Dear Colleagues,

Since the turn of this century, global water consumption has increased by over 600%. A large percentage of this increase could be attributed to the rapid development of industrial facilities. In most industries, the majority of water consumed is disposed of as industrial wastewater (IWW). Humans and our ecosystem are adversely affected by IWW releases into the environment. It is, therefore, necessary to explore options to obtain enough water for industrial development as well as ensure adequate treatment of IWW to comply with increasingly stringent discharge standards. A suitable option for meeting both challenges is to reclaim treated industrial effluent. New knowledge must be developed by the research community to fulfill this vision, such as innovative technologies for treating and reclaiming different types of wastewater, resource recovery from wastewater, etc.

The characteristics of IWW are much more variable and contain numerous inorganic and organic pollutants. It is, therefore, often inadequate to rely solely on biological treatment technologies for meeting stringent discharge standards of treated IWW. There are also alternative methods for treating recalcitrant organics, including advanced oxidation processes (AOPs) and separation processes. However, AOPs usually consume a large amount of energy (e.g., ozone generation and UV radiation) and chemicals (e.g., oxidants and catalysts), making them an expensive process. Meanwhile, separation processes (such as adsorption, filtration, and ion exchange) have been applied to the removal of pollutants and resource recovery, but there is still a need for innovative strategies to reduce their costs. Thus, the development of innovative technologies and building on existing technologies for IWW treatment and reclamation are therefore required.

This special issue will focus on the novel technologies and integrated processes for IWW treatment towards resource reclamation, e.g., water reuse and nutrient recovery. Research related to new developments in existing technologies for IWW treatment is also covered. Moreover, the issue focuses on meeting the needs of the industrial sector from a global perspective, which is a key aspect of sustainable water management. Scientific knowledge collected through this special issue will be valuable to the engineering community as it pertains to the treatment and reclamation of IWW. Research papers and reviews, not limited to, are welcome in the following areas:

• Industrial wastewater treatment systems
• Innovative and integrated technologies for IWW treatment
• Resource recovery and water reuse from IWW
• Advanced strategies for IWW management
• Proven case studies for treatment and reclamation of IWW
• Environmental and human health effects of IWW and their mitigation
• Bio-processes to produce platform chemicals from wastes
• Life-cycle assessment

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.
