  3. 2. Removal Characteristics of Fibrous and Particulate Microplastics : A Study of the Effectiveness of Coagulation-Flocculation- Sedimentation

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Amrith Kumar; [2022]
    Keywords : Coagulation; flocculation; jar test; microplastics; sedimentation; water treatment; Burktest; flockning; koagulering; mikroplaster; sedimentering; vattenrening;

    Abstract : The rapid proliferation of microplastics (MPs) over the last few decades have raised alarms about the major environmental and health impacts posed by this anthropogenic source. The widespread propagation and transport of MP particles in water sources have accelerated the need to study the eco- toxicological impacts as well as the efficacy of various removal mechanisms from these critical water sources.
