Application of nanomaterials as remediation solutions in wastewater treatment

Access to clean water is crucial to all living creatures in the world. Due to a lack of water resources, wastewater treatment has increasingly become an essential venture for quality drinking water and water for varied purposes to be made available. The lives of terrestrial and aquatic organisms are seriously threatened by incessant wastewater generation containing harmful chemicals, which are also a major to public health and the ecological environment. The application of nanomaterials in wastewater treatment has recently become a subject of extensive because of their novel properties. This chapter, therefore, provided an overview of the current developments in the widely utilized nanomaterials that are environmentally friendly in wastewater treatment. Also, it offered a critical evaluation of the green isolation of nanomaterials and their relevance in effluent treatment for eliminating dangerous emerging pollutants like plastic microbeads and pharmaceutical waste. This article also provides an overview of synthesized nanomaterials using various chemical and environmental-friendly production techniques. The distinctive characteristics, appropriate application, potential benefits, and existing limitations of green nanotechnology in wastewater treatment are also carefully examined. Concentrating on potential research issues presents a fresh viewpoint on nanotechnology for wastewater treatment applications. Furthermore, this chapter promotes moving ahead toward effective sustainable development goals (SDGs) 6 and 12, addressing “Clean water” and “Responsible Consumption and Production,” respectively. Finally, to stimulate the thinking of scholars in this discipline, hypotheses on potential directions for the future or opportunities that need to be explored will be offered.
