Special Issue Information

Dear Colleagues,

With the continuous growth of the world's population and rapid industrial and commercial developments, there has been a corresponding rise in the generation of domestic, commercial, and industrial wastewater. The pollutants in these wastewaters unquestionably pose a significant threat to the environment. Moreover, the development of new materials (nanomaterials, pharmaceuticals, PFAS, electronics, etc.) has engendered the emergence of pollutants that challenge existing and conventional wastewater treatment methods. Nevertheless, these wastewaters still serve as a resource for the production of high-value products and will play a critical role in the development of circular economies. This Special Issue aims to collate research and review papers that discuss with the following topics:

  • Advances in the materials and processes associated with wastewater treatment;
  • Innovations in wastewater treatment and future perspectives;
  • The treatment of emerging pollutants;
  • Resource recovery and bio-energy/material production in wastewater treatment operations;
  • The sustainability of wastewater treatment processes.

The study assessed the influence of pyrolysis temperature on the properties of hickory sawdust and peanut shells based biochar, particularly its pore structure, surface functional groups, and adsorption capacity. Results from SEM analysis demonstrated that higher pyrolysis temperatures led to an enhanced pore structure and surface roughness in biochars, providing increased adsorption capacity. Raman spectrum analysis revealed higher levels of disorder and graphitization in biochars pyrolyzed at elevated temperatures. Quantification of surface functional groups using the Boehm method indicated a shift in the abundance of basic and acidic groups under high pyrolysis conditions. Employing the FHH model, fractal characteristics were observed in the pore structure of different biochars, with high-temperature biochars displaying increased disorder. The study also explored the mechanism of SMX adsorption onto biochars, revealing higher adsorption capacity for biochars with richer pore structures and rougher surfaces. The Elovich model proved to be the best fit for describing the chemisorption process of SMX onto the biochars. Moreover, the study demonstrated the impact of urine ions on SMX adsorption onto the biochars. These findings provide valuable insights into the properties and potential applications of biochars in environmental remediation. Full article
