Leachate is a liquid produced from the landfill that contains high concentration of heavy metals, chemicals and nutrient loading. The treatability of these contaminants are complicated since the current treatment technology are costly and site specific. Therefore, this study was conducted to evaluate the treatability of stabilized landfill leachate by using waste (pressmud ash) as an absorbent. The pressmud with 400^oC are highly potential material with a low cost which can be a good adsorbent substitute due to capability reducing efficiencies of physicochemical parameters in real wastewater leachate. Leachate samples were collected from municipal solid waste (MSW) Pulau Burung Sanitary Landfill (PBSL) and were analyzed for heavy metal, COD, pH, ammonia, colour. This research was performed in two phases i) leachate characteristic, ii) treatability assessment by using press mud ash. Press mud was sampled from the sugar mill, Malaysian Sugar Manufacturing (MSM) Sdn Bhd, Seberang Perai, Pulau Pinang. Pressmud ash was prepared by buring at different temperature from 100 to 700 degree celcius and test at 24 hours shaking time, pH 8, 4000 rpm.
