Special Issue Information
Dear Colleagues,
Global water scarcity, driven by climate change, population growth, and increasing demand, has intensified the need for innovative solutions to secure freshwater resources. The reuse of unconventional water sources, such as treated wastewater, has become essential, particularly for applications like agricultural irrigation. However, the development of efficient, sustainable, and cost-effective treatment technologies is critical to ensuring that treated water meets safety standards and is suitable for reuse. Photocatalysis, an advanced oxidation process (AOP), has emerged as a promising solution for water treatment due to its ability to degrade organic pollutants and inactivate microbial contaminants. Recent advancements in photocatalytic materials, combined with low-cost adsorption technologies, present effective and energy-efficient alternatives to conventional treatment methods.
In addition to large-scale treatment solutions, there is a growing need to develop decentralized, low-cost systems for treating wastewater in rural or underserved areas. These systems, based on AOPs and adsorption, offer practical, scalable solutions for local communities by reducing infrastructure costs and enhancing accessibility to clean water. However, challenges remain in optimizing these processes for practical application, including material cost, scalability, system reliability, and efficiency.
This Special Issue aims to showcase the most recent advances in photocatalytic and adsorption-based technologies for decentralized wastewater treatment, with an emphasis on their application to unconventional water reuse in agriculture and other sectors. We invite original research and review articles that focus on innovative and cost-effective solutions for water treatment.
Topics of particular interest include, but are not limited to:
- Photocatalytic degradation of organic and inorganic pollutants;
- Development and characterization of novel photocatalytic and adsorbent materials;
- Low-cost decentralized wastewater treatment systems using AOPs and adsorption;
- Mass transfer dynamics and reactor modeling;
- Pilot-scale applications and real-world case studies in decentralized systems;
- Design and optimization of decentralized treatment processes for sustainable water reuse;
- Reuse of treated wastewater in agriculture and other sectors.
We encourage contributions that explore hybrid and integrated systems for more effective, affordable, and energy-efficient water treatment, with a focus on sustainable water management and the circular economy.
