چکیده مقاله
Biological treatment of leachate In Malaysia is not well established and some of the important data for the treatment process still lacking The behavior of microbes is unknown for semi aerobic leachate treatment This research was consucted to establish some of the important data the biological treatment of semi aerobic leachate with and without the influence of powdered Activated Carbon PAC For the present study, semi aerobic leachate was collected from pulau Burung Landfill site PBLS , Nibong Table, penang , Malaysia The experiment involved operating two 16 L Continuous Flow laboratory – scale activated sludge reactors in parallel at room temperature and adjusted to pH=5 0 5 One of the reactors was supplemented with PAC of 75 150 m size to observe its effect on leachate the study was conducted with three different Hydraulic Retention time HRT and four different Dilution Factors DF base on initial Iron Fe concentrations the results indicated that 70% of Fe can be removed from the leachate at HRT 0 92 day DF=1 in the PAC reactor as compared to 30% removal without the presence of PAC In addition, the result suggested that, the addition of PAC could have detrimental effect on treatment dfficiency because of the adsorption of accumulated toxin compounds during shock loading the results showed enhanced reactor performance due to PAC addition in the Fe removal
