Advanced Oxidation-Based Techniques for Heterogeneous Treatment of Sediment and Sludge

Dear Colleagues,

Advanced oxidation processes (AOPs) with a free intermediate radical reaction pathway have attracted much interest in the past few decades for the degradation and mineralization of environmental pollutants. Unlike homogeneous aqueous phrases, heterogeneous mediums, such as various sediments and sewage sludge with more complex environment, make the application of AOPs more challenging. Being affected by a variety of restrictive conditions, such as mass transfer limitations, quenching effect, and substance distribution, the control and treatment of environmental pollutants by traditional AOPs often cannot reach the prospective goal, especially when various emerging pollutants continuously appear in such environmental mediums. Although systematic studies surrounding the related issues, such as performance optimization and reaction behavior and mechanisms have been performed, they are still not sufficient to define the internal superiority of used technologies and potential obstacles to full-scale application. Not limited to the above scopes, this Special Issue aspires to collect novel studies covering a broad range of topics, including contaminant (e.g., organic refractory pollutant and heavy metal) speciation, migration and transformation of pollutants in various sediments and sewage sludge, oxidation enhancement, interaction effect; system integration and compatibility with advanced physical-chemical and biological technologies, environmental and ecological risk evaluation, cost-performance analysis, and large-scale and/or practical application. This Special Issue aims to find starightforward, environmentally friendly, flexible, and cost-effective solutions and provide theoretical support for the implementation and application of AOPs to the heterogeneous treatment of sediment and sludge.

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. Sustainability 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 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.
