Special Issue Information

Dear Colleagues,

Industrial wastewater treatment remains a critical concern as industries continue to grow and environmental regulations become increasingly stringent. This Special Issue, "New Insights into Industrial Wastewater Treatment," aims to address the latest advancements, challenges, and innovative solutions in the treatment of industrial effluents. 

This edition will feature comprehensive research on emerging technologies, sustainable practices, and case studies that illustrate effective treatment methodologies. Contributions will explore topics such as the development of advanced treatment systems, the integration of green chemistry principles, and the application of novel materials for pollutant removal. By presenting cutting-edge research and practical applications, this Special Issue will provide valuable insights for researchers, practitioners, and policymakers dedicated to improving water quality and safeguarding environmental health.

Conventional wastewater treatment is often insufficient in the case of mature landfill leachate. Among novel methods, internal microelectrolysis (IME) has been recently recognized as an effective method for refractory wastewater treatment. The aim of this study was the evaluation of the impact of various parameters (pH, time, types, ratios of Fe/GAC, H2O2 dose, the time of application and the soaking of GAC in LL) on the efficiency of the IME process applied to mature landfill leachate. As microelectrodes, waste cast-iron chips and granulated activated carbon (GAC) were used. The application of a multi-step treatment of leachates, PC > m-IME > m-IME/H2O2, resulted in 82.1% COD removal and a significant increase in biodegradability (BOD5/COD rose up to 0.39). The optimal parameters were established as follows: pH 3, 120 min, ratio Fe/GAC 40/10 g/g/dm3 and ratio COD/H2O2 = 1/2. The results showed that the PC is a reasonable pretreatment process before IME—the improvement in total COD removal was up to 12.5%. COD removal in the IME process increased with the increase in GAC dose only up to a certain level. Also, too high doses of Fe negatively affected the efficiency of the IME process, which shows that the efficiency depends not only on the dose but also on the mass ratio of Fe/GAC. The addition of H2O2 significantly improved the COD removal effectiveness, especially when it was applied after 120 min of the m-IME process. The results showed also that the soaking of GAC in LL before the process did not eliminate the sorption process. Full article
