Advances in Water Purification Technologies Innovations and Challenges Using TOPSIS Method

In recent years, tremendous improvements have been made in water filtration technology to meet both the increasing complexity of water contaminants and the increasing demand for clean water. Technological advances in this field include a wide range of approaches and materials, from innovative oxidation methods and filtration techniques to the combination of nanotechnology and biomimetic membranes. These technologies have increased the effectiveness and efficiency of removing various contaminants such as organisms, heavy metals, microplastics and pharmaceuticals. The discovery of new materials such as graphene oxide and carbon nanotubes has improved membrane technologies such as reverse osmosis and nanofiltration. In addition, the development of electrochemical techniques such as capacitive deionization and electrocoagulation enabled energy-efficient solutions for desalination and heavy metal removal. Photocatalytic purification, which uses minerals such as titanium dioxide, has emerged as a strong technology for breaking down organic contaminants by creating reactive oxygen species when exposed to light. Despite these advances, the profession still faces significant challenges. One key barrier to broad acceptance of new technologies was their economic feasibility, particularly in poor countries with limited infrastructure and financial resources. Furthermore, the sustainability of these technologies is being called into question due to their high energy requirements and the risk of releasing secondary pollutants. To address these challenges and ensure that water purification technology can meet future requirements in a sustainable and fair way, sophisticated monitoring systems must be included, as well as a comprehensive approach to water management. In conclusion, even though water filtration technologies have advanced significantly, more research and development are needed to solve the operational, financial, and environmental issues that arise with these advancements. Synergistic integration of many technologies optimized for performance, economy, and low environmental impacts the key to the future of water purification.
