Dear Colleagues,

Industrial wastewater generally has a complex chemical composition, requiring robust and effective treatment processes before being discharged into the environment. In recent years, both compliance with environmental legislation and the reuse of treated effluent have become objectives to be achieved by industries to take advantage of wastewater in the industrial process itself.

Depending on the industry and its production processes, the wastewater’s quality and volume can vary widely. Both biodegradable compounds and recalcitrant and toxic substances can be present in the aqueous matrices generated by industries, both in dissolved and particulate form.

Several approaches can be used for the treatment of industrial waste streams, such as physicochemical, biological, and advanced oxidation processes. In most applications, the best solution is a combination of several techniques in order to achieve greater treatment efficiency and cost reductions. However, selecting the best technically and economically viable solution is always a challenge. The most suitable approach to choosing the most effective treatment method depends on each case. Therefore, it is essential to characterize the wastewater to reveal the main components that compose it before implementing any treatment process.

For this Special Issue, we welcome high-quality studies on the treatment of industrial wastewater by conventional and advanced methods. Works involving combinations of processes are preferred. Besides technical reports, survey papers and reviews are also welcome. A list of types of industrial wastewater to be covered within this Special Issue is presented below (besides these, other types of wastewater can be suggested by authors):

- textile wastewater;

- tannery wastewater;

- brewery wastewater;

- pulp and paper industry wastewater;

- mining industry wastewater;

- food industry wastewater;

- chemical industry wastewater;

- oil and gas industry wastewater;

- petroleum refinery and petrochemical industry wastewater;

- iron and steel industry wastewater;

- nuclear industry wastewater.

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. 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.
