Abstract

Coal combustion technology is an alternative to cut down emission level caused by combustion of energy. The use of coal will produce waste called bottom ash which may contain heavy metal and can cause hazard if being exposed to the acid rain. Acid rain directly can lead to groundwater pollution if the waste is being disposed directly into water bodies without adequate treatment to remove harmful compounds. Contaminated water by bottom ash is called leachate which can dissolve into ground water. Leaching test is conducted to produce leachate from bottom ash. Electro-precipitation process is a process to treat bottom ash by reducing heavy metals before being disposed. Through this process, about 4.5% of heavy metals leached from bottom ash after react to acid rain are determined. As the sample solution is more acidic (pH of 3.4), the amount of heavy metals leached are up to 6.9%. This indicated that electro-precipitation is the processes that can help in controlling bottom ash from pollute the groundwater.
