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 کاملEvaluation of Physicochemical Pretreatment Methods on COD and Ammonia Removal from Landfill Leachate
The goal of this experiment is to evaluate the effectiveness of different leachate pre-treatment options in terms of COD and ammonia removal. This research focused on the evaluation of physical-chemical methods for pre-treatment of leachate that would be effective and rapid in order to satisfy the requirements of the sewer discharge by-laws. The four pre-treatment options evaluated were: air st...
متن کاملPretreatment of ammonium removal from landfill leachate by chemical precipitation.
Chemical precipitation is a useful technology to remove ammonium (NH(4)(+)) from landfill leachate. In this paper, the removal of ammonium from landfill leachate was studied. The objective of this study was to investigate optimum pH, optimum molar ratio, and different kinds of chemicals combinations for magnesium ammonium phosphate (MAP) precipitation. Furthermore, the kinetics of MAP formation...
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...
