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
