Separation Technologies and Evaluation Methodologies in Recycling Wastewater for SDG 6

Dear Colleagues,

Wastewater management and reuse are crucial for environmental preservation and water scarcity mitigation. By treating wastewater to high standards, it can be safely repurposed for non-potable uses, conserving freshwater resources and alleviating the burden on treatment plants. This aligns with the circular economy approach in the water sector, promoting responsible resource management. Advanced treatment technologies and monitoring are essential for reliable and cost-effective wastewater reuse. They also help address pollutants of emerging concern like pharmaceuticals, personal care products, microplastics, and PFAS, which pose challenges to wastewater treatment. Robust strategies and research are needed to mitigate their impact on ecosystems and human health. Also, comprehensive wastewater treatment systems, including disinfection and proactive measures against emerging pollutants, ensure environmental preservation and sustainable water management. This approach supports SDG 6, ensuring clean water and sanitation for all.

Through innovative solutions like wastewater reuse, advanced treatment, and circular economy principles, we can address water scarcity, reduce pollution, and achieve SDG 6’s goals. Embracing these practices fosters a sustainable and resilient future.

Therefore, it is my pleasure to invite you to contribute your research article, communication, or review to this Special Issue dedicated to circular economy in the water sector, wastewater treatment and reuse, pollutants of emerging concern, and contributions to SDG 6.
