Oxidative removal of stabilized landfill leachate by Fenton's process: process modeling, optimization & analysis of degraded products

Abstract

In this study, the stabilized landfill leachate which has a BOD : COD ratio of 0.045 was treated using Fenton's process.

Mechanistic Coupling of Coagulation-Flocculation, and Machine Learning for Removal of Various Contaminants from Water System

“…AI models in predicting the doses of coagulants and biopolymers in coagulation-flocculation processes for the treatment wastewater have been widely investigated by researcher (Matovelle et al 2023). The leachates generated in sanitary landfills contain many pollutants harmful to the environment (Durai et al 2020;Mishra et al 2018). The researchers have used Artificial Neural Networks (ANNs) to determine the doses of coagulants and biopolymers suitable for coagulation-flocculation processes.…”

Fenton-adsorption process for leachates from two landfills (karstic-clays)

“…The optimal contact time for COD and color removal was 5 minutes as shown in the Figure 3. The contact time depends on in turn the pH and the optimal dose, in the literature different experiences with Fenton process are reported where the reaction time varies from 5 min (Durai et al, 2020) to 3 hours (Zhang et al, 2018) in COD removal.…”

Development of a Statistical Model to Predict Methane Production from Waste Activated Sludge Co-Digested with Olive Mill Wastewater and Cattle Dung by Response Surface Methodology

“…The Fenton reaction, which involves hydroxyl radicals as the primary oxidants, is one of the most useful oxidation processes that can effectively degrade various substrates. Although more than a century Henry JH Fenton 1,2 discovered the oxidation of polyhydric alcohols and organic acids during the reaction between Fe(II) and H 2 O 2 ; it is only in recent decades that much more researches have been carried out so far on the Fe 2+ /H 2 O 2 system, whether at the level of the interaction mechanism 3,4 or at the level of applications in the oxidation system of organic pollutants in an aqueous medium, [5][6][7] as well as for different types of water: drinking water, 8 explosives discharges. 9,10 The main advantage of the Fenton treatment is the complete destruction of contaminants into harmless compounds such as carbon dioxide, water and inorganic salts.…”
