Landfill Leachate Treatment with Ozone and Hydrogen Peroxide, Pilot Scale

Two leachates from the São Leopoldo landfill in Rio Grande do Sul were treated on a pilot scale, processing 460 liters per test over 96 hours. The study by Luciana Paulo Gomes evaluated the removal of recalcitrant compounds using ozone and ozone combined with hydrogen peroxide. High removals of apparent color, chemical oxygen demand, and total organic carbon were observed, reaching 99%, 88%, and 66% respectively.

Use Cases

• Modeling the efficiency of ozone-based advanced oxidation processes based on initial BOD, COD, and TOC concentrations.
• Comparing treatment outcomes for raw versus pre-treated landfill leachate based on the study's experimental setup.
• Analyzing the marginal benefit of adding hydrogen peroxide to ozone treatment based on the reported efficiency increases.

Strengths

• Pilot-scale experimental data treating 460 liters of leachate per test, providing realistic process conditions.
• Reports specific removal percentages for key parameters like apparent color (99%), COD (88%), and TOC (66%).
• Compares two distinct leachate types (raw and treated) and two treatment methods (O3 alone and O3+H2O2).
