Special Issue Information

Dear Colleagues,

Water monitoring and treatment technologies play pivotal roles in guaranteeing water safety and fostering sustainable development. The evolution of monitoring strategies and treatment technologies (e.g., the monitoring of water environments, the removal of contaminants, the integration of diverse treatment processes in water treatment, etc.) has driven innovation and optimization across various facets of water management. However, to enable a more harmonious coexistence between humanity and nature, efforts are still needed to accomplish the ultimate goal of pollution interception and emission reduction through more ecological and systematic approaches.

This Special Issue titled “Advanced Water Monitoring and Treatment Technologies” seeks novel and high-impact research pieces with particular interests in the monitoring of water environments, the removal of contaminants from water, and highly effective water treatment integration systems using more ecological and systematic approaches. Topics of interest include, but are not limited to, the following:

  • Water environmental monitoring and early warning systems.
  • Aquatic ecological survey and assessment.
  • Emerging materials and technologies for heavy metal removal.
  • Advanced adsorption and separation processes for emerging pollutants.
  • Developments in technologies and integrated processes of sediment and contaminated water.

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. 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.

Wastewater treatment plants (WWTPs) play a crucial role in treating sewage, which undergoes multiple treatment stages to ensure a safe treated effluent. However, any interference during these stages can compromise the final effluent quality. Such is the case of the overgrowth of the microcrustacean Daphnia spp., known to inhabit WWTPs, but with its presence in the decantation stage negatively impacting effluent clarification and further disinfection. This study aimed to evaluate how the effluent quality parameters influence the occurrence of Daphnia spp. in the secondary decanter of a WWTP. Wastewater monitoring data collected from 2017 to 2022 were analyzed. Firstly, as the COVID-19 pandemic occurred during the studied period, it was assessed whether the quality and load of the raw wastewater changed. Subsequently, an analysis was carried out using multivariate statistical methods for all the steps of WWTP. Comparing the periods before and during the pandemic, the raw wastewater volume decreased by 19.58%, and the BOD, COD, and TSS decreased by 37.78%, 16.86%, and 35.75%, respectively. These were the parameters affected the most. The statistical analysis revealed correlations between the presence of Daphnia spp. and specific effluent quality parameters, including raw wastewater BOD values below 500 mg L−1, treated effluent BOD values below 13 mg L−1, and pH levels exceeding 7.3. Additionally, BOD and pH were highlighted as critical parameters influencing their presence or absence. Full article
