Innovative Nanomaterials in Wastewater Treatment for Pollutant Removal

Dear Colleagues,

Environmental pollution has become a global issue because of rapid industrial development and the exponential growth of the human population. In particular, water pollution directly causes dramatic damages to the environment as well as human life. Environmental pollution is also one of the world's leading causes of diseases and premature deaths. It is estimated that 9 million deaths in 2015 were caused by all types of pollution, accounting for approximately 3 times more deaths than malaria, tuberculosis and AIDS, and representing 16% of all deaths worldwide, 15 times more than all other violent deaths including in wars. The diseases caused by pollution are accountable for one in four deaths in many affected countries all over the world.

Many methods have been reported in the literature for the removal of organic dyes and heavy metals from water and wastewater, including ion exchange, membranes, adsorption, precipitation, reverse osmosis, coagulation–flocculation, ozonation, electrochemical oxidation, and biological treatment. Among all the methods, the most preferred option depends on factors such as the low cost of processing, high efficiency, fast and easy separation, absence of secondary pollution, and high recyclability. The applications of innovative advanced nanomaterials in wastewater treatment have been increasing every day. The water treatment plants are becoming smaller in size but more effective in their functionalities at reduced cost. This all is due to the advancements in nanotechnology. The present Special Issue aims to critically review the advancements in nanomaterials that are applicable in water treatment to provide insight and benefit to the readers of journal.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Separations is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
