Special Issue Information
Dear Colleagues,
Sludge is an inevitable by-product generated by the transformation of pollutants or sediments converted from pollutants during wastewater treatment or water environment remediation processes. Various toxic substances, such as pathogens, heavy metals, and organic pollutants, make the safe disposal of sludge a crucial step for the secondary pollution control of water pollution control.
High moisture content is one of the main limiting factors of the resource/energy recovery and disposal of sludge. Dewatering can minimize the sludge volume, facilitate the transportation, and increase the calorific value. Thus, dewatering commonly acts as the essential step of different sludge treatment routines. However, sludge presents a stable state with water–solid infiltration, which is difficult to be dewatered without pretreatment.
Aiming at highly efficient dewatering of sludge, the multiple influencing factors on sludge dewaterability should be systematically analyzed and more efforts should be devoted to improving sludge dewaterability by various approaches with minimal consumption of chemicals and energy.
Therefore, this Special Issue aims to consolidate and disseminate knowledge in the field. We invite you to contribute your research article, communication, or review related to the basic theory and technical inovation of sludge dewatering processes.

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. Separations 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 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.
