Effects of adding wash tower effluent to Ano Liossia landfill to enhance bioreaction c by Olympia Galenianou.

A theoretical study was performed on the effects of adding sulfate-rich wash tower effluent from the Athens hospital waste incinerator to the Ano Liossia landfill of Athens. The method of mass balance was used to examine the production of leachate, the generation of methane, and the reduction of sulfates into sulfides. The water mass balance was performed using the method of Thornthwaite and the result indicated that the leachate collection facility at Ano Liossia landfill would be able to handle the additional leachate. The hydrocarbon-methane mass balance was performed using the EPA's LandGEM model which is based on first-order decomposition of the waste. A 26% difference between the generation of methane in a conventional landfill and a bioreactor landfill was predicted. Finally, a first-order model was developed by analogy to the LandGEM model to study the reduction reaction of sulfates into sulfides. The amount of hydrogen sulfide produced from solid waste disposed in the landfill dominated the amount of hydrogen sulfide produced from the additional wastewater.
