Abstract
Bioreactor landfill could be considered among the low-cost technologies to deal with waste. Even though it has many advantages, challenges remain, including the persistence of NH3-N in the leachate. A total of 28 bacteria were isolated from landfill leachate samples of Batu 55, Maran, and Jengka 10, Maran, and screened for their potential to remove ammonia nitrogen (NH3-N) and nitrate (NO3 −). One of the predominant removal reducer was identified as Pseudomonas sp. using macroscopic and microscopic observation and simple biochemical tests. Flask shake studies using leachate with COD/N ratio between 7.0 and 10.0 showed that nitrate and ammonia could be removed up to 30 % and 40 % using this Pseudomonas sp. Pseudomonas sp. also shows the capability in removing organic matters measured in terms of COD and BOD5 values up to 60 %. This work showed that our local isolate has the potential to reduce ammonia and COD during leachate treatment.
