Recovery of Copper And Zinc from the Livestock Bio-Sludge with Organic Acid and Hydrogen Peroxide Extraction
Short Introductive summary
This study aimed to reduce copper (Cu) and zinc (Zn) levels in bio-sludge from livestock wastewater treatment by optimizing an eco-friendly organic acid extraction method. A factorial design was employed to test various factors’ impact on extraction efficiency. Results showed that treating dried bio-sludge with 2% H2O2 significantly improved Cu and Zn removal. The most effective removal, achieved with 4N acetic acid over 48 hours, resulted in substantial reductions of Cu and Zn levels. This eco-friendly approach promises to enhance sustainable livestock production systems by mitigating heavy metal accumulation in agricultural soils.
