Sulfur dioxide (SO₂) is basically resulted from emission of fossil fuel. The ammonia washing is of methods used to remove SO₂ from fuel gas. Several wastewaters contain high ammonia concentrations causing the various problems at wastewater treatment or receiving environment. The synthetic wastewater containing NH₃ was sprayed down as flue gas moved up in the scrubber so that it could be a reaction between SO₂ and NH₃. The effect of NH₃ concentration and pH on SO₂ removal was determined. SO₂ was decreased from about 1,000 to 0, 36, 49 and 66 ppm at NH₃ concentrations of 328, 88, 32 and 9 mg l⁻¹, respectively. While SO₂ of 1,000 ppm was completely treated at 328 mg NH₃ 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 SO₂ removal and the wastewater neutralization.
