Nitrogen Removal from Landfill Leachate by Microalgae
Landfill leachates result from the degradation of solid residues in sanitary landfills, thus presenting a high variability in terms of composition. Normally, these effluents are characterized by high ammoniacal-nitrogen (N-NH₄⁺) concentrations, high chemical oxygen demands and low phosphorus concentrations. The development of effective treatment strategies becomes difficult, posing a serious pr...
متن کاملNitrogen 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 – (1 first stage, short-cut nitrification; second stage, denitrification via nitrite. With a volumetric exchange rate (n) of 0.3 d and an oxygen concentration of between 1.2 and 1.3 mg/L, the nitrite accumulation ratio – (NO2-N)×100/(NOx-N)% – was between 32% and...
متن کاملNitrogen recovery from a stabilized municipal landfill leachate.
The present paper reports the results of an investigation aimed at evaluating the effectiveness of magnesium ammonium phosphate precipitation (MAP), commonly called struvite, for removing ammonia from a mature municipal landfill leachate. MAP precipitation was carried out at laboratory scale by adding phosphoric acid and magnesium oxide as external sources of phosphorus and magnesium, respectiv...
متن کاملleachate collection system/or municipal solid waste sanitary landfill (case study: babol sanitary landfill)
landfilling is an ultimate fate of any municipal solid waste management system, and it is a no alternative choice for disposal of municipal solid waste. the major environmental concerns associated with landfilling of wastes are related to the leachate generation and eventual discharge of leachate into the environment. leachate quality is formed due to aerobic and anaerobic processes taking plac...
متن کاملRemoval of COD and Colour from Sanitary Landfill Leachate by using Coagulation
This study investigated two methods for the removal of COD and colour from sanitary landfill leachates. The first method involved the use of coagulation/flocculation process using FeCl3 as a conventional coagulant and Ca(OH)2 as base-precipitant. The second method involved integration of Fenton’s reagent into the coagulation/flocculation process. Concentration of FeCl3 that reduced chemical oxy...
