Special Issue Information

Dear Colleagues,

In 2014 we celebrated 100 years of the activated sludge process for wastewater treatment, and this celebration trigged several discussions about the future of the activated sludge process and future developments in wastewater treatment. Personally, I am of the opinion that the activated sludge process is the backbone of our treatment infrastructure and that the vast majority of wastewater treatment plants (WWTPs) will continue to rely on the activated sludge process in its many variants. It is a well-established and well-researched technology that treats our wastewaters reliably for an affordable price.

However, to set up our treatment processes for the requirements of the future, we need to consider additional treatment steps that can supplement our currently implemented technologies and allows us—more than today—to design fit-for-purpose treatment concepts. Regarding the effluent quality, such technologies need to be able to deal with chemicals of emerging concern, microplastics, and antibiotic resistance. At the same time, we need to recover more of the valuable resources that are contained in our wastewaters, including nutrients such as phosphorus.

This Special Issue of Water seeks the submission of papers that focus on advanced wastewater treatment as an additional treatment step after conventional WWTPs as well as nutrient recovery processes that can be implemented into existing process schemes as add-on 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. 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.

The loading of granular activated carbon (GAC) is influenced by the amount of water treated and the concentrations of adsorbates present in the water matrix. Through extraction experiments, we aimed to investigate the total adsorbed mass of eight organic micropollutants by using ethanol as solvent and the maximum possible concentrations, due to the desorption of organic micropollutants, in water. Three different drying methods and the impact of the contact time, GAC particle size, and GAC/solvent ratio were investigated. Although no significant differences between the drying methods could be observed, the chosen contact time and particle size had a significant impact on the amount of organic micropollutants extracted. Lower GAC/solvent ratios positively affected the extraction yield. The masses extracted in ethanol were compared with the cumulated masses calculated from 72 feed and effluent samples, collected during filter operation, resulting in extraction yields between 0.5% and 30%. The composition of extracted micropollutants in ethanol reflected the concentrations in feed water of the pilot-scale filter. Desorption in water was mostly influenced by the solubility of the investigated micropollutants. The same substances found in the supernatants inf the experiments could also be identified in the backwash water of the filter. Full article
