ABSTRACT
To develop standard effluents, resource recovery, and prevent overuse of finite freshwater resources, the globe seeks to investigate all wastewater treatment technologies that are now accessible in the face of water shortages. Municipal wastewater remains one of the primary anthropogenic causes for the discharge of contaminants of emerging concern (CECs) into the environment, which can have toxic and harmful impacts on aquatic creatures and by extension, on humans. This paper provides an overview of the cutting-edge and novel technologies that have become popular options for treating urban wastewater towards recovering water for reuse from various wastewater streams. Therefore, membranes, ozonation, activated carbon (AC), and photoelectrochemical technologies are discussed in this review for their potential as effective wastewater treatment choices. However, the consistent deployment and exploitation of all these technologies to address their flaws would, however, require close collaboration between engineers, analytical research scientists, and electrochemists.
