Abstract
The present study was undertaken to investigate the characteristics of leachate generated from landfill lysimeters where coal fly ash is used as a cover layer. Three experimental conditions were tested in triplicate during 100 days using nine laboratory-scale landfill lysimeters. Lysimeters A were loaded purely with municipal solid waste (MSW) and considered as control treatments. Lysimeters B and C were filled with MSW and two different cover types, i.e. soil and coal fly ash, respectively. The cumulative quantity of the leachate generated from lysimeter using coal fly ash cover was found in 40.87% less than the lysimeter using soil cover and 56.53% less than the lysimeter filled solely with MSW. In addition, the lysimeter using coal fly ash cover generated the lesser values of BOD and COD, and concentrations of iron, manganese, lead, and total suspended solids (TSS), compared with the lysimeters using soil cover and control.
