Special Issue Information

Dear Colleagues,

With the rapid development of industrialization and urbanization, emerging contaminants such as pharmaceuticals, personal care products, endocrine-disrupting compounds, microplastics, and per- and polyfluoroalkyl substances (PFASs) are being detected with increasing frequency and concentration in aquatic environments. Due to their potential ecological toxicity, bioaccumulation, and resistance to degradation, these substances pose severe challenges to drinking water safety, ecosystem health, and human well-being. Conventional water treatment processes often fall short when addressing these complex, low-concentration yet highly active pollutants. Therefore, developing efficient, sustainable, and economically feasible control technologies for ECs has become a cutting-edge research priority and an urgent demand in the fields of environmental science and engineering.

This Special Issue aims to gather the latest research findings and innovative advances from scholars worldwide on control technologies for emerging contaminants. We invite researchers to submit original research articles, review papers, and frontier technology reports, collectively exploring comprehensive solutions along the entire chain—from source reduction and process interruption to end-of-pipe treatment.

Topics of interest for this Special Issue include, but are not limited to, the following:

  • Detection, risk assessment, and policy management of ECs;
  • Multi-technology-coupled processes;
  • Green and sustainable technologies;
  • Bioaugmentation and novel biological treatment approaches;
  • Advanced adsorption and separation materials;
  • Advanced oxidation/reduction technologies.

Catalytic ozonation has been widely utilized in environmental applications, such as the removal of pharmaceutical active compounds (PHACs) from wastewater, due to its outstanding catalytic efficiency. To further enhance its performance and expand its practical application, ozone-based hybrid processes have been investigated, including ultraviolet radiation/ozonation, hydrogen peroxide/ozonation, ultrasonication/ozonation, and biological treatment/ozonation. Ozone degrades pollutants via two primary pathways: direct oxidation (via molecular ozone) and indirect oxidation (via reactive intermediates). Enhancing ozone decomposition into various reactive oxygen species (ROS), predominantly hydroxyl radicals, can significantly augment the degradation efficiency of pollutants. The surface adsorption and electron transfer processes of catalysts can promote ozone activation and decomposition into ROS to achieve the efficient degradation and mineralization of pollutants. Among catalysts, Mn-based catalysts have been extensively studied in past research. They have demonstrated exceptional performance when combined with other metals, such as Mn/Ce, Mn/Fe, and Mn/Co, etc., due to synergistic effects arising from bimetallic interactions. The inherent characteristics of catalyst supports may also influence the generation process of ROS. Choosing an appropriate support is conducive to promoting the uniform distribution of catalytic active sites on the catalyst surface and avoiding the agglomeration of metal particles, and it is also beneficial for the recovery and reuse of the catalyst. Furthermore, coupling catalytic ozonation processes with techniques like high-gravity technology, jet reactor systems, and micro–nano-bubbles can improve the utilization efficiency of ozone by exploiting gas cavitation effects. In this paper, we summarize the research progress in the degradation of PHACs using catalytic ozonation and discuss strategies for improving the mass transfer efficiency of ozone in water. Finally, the challenges and opportunities associated with applying catalytic ozonation in practical applications are also discussed. Full article
