Comparative Analysis of Conventional and Advanced Water Treatment Processes: Efficiency, Sustainability and Innovation

Abstract

This study presents a comparative analysis of conventional and advanced water treatment processes, focusing on their efficiency, sustainability, and innovative aspects. As global challenges such as population growth, climate change, and pollution threaten access to clean water, the need for effective wastewater treatment has become more critical than ever.

Conventional methods like activated sludge processing, chlorination, and constructed wetlands have been foundational in wastewater management. However, these techniques often face limitations in addressing complex contaminants and emerging pollutants. In contrast, advanced technologies—including membrane filtration, advanced oxidation processes (AOPs), electrochemical treatments, and adsorption using novel materials like carbon nanotubes—have shown superior capabilities in removing diverse pollutants. These methods not only enhance contaminant removal efficiency but also offer potential for resource recovery and environmental sustainability.
