Special Issue Information

Dear Colleagues,

As many of you are already aware, we are increasingly surrounded by organic compounds found in products we use daily. Many of these compounds are commonly detected in wastewater treatment plants (WWTPs), including pharmaceutical and personal care products. In addition, plasticizers, flame retardants, herbicides, pesticides, and other substances are also present. For this reason, the new European Union directive mandates the implementation of a quaternary treatment in WWTPs to eliminate emerging pollutants. Although these substances are typically found in very low concentrations, they can still pose significant adverse effects.

This special volume invites papers focused on monitoring emerging pollutants in WWTPs, including studies on their sources, occurrence, and concentrations, as well as papers that assess the risks associated with these pollutants. We also welcome contributions to the development of new analytical methodologies for analyzing complex waters such as wastewater, studies investigating the efficiency of various wastewater treatment processes, and research on transformation products formed during these treatments.

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.

Dyes are widely used in various industries, but their removal from wastewater remains a challenge due to their resistance to biodegradation. While substantial research exists regarding the removal of individual dyes, there is much less about the removal of their mixtures. The aim of the research was to determine the possibility of using the immobilised mycelium of Pleurotus ostreatus strains to remove three-component mixtures of dyes from different classes. Efficiency of the removal in the continuously aerated reactor was similar to that obtained in a periodically aerated reactor and was over 90% at the end of each cycle. Despite the addition of subsequent portions of dyes, no increase in the toxicity of post-process samples was observed, and even a decrease in zootoxicity was noticed. The results of the study therefore indicate that an immobilised biomass can be used to remove the dyes, without the need to constantly inject air into the reactor. Full article
