Heavy Metals Monitoring in Leachate from Landfill Site of Qazvin, Iran
Background & Aims of the Study: Leachate production is a major problem for solid waste landfills and causes important threat to health public and environment. One of the typical properties of heavy metals is that they cannot easily decompose in the environment. The aim of this study was to measure of heavy metals concentrations in old-age leachate from Qazvin landfill site, Ira...

aims: municipal landfill leachate contains high concentrations of heavy metals, organics, ammonia . t he efficeincy of electrochemically removal of heavy metals from landfill leachate was studied. materials & methods: the leachate was obtained from kahrizak landfill in south of tehran. the experiments were carried out by batch process. the 2liter batch reactor was made of glass. there were eigh...
متن کاملNitrogen 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 کاملUnderstanding Integrated Removal of Heavy Metals, Organic Matter and Nitrogen in a Constructed Wetland System Receiving Simulated Landfill Leachate
This study investigated the integrated removal of heavy metals, organic matter and nitrogen from landfill leachate using a novel laboratory scale constructed wetland system. The main objectives of this study were: (i) to assess the overall effectiveness of the constructed wetland system for treating landfill leachate; (ii) to examine the interactions and impact of key leachate constituents (hea...
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...
