1. EVALUATION OF THE TREATABILITY OF MUNICIPAL WASTE LANDFILL LEACHATE IN A SBR AND BY COAGULATION-FLOCCULATION ON A BENCH SCALE
Abstract This article describes bench scale sequential, biological and coagulation-flocculation treatment of mature leachate for the removal of nitrogen and biodegradable and recalcitrant carbonaceous material. The biological stage was conducted on two SBRs, one of which inoculated with nitrifying sludge, another without an inoculum, for 152 and 133 days, re

2. Nitrogen removal from landfill leachate via the nitrite route
The feasibility of removing nitrogen from mature landfill leachate using the nitrite route was investigated in a two-stage SBR system - (1º first stage, short-cut nitrification; second stage, denitrification via nitrite. With a volumetric exchange rate (n) of 0.3 d-1 and an oxygen concentration of between 1.2 and 1.3 mg/L, the nitrite accumulation ratio - (

3. Statistical evaluation of mature landfill leachate treatment by homogeneous catalytic ozonation
This study presents the results of a mature landfill leachate treated by a homogeneous catalytic ozonation process with ions Fe2+ and Fe3+ at acidic pH. Quality assessments were performed using Taguchi's method (L8 design). Strong synergism was observed statistically between molecular ozone and ferric ions, pointing to their catalytic effect on •OH generat

4. Ozonização catalítica do chorume proveniente do antigo aterro controlado da cidade de Guaratinguetá-SP utilizando os íons Fe2+, Fe3+, Zn2+, Mn2+, Ni2+ e Cr3+ / Homogeneous catalytic ozonation of leachate from Guaratinguetá - SP landfill, using the ions Fe2+, Fe3+, Zn2+, Mn2+, Ni2+ e Cr3+
Durante anos, o lixo da cidade de Guaratinguetá foi aterrado e o seu produto recalcitrante não passou por nenhum tratamento físico ou mesmo químico, percolando diretamente sob o aterro. Mesmo tendo sido desativado e transformado em Parque Ecológico, o material depositado no local ao longo dos anos, continuará a ser decomposto por microrganismos e conti
