About this Research Topic
The rapidly increasing population, depleting water resources, and climate change resulting in prolonged droughts and floods have rendered drinking water as a competitive resource in many parts of the world. Therefore, any form of water, reuse or recycle will help to mitigate this challenge. The careful management of water and wastewater is a big challenge and “hot” trend of recent research. During the last century, a huge amount of wastewater was discharged into rivers, lakes and coastal areas. This resulted in serious pollution problems in the general term of the aqueous environment. Municipal, industrial, and natural activities produce large quantities of liquid wastes and effluents which pose severe threats to the environment and human health. Thus, it mandatory to find the appropriate technique to efficiently treat and manage water and wastewater.
Some indicative/conventional methods are biological treatments, adsorption, flocculation, oxidation, membranes, filtration, etc. These conventional technologies focus only on the primary wastewater treatment, especially on the physical separation of solid particles and release a high concentration of toxic phosphorus, nitrogen, and other ionic compounds into the environment. For this reason, the latest technology involving Nanotechnology is highly potent in advancing wastewater treatment via Nanomaterials (nanoadsorbents, nanocomposites (photo)catalysts, nanofiltration, nanomembranes, nanoparticles, etc). These nanomaterials have been established in the development of separation membranes, catalytic, and adsorbent materials to enhance the removal of specific components of wastewater and improve productivity. Zero-valent metal nanoparticles (Ag, Fe, and Zn), metal oxide nanoparticles (TiO2, ZnO, and iron oxides), carbon nanotubes (CNTs), nanocomposites and too many other types of nanomaterials are already used in wastewaters treatment. All of the above can be achieved by using Nanotechnology.
For this Research Topic, we invite topical submissions in all areas mentioned above using Nanotechnology. Although all article types will be considered, we particularly welcome Original Research Articles and Reviews.
