Abstract :
Leachate from transfer station requires treatment before being discharged into theenvironment to avoid surface and underground water contamination. Variousfactors such as waste composition, availability of oxygen and moisture, designingand controlling of transfer station operations have been shown to affect thecomposition of the leachate. The high COD, BOD, ammonia nitrogen (NH3-N)and heavy metals contents of fresh leachate are the main problems faced byleachate treatment operators. The result of the present study indicated that thisprocess reduced the COD content by 43%.The average removal efficiencies ofBOD5, TS, TSS, and VSS were 80, 49, 37 and 39 %, respectively.
