Aggregation and removal of microplastics and nanoplastics using conventional and alternative coagulants

Small plastic particles (microplastics and nanoplastics) are found in oceans, lakes, and rivers. Their effects on organisms and human beings are still unknown. Microplastics and nanoplastics found in the environment will be weathered, coated, and/or fragmented. Yet, the effects of these modifications on microplastic and nanoplastic removal during water treatment are yet to be thoroughly understood.
The objective of this project is to understand how the efficacy of coagulants is affected by changes in the surface of microplastics and nanoplastics. We will induce these changes by coating the particles with organic matter as well as weathering the particles. Maximizing the removal of these more realistic plastic particles will allow our partner to assess their coagulants and thus recommend what products are best for targeting microplastics and nanoplastics.
