4.3.2.7 Increase in chloride concentration
Waste aeration causes the growth of chloride concentrations in leachate that were recircu-
lated through the waste layer. It was observed that Cl
−
concentrations in leachate began to
increase simultaneously with the rise of the pH value. It can be explained by the influence
of pH on chloride dissolution, which increases with the increase of pH (Biligili et al. 2006,
Sekman et al. 2011).
4.3.2.8 Reduction in leachate volume
Landfill conversion from anaerobic to aerobic leads to the reduction of leachate volumes,
greater than 80%, due to the intensive evaporation related to the ...
