Sulfur dioxide (SO 2 ) is basically resulted from emission of fossil fuel. The ammonia washing is of methods used to remove SO 2 from fuel gas. Several wastewaters contain high ammonia concentrations causing the various problems at wastewater treatment or receiving environment. The synthetic wastewater containing NH 3 was sprayed down as flue gas moved up in the scrubber so that it could be a reaction between SO 2 and NH 3 . The effect of NH 3 concentration and pH on SO 2 removal was determined. SO 2 was decreased from about 1,000 to 0, 36, 49 and 66 ppm at NH 3 concentrations of 328, 88, 32 and 9 mg l −1 , respectively. While SO 2 of 1,000 ppm was completely treated at 328 mg NH 3 l −1 , pH was around 7.16 at the end of process. Consequently, it was recognized that this process could be used for both the SO 2 removal and the wastewater neutralization.
