Special Issue Information

Dear Colleagues,

Water is the source of all life on this blue planet, and it creates and shapes everything in its current form. All human activities and social operation are inseparable from clean water. With the boom in population and rapid industrialization, we are now facing a more severe clean water crisis than at any other time in history. In the past decades, a large number of meaningful works have been conducted on effective water/wastewater treatment, but great challenges and research gaps still remain in this area, which also provide numerous opportunities for a new generation of scientists. 

This Special Issue of International Journal of Environmental Research and Public Health (IJERPH) is seeking original works on all aspects of “Effective Water/Wastewater Treatment Methodologies for Removal of Pollutants”, including but not limited to physical separation, chemical degradation, biochemical conversion, ecological purification, dedicated treatment, digital wastewater treatment, water/wastewater recovery and reuse, etc. Research papers and reviews covering novel findings are welcome, and interdisciplinary works are especially welcome.

Safe drinking water remains a major global challenge, especially in rural areas where, according to UNICEF, 80% of those without access to improved water systems reside. While water, sanitation, and hygiene (WASH)-related diseases and deaths are common outcomes of unsafe water, there is also an economic burden associated with unsafe water. These burdens are most prominent in rural areas in less-developed nations. Slow sand filters (SSFs), or biological sand filters (BSFs), are ideal water treatment solutions for these low-resource regions. SSFs are the oldest municipal drinking water treatment systems and improve water quality by removing suspended particles, dissolved organic chemicals, and other contaminants, effectively reducing turbidity and associated taste and odor problems. The removal of turbidity and dissolved organic compounds from the water enables the use of low-cost disinfection methods, such as chlorination. While the working principles of slow sand filtration have remained the same for over two centuries, the design, sizes, and application of slow sand filters have been customized over the years. This paper reviews these adaptations and recent reports on performance regarding contaminant removal. We specifically address the removal of turbidity and microbial contaminants, which are of great concern to rural populations in developing countries. Full article
