Activities such as water treatment, mining and dredging produce enormous volumes of semi-solid waste annually. The safe and environmentally responsible management of these wastes is costly, consumes vast quantities of water, and sterilises large areas of land. We will address these issues through understanding and manipulating the interaction between individual particles in these slurries to produce desired engineering outcomes. This will be done by developing a laboratory testing column in which the gain in strength and rigidity of a settling slurry are fully characterised, enabling an improvement in design of safe and economical impoundment structures for these waste materials.

水处理、采矿和疏浚等活动每年产生大量的半固体废物。对这些废物的安全和环境负责的管理是昂贵的，消耗大量的水，并消毒大片土地。我们将通过理解和操纵这些浆料中单个颗粒之间的相互作用来解决这些问题，以产生所需的工程结果。这将通过开发一个实验室测试柱来完成，在该测试柱中，沉降浆料的强度和刚度的增加被充分表征，从而能够改进这些废料的安全和经济的蓄水结构的设计。
