Dear Colleagues,

The subsequent and rampant use of synthetic compounds in process industries has led to occurrence of these bio-recalcitrant compounds in surface waters/drinking water. Most of these contaminants are persistent to environment and escalates the worldwide pollution of aquatic systems. Generally, it has become one of the life-threatening environmental problems that needs to be addressed immediately. In spite of many published works regarding the presence of these contaminants, even in drinking water, the conventional treatment methods are being relied in most of the countries. Replacement of traditional water treatment methods with efficient advanced, water-treatment technologies is needed to improve the quality of treated water. Various advanced oxidation processes (AOPs), including heterogeneous photocatalysis and homogenous photo-Fenton processes, have proven their effectiveness for wastewater detoxification. However, the artificial sources of UV radiation in these treatment processes cause the majority of the maintenance and operating costs of the treatment unit, due to the consumption and regular replacement of UV lamps. Therefore, using natural solar radiation instead of artificial lamps is an environmentally-attractive and economical solution for photocatalysis or photo-Fenton-like processes. The applications of solar-driven photocatalytic reactors fit well for countries that receives immense amounts of solar light throughout the year. Besides, solar treated water find applications in heat exchanger employed in diverse fields of engineering - be it electronic cooling, automotive engine cooling, HVAC etc. Solar treated water when mixed with nanofluids serves as coolants in heat exchangers and have attracted significant focus of the researchers. 

This Special Issue on "Solar Detoxification of Wastewater and Its Subsequent Applications" seeks high-quality works and topics focusing on the latest novel wastewater treatment processes using solar radiation, including, but not limited to, photocatalytic treatment, photo-Fenton, biological, water disinfection, oxidation, filtration, purification, etc., as well as practical applications of these technologies.

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. Processes 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 2400 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.
