Summary

This study evaluated physical and biological treatment processes for removing emerging pollutants, including microplastics, from wastewater, comparing removal efficiencies across treatment stages and identifying steps where plastic retention is greatest.

Over 2 million tons of emergent pollutants are currently resident in the aquatic ecosystem, some of which potentially end up in treatment facilities. Emergent pollutants like pesticides, hormones, microplastics, personal care products, and pharmaceuticals are of main concern due to their environmental recalcitrance and a major effect on ecosystems and the overall health of humans. This study presents a notion that illustrates contemporary strategies for the removal of such wastes from treatment facilities as well as the prospects of such strategies and possible challenges. Waste removal strategies which include physical and biological removal strategies are fundamental for environmental sustainability. Some of the physical removal strategies encompass sedimentation, floatation, and solidification/stabilization, while the biological removal strategies comprise activated sludge, trickling filters, etc. These removal strategies are either applicable to the primary or secondary phase of waste treatment. The overall waste management techniques steer towards minimizing ecological risks for possible environmental protection and sustainability.
