Solar Water Disinfection

Dear Colleagues,

Solar water disinfection (SODIS) is one of the emerging water technologies that can be used widely to treat water at low cost, especially in rural areas of developing countries. In fact, it was recently recognized as an appropriate treatment method for water disinfection by the WHO. Although it is a simple method based exclusively on the use of solar radiation (UV disinfection and solar pasteurization mechanisms) and numerous studies have shown its efficacy disinfecting water, there are still some issues to be solved that could make the use of this sustainable and environmentally friendly technology widespread.

The scope of this Special Issue is based on these issues that need further research. Potential topics include but are not limited to the following:

• Efficacy of solar water disinfection against highly resistant environmental bacteria strains such as Clostridium perfringens.
• User acceptance in real case experiences using solar water disinfection as the main method for drinking water treatment (long-term).
• Low-cost sensors that detect complete water disinfection.
• Application of solar water disinfection to wastewater treatment plants, potential problems, and issues when directly treating the effluent.
• Hybridization with other technologies to overcome the climatic dependence (i.e., how to combine methods to guarantee water treatment on cloudy days).
• Pre-treatment required for solar water disinfection.
• Management of plastic waste when using PET bottles for SODIS in areas where recycling is not implemented.

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. Water is an international peer-reviewed open access semimonthly 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.
