The significance of the wastewater treatment, management, and its disposal is gradually increasing in the modern times and it has become a major concern for public health scientific interest. Nanotechnology holds great potential in advancing water and wastewater treatment to improve treatment efficiency as well as augment water supply through safe use of unconventional water sources.

The highly efficient, modular, and multifunctional processes enabled by nanotechnology are envisaged to provide high performance, affordable water, and wastewater treatment solutions that have less reliance on large infrastructures. Nanotechnology-enabled water and wastewater treatment promises to not only overcome major challenges faced by existing treatment technologies but also to provide new treatment capabilities that could allow economic utilization of unconventional water sources to expand the water supply. Nanomaterials were suggested as efficient cost-effective and environmental friendly alternative to existing treatment materials, from the standpoints of both resource conservation and environmental remediation.

We are inviting researchers in the field to contribute their valuable work for the possible publication in the special edition. We invite authors to submit original research and review articles that seek to describe environmental nanotechnologies, monitoring studies and management for water, waste, environmental pollutions as well as delivering solutions to these problems.
