LANDFILL LEACHATE TREATMENT VIA NANO ZERO VALENT IRON PARTICLES (nZVI) OF ADSORPTION PROCESS

Abstract

Landfill leachate (LFL) is a significant environmental threat due to the complexity and diversity of contaminants. There are various physical, chemical, and biological treatment methods recommended for LFL treatment. Magnetic nanoparticles are widely used adsorbents with a successful effect compared to traditional adsorbents. Magnetic adsorbents are adsorbents with suitable stability, high adsorption capacity, high removal efficiency, and reusable capabilities. Nano zero-valent iron (nZVI) is an effective adsorbent to remove contaminants found in wastewater, especially LFL. In this study, nZVI was used in the LFL pretreatment. In the adsorption study, it was tested at increasing concentrations from 50 to 500mg nZVI/L, pHs from 3 to 8, and contact times from 15 to 330 minutes. System performance was evaluated with various pollutant parameters such as chemical oxygen demand (COD), dissolved organic carbon (DOC), total nitrogen (TN), nitrate (NO3-), and ammonium (NH4+) found in garbage leachate. The removal efficiencies obtained at the end of the study were determined as 60%, 60%, 74%, 56% and 33%, respectively. As a result, the optimum conditions for the treatment of LFL by adsorption process using nZVI were determined as 50 mg nZVI/L, pH 8, and contact time 120 minutes.
