粒微絮凝的有益影响，旨在优化过滤前沉淀去除颗粒的效果。要做到这一点，需要清楚地了解溶解臭氧如何与不同水化学物质的颗粒表面相互作用。理想的结果将是开发一个强大的水处理系统，只需要BAC过滤，而不需要传统的砂过滤阶段。

Combined ozonation/biologically active carbon filtration provides effective contaminant removal while minimizing disinfection by-product formation. However, the cost of installation in conventional water treatment plants is very high. This project will investigate the beneficial influence of ozonation on the micro-flocculation of small particles, with the aim to optimising particle removal by sedimentation prior to filtration. To do this, requires a clear understanding of how dissolved ozone interacts with particle surfaces for different water chemistries. The ideal outcome would be to develop a robust water treatment system that required BAC filtration only and eliminated the need for a conventional sand filtration stage as well.
