Special Issue Information

Dear Colleagues,

Industrial production in human society has generated large amounts of refractory organic wastewater, such as pharmaceutical wastewater, printing and dyeing wastewater, coking wastewater, and mining wastewater. Due to the existence of various refractory and toxic organic pollutants, the discharge of these organic wastewaters has caused severe natural water pollution, threatening the safety of water resources worldwide. Therefore, effective organic wastewater treatment is the critical step to obtaining a clean water environment for human beings.

The purpose of this Special Issue is to promote the effective treatment of organic wastewater through various treatment methods. Specifically, it is interested in studies concerning the synthesis and application of adsorbents and heterogeneous Fenton-like catalysts, the enhancement of physical fields such as microwave and ultrasonic waves, the reuse of industrial solid waste in organic wastewater treatment, and electro-assisted advanced oxidation technologies.

In this Special Issue, original research articles and reviews are welcome, especially studies focusing on the treatment of real organic wastewater. Research areas may include (but are not limited to) the following:

  • Synthesis and application of adsorbent, Fenton-like, and electro catalysts;
  • Removal of organic pollutants (including novel pollutants) by adsroption, Fenton-like, and electro-assissted processes;
  • Application of physical field in the degradation of organic pollutants;
  • Removal, recovery, and resource conversion of excess nutrients from water/wastewater;
  • Transfer and environmental behavior of microplastics in soil groundwater.

We look forward to receiving your contributions.

The growing demand for effective water treatment solutions, particularly in smaller communities in Brazil, highlights the potential of ozonation. However, implementing this technology at a smaller scale presents challenges, including the need to adapt it for compact systems and optimize processes for both efficiency and feasibility. This study investigates the use of a corona discharge ozone generator operating at 60 Hz in compact systems. Experiments evaluated ozone production at different gas flow rates (0.2 to 1.0 L of ozone-containing gas per minute), with the total flow divided between two lines, A (60%) and C (40%), for simultaneous treatment applications. Mass balance tests were performed using caffeine (CAF) and atenolol (ATL) as model compounds to assess molecular interactions. The results highlight the need to stabilize ozone generation to ensure consistent production and process efficiency, confirming ozone’s effectiveness in degrading emerging compounds (ECs), CAF and ATL, by approximately 80%, after process optimization using the compact ozonation unit. Key factors such as the position and diameter of the flow divider, diffuser type, and pollutant characteristics were shown to affect gas distribution, head loss, and ozone transfer efficiency. Thus, this work underscores the critical role of system configuration in optimizing ozonation, offering insights to enhance its feasibility for providing safe potable water during water crises and emergencies in Brazil.
