Sanitary landfilling is an important alternative way for disposal of municipal solid waste (MSW) in some developed countries
and developing countries in general, owing to its economic accessibility. On the other hand, landfilling is a matter of concern
due to generation of heavily polluted leachate. Landfill leachate, especially old leachate, becomes more refractory with time and
is very difficult to treat using conventional biological processes. To this end, aged refuse (the reclaimed material from sanitary
landfilling) based bioreactor/biofilter (ARB) has proven to be a promising alternative for the removal of various pollutants from
landfill leachate these years. This presentation gives an overview of various types of ARBs used (like single-stage, two-stage
and three-stage or aerobic, semi aerobic or anaerobic) and the performance of the ARB under the different environmental and
operational factors like temperature, organic loading rates, hydraulic retention times etc., and their efficiencies in eliminating
high concentrations of various pollutants from the leachate as well as the pollutant removal mechanism of different ARB.
Finally, the future research highlights are also prospected.
