Treatment of Landfill Leachate Using Ganoderma Australe Mycelia Immobilized on Ecomat

Abstract—Biological processes have been proven to be
efficient in treating landfill leachates. In this study, treatment of
landfill leachate by Ecomat-immobilized mycelia of Ganoderma
australe packed in a column was investigated. Continuous
recycling of leachate at a constant flow (20 ml/min) was
operated for 10 cycles to facilitate biological reactions. Diluted
leachate (50%) and raw leachate (100%) were tested for
comparison of efficiency of treatment. The results showed that
biological oxygen demand (BOD5) was not removed for diluted
leachate and a slight removal of 0.14 and 1.72% for raw
leachate after cycles 4 and 10, respectively. Chemical oxygen
demand (COD) removal occurred after each cycle with diluted
leachate demonstrating higher removal compared to raw
leachate. The highest percentage of COD removal of 51.62% for
diluted leachate and 22.79% for raw leachate were achieved
after the tenth cycle. Ecomat-immobilized mycelium of
Ganoderma australe could also reduce ammoniacal nitrogen
(NH3-N) exhibiting highest reduction of 45.95% and 30.90%
after cycle 8 for diluted and raw leachate, respectively. These
findings suggested that a white rot fungus, G. australe has the
ability to be considered as potential candidate in landfill
leachate treatment.
