The article "An Extensive Analysis of Combined Processes for Landfill Leachate Treatment" by Ahmad Jamrah, Tharaa M. AL-Zghoul, and Zakaria Al-Qodah reviews the effectiveness of combined treatment processes for landfill leachate (LL), which is a significant environmental concern due to its complex and refractory pollutants. The authors highlight that while conventional treatment processes such as biological, chemical, and physical methods have been used, a single process is often insufficient to meet environmental standards. The review emphasizes the advantages of combined treatment processes, particularly chemical-chemical and chemical-biological combinations, which show promising results in removing pollutants. Key findings include: - Combined processes like MBR with NF, Fenton with adsorption, and PF with biological treatment achieve high removal efficiencies for COD, reaching up to 99%. - The combined Fenton with adsorption process and EC with SPF process enhance biodegradability, increasing BOD₅/COD ratios. - The integration of various treatment processes overcomes the limitations of single processes, leading to more efficient and comprehensive pollutant mineralization. The authors conclude by recommending the implementation of enhanced combined treatment processes to address the environmental concerns associated with LL and contribute to sustainable waste management practices. The review also discusses the methodology, leachate characteristics, and the importance of co-treating LL with wastewater and recycling leachate to improve treatment efficiency and reduce environmental impact.The article "An Extensive Analysis of Combined Processes for Landfill Leachate Treatment" by Ahmad Jamrah, Tharaa M.
