Microplastics are widely dispersed throughout the marine environment. Millions of tons of lost or discarded plastic items are entering the world’s oceans at a rate that is expected to increase by an order of magnitude by 2025, unless current disposal practices are altered. Microplastics, defined as plastics <5 mm in size, form a numerically dominant component of this anthropogenic debris. These plastics may enter the environment as either primary microplastics, those manufactured to size, or secondary microplastics, which are generated from the breakdown of larger plastic items. Separation of microplastics is therefore a challenging topic. This research project intends to understand the microplastics separation using passive flow control techniques. State of the art flow visualization techniques will be used to investigate novel techniques for microplastics separation from water.

Expected outcome from the Student's work

Removal of micro-plastics is a challenging topics because their size might vary from nanoscale to millimeters. It is therefore difficult to use unique method of separation. In this project we would like to focus on microscale separation. The objective is to design a transparent micro-device to study micro particles separation using micro-channels and micro-flow visualization techniques, such as Micro-PIV, Microscopy and High Speed Photography.

Terms & conditions

Have a background in Fluid Mechanics and the desire and willingness to work on an experimental project in micro-scale.
