Special Issue Information

Dear Colleagues,

Mathematical and statistical modeling of the wastewater treatment process has gained increased interest and use for its numerous benefits in various domains such as plant design, process optimization, operational management, and system control. Mathematical modeling can test hypotheses about the system, convey system knowledge among engineers, and predict future system states. Accurate modeling technologies have become more important in interpreting wastewater treatment processes and identifying microorganisms' complex biological interactions in response to diverse pollutants and their associated regulations for a sustainable environment.

This Special Issue of the journal Water, “Mathematical and Statistical Modeling Methods in Wastewater Treatment”, aims to cover the development and application of modeling methods in wastewater treatment, including mathematical, statistical, and artificial intelligence (AI) approaches. Several major topics include:

  • Modeling, numerical analysis, and simulation;
  • Biological, physical, and chemical phenomena modeling;
  • Mathematical programming;
  • Statistical process analysis;
  • Wastewater treatment process operation and management;
  • Water digitalization, data analytics, and water informatics;
  • Novel technologies and their applications for control and optimization.

The topics are not limited to mathematical and statistical modeling; other topics related to wastewater treatment modeling and computing technologies are welcome.

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).

The quality of water and its impact on consumers’ health has been studied extensively, along with concerns surrounding the use of polyethylene terephthalate (PET) packaging. This research aimed to analyze consumer behavior regarding water consumption patterns, with a focus on sustainability, packaging preferences, and perceptions of drinking water quality. Two surveys, conducted in 2019 and 2024, used a 23-question structured questionnaire to assess the public willingness to prevent water waste in the context of the circular economy. The surveys addressed consumer identification, drinking water preferences, the awareness of alternative consumption methods, and the openness to sustainable solutions such as water filters. Key quantitative findings showed a 10.4% increase in the amount of bottled water purchased in a single trip and a 12.1% rise in the frequency of weekly purchases, particularly among women and younger consumers. Simultaneously, a 4% increase in the preference for PET packaging over glass raised concerns about environmental sustainability, while the preference for tap water dropped by 5%, correlated with a 4.2% decline in the perceived tap water quality. The brand preference also shifted notably, with Aqua Carpatica rising to 38% and Borsec declining from 37% to 16%, reflecting the influence of purity-focused marketing. The novelty of the approach lay in identifying emerging trends related to sustainability, health, and circular economy principles. A comparative analysis of Romanian citizens’ responses over time highlighted changing perceptions of water use and waste reduction. To support the analysis, 13 statistical indicators were evaluated, a Spearman correlation test was applied to 13 criteria, descriptive statistics were computed, and a t-test was conducted across eight hypotheses.
