Bioremediation of Leachate in the Landfill Drainage System

Abstract

The paper describes a laboratory experiment on the biological activity of bacterial populations derived from landfill waste and established on granular materials under conditions similar to those in landfill drainage systems. A laboratmy column has been used to model that system. Artificially formulated leachate has been recycled through the column and t}Jg_ composition of the leachate, the gas produced and its content have been analysed. The results have shown that bacteria derived from landfill waste and established once on landfill drainage aggregate have the ability to survive at low levels of activity and rapidly revive after the addition ofnutrients. These results are of great significance when the potential use of landfill drainage systems for bioremediation of leachate is concerned.

Screening and selection of autochthonous fungi from leachate contaminated-soil for bioremediation of different types of leachate

“…Generally, the bioremediation is defined as a process that uses microorganisms or their enzymes to degrade the environmental contaminants into less toxic forms [19]. Currently, bacteria have been the most frequently used organisms in bioremediation applications [20,21]. They can play an important role in understanding the uptake and potential removal behavior of heavy metals [22].…”
