Highlights

  • Landfill leachate is the aqueous effluent generated as a consequence of rainwater percolation through waste [1]

  • The overall BOD5 and COD removal efficiencies were 88.2±5.7% and 84.2±9.6%, respectively. These results provide the evidence that both biodegradation and adsorption could effectively take place [17]

  • dewatered alum sludge (DAS), washed quarry dust (WQD), washed sea sand (WSS), red soil (RS), bio char (BC) and saw dust (SD) in mixedmedia Permeable Reactive Barrier (PRB) system have potential to treat organic, nitrogenous and phosphorus compounds of groundwater contaminated by landfill-leachate

Summary

Introduction

Landfill leachate is the aqueous effluent generated as a consequence of rainwater percolation through waste [1]. This leachate consists of a variety of contaminants in the form of organic and inorganic compounds which can be hazardous [2]. Organic compounds such as phenols, esters, ethanes, propanes etc. At present, when leachate has become the dominant groundwater pollutant and when safe groundwater is threatened, it is a timely need to investigate remediation techniques to treat contaminated groundwater. It is quite essential that such techniques are economical and practically feasible when their application is considered
