Special Issue Information

Dear Colleagues,

Ensuring access to clean water and sanitation is a fundamental human right and a critical global priority, as emphasized by the United Nations Sustainable Development Goal 6 (SDG 6). Rapid industrialization, population growth, and climate change have intensified the pressure on water resources, leading to the widespread presence of emerging pollutants in surface and groundwater ecosystems. Traditional treatment methods are ineffective in removing emegiing contaminants such as heavy metals, pharmaceuticals, endocrine-disrupting compounds, and microplastics. In this context, chemical treatment technologies offer powerful and versatile tools for advanced water treatment, achieving high removal efficiencies while also enabling the design of more sustainable and sustainable water management systems.

This Special Issue, titled "Water Treatment Technology Based on Chemical Processing", seeks high-quality original research and review articles that address recent advances, innovations, and applications of chemical-based technologies for water and wastewater treatment from an ecological perspective. The aim is to promote scientific contributions that support progress towards global water security, environmental protection, and sustainable development.

Topics include, but are not limited to, the following:

  • Advanced oxidation processes (e.g., Fenton, ozone, photocatalysis).
  • Adsorbents and ion exchange materials with chemical functionalization.
  • Electrochemical and photoelectrochemical water treatment.
  • Nanomaterials and catalysts for water purification.
  • Hybrid systems combining chemical, physical, and biological processes.
  • Kinetics, mechanisms, and modeling of chemical reactions in water treatment.
  • Life cycle assessment and environmental impact of chemical technologies.
  • Pilot-scale and full-scale implementations of chemical treatment systems.

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 250 words) can be sent to the Editorial Office for assessment.

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 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 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.

The presence of pathogens, toxic substances, and excess nutrients in rivers is due to the combination of industrial, agricultural, and livestock farming activities, as well as the absence of wastewater treatment plants and sewerage networks. River degradation is the result of these factors. The results from four monitoring campaigns of water quality, carried out between November 2023 and August 2024, in the rivers of northern Urabá, Colombia, are presented in this paper, and the relationships between physicochemical and microbiological parameters are assessed. Water samples from 16 sites, upstream, downstream, and within urban centers, as well as at the mouths of the Hobo, Zapata, and Damaquiel rivers, and two water bodies flowing into the coastal lagoon of Bahía El Uno are presented. Five water quality factors were analyzed at using Spearman’s correlation analysis (p = 0.005). The results revealed negative correlations between dissolved oxygen (DO) and coliforms (−0.49), and positive correlations between temperature and total dissolved solids (TDS) (0.365). The elevated content coliforms exceeding permissible Colombian standards to total coliforms (˂200 MPN/mL) and thermotolerance (1000 MPN/mL) reached 8,400,000 and 24,000,000 MPN/mL, respectively, indicating that urban discharges increase microbial loads and induce degradation of conditions in the study area.
