The development of industry should be oriented to an environmental friendly industry. The existing industrial waste must meet goverment standard. The most commonly applied biological waste water is the actived sludge process. This system produces biosludge as waste that must be separated from waste treatment process. One alternative re-utilization of biosludge is by reusing it an adsorbent through pyrolysis.<p> <br /> <br /> <br /> The purpose of this research is to test the optimum condition of pyrolysis and the optimum concentration of activation agent that is used to produce adsorbent from biosludge. The optimum condition of pyrolysis was reported to be 800 degrees C, for 60 minutes, and using 5 M at activation agent (ZnCl2) (Supriyadi, 2006). The source of biosludge was varied. The performance of biosludge after pyrolisis or adsorbent was then examined to phenol.<p> <br /> <br /> <br /> Research results show that adsorbent from a mixture from three WWTP (Waste Water Treatment Process) Biosludge I, II, and III has good phenols adsorpsion ability. With Langmuir isotermal adsorption model, the adsorbent has qm constant (maximum adsorption capacity of 68.49 mg adsorbate/g adsorbent, that is higher than the previously reported value (Supriyadi,2006) of 34.36 mg/g.
