Development of a schwarzite-based moving bed 3D printed water treatment system for nanoplastic remediation

Abstract

The impact of micro and nanoplastic debris on our aquatic ecosystem is among the most prominent environmental challenges we face today.

Environmental challenges of COVID-19 pandemic: resilience and sustainability – A review

“…To remove nanoplastics from wastewater and drinking water, both stable methods including filtration, centrifugation, membrane separation, biodegradation, coagulation, and sedimentation, as well as more innovative technologies such as advanced oxidation processes, are used ( Devi et al, 2022 ). The removal of nanoplastics/microplastics is made possible by advanced filtration techniques namely membrane filtration and ultrafiltration ( Gupta et al, 2021 ). Interestingly, the filtration process of drinking water with sand and granular activated carbon with a coagulation process improved the removal of nanoplastics to >99%, where it only removed 88.1% of nanoplastics without coagulation ( Arenas et al, 2022 ).…”

Panacea for the nanoplastic surge in Africa: A state-of-the-art review

“…Various other physical and chemical remediation techniques for NPs using electrosorption [ 175 ], photocatalysis [ 176 ], biochar [ 177 ], including a schwarzite-based moving bed 3D printed water treatment system [ 178 ], have been documented. Beside the schwarzite-based moving bed 3D printed water treatment system, these techniques are inexpensive and easy to apply for large scale removal of NPs in Africa, however, the time required is a major drawback.…”
