Special Issue Information

Dear Colleagues,

The rapid increase in the consumption of industrial products in recent decades has contributed to the comprehensive increase in environmental pollution by various types of chemicals. The subsistence of clean water as the most important resource on Earth is the common interest of the whole of humanity. The permanent development of novel, efficient, innocuous technologies for wastewater remediation represents an inevitable challenge for the entire scientific community. In terms of research and development of wastewater treatment methods, an integral approach that covers both fundamental and practical aspects is necessary so that the removal is complete, sustainable, and safe for the environment, without secondary pollution. Facing the increasing challenges, even the well-established technologies for water purification need improvements and optimization to fit these goals. Bringing together the scientific and technological knowledge with the recognition of the long-range effects of their application should contribute to the finding of optimal solutions that will assure enough safe water for the living world in the near future.

This Special Issue, titled “Advanced Wastewater Treatment Processes and Technologies”, seeks high-quality works focusing on the recent progress in the development of wastewater treatment processes with minimal negative impact on the environment and humanity. Topics include, but are not limited to, the following:

  • The implementation of green materials in wastewater treatment processes.
  • Optimization of wastewater treatment process.
  • Development of the methodologies for the removal of target pollutants.
  • Development of novel materials with potential applications in green technologies.
  • Studies of treatment by-products, secondary pollution, and toxicology.
  • Modelling and simulations.

We look forward to your submissions.

Industrial wastewater contains complex pollutants, including toxic dyes, necessitating effective and sustainable remediation strategies. Conventional treatment methods often struggle to remove multiple dyes simultaneously, underscoring the need for innovative adsorbents. This study investigated a clay/carbon composite (SBE/C (500 °C)) derived from spent bleaching earth (SBE) via pyrolysis for the simultaneous removal of methylene blue (MB) and malachite green (MG) dyes. The pyrolysis process significantly enhanced the specific surface area of SBE, improving its adsorption capacity. Using the Box–Behnken design (BBD) and response surface methodology (RSM), we optimized key parameters (pH, contact time, and dosage) at 45 °C and an initial dye concentration of 20 mg/L. The developed quadratic model demonstrated high predictive accuracy, with experimental results closely aligning with predictions (R2 = 0.9983 for MB, 0.9955 for MG), along with strong adjusted (R2 = 0.9962 for MB, 0.9896 for MG) and predicted (R2 = 0.9811 for MB, 0.9275 for MG) values. Under optimal conditions, the maximum adsorption capacities reached 27.77 mg/g for MB and 27.38 mg/g for MG. These findings highlight the potential of SBE/C (500 °C) as a sustainable and cost-effective adsorbent for the simultaneous removal of MB and MG from wastewater, offering a promising solution for environmental remediation.
