Influence of Coagulant Species on Sulfur Oxide (SOx) Emission from the Textile Sewage Sludge Combustion

Ari Rahman, Naoyuki Kishimoto, and Takeo Urabe
Abstract—Simulation of textile sewage sludge combustion to investigate the typical flue gas generation was carried out by Material-oriented Little Thermodynamic (MALT) software simulation. Textile sewage sludge was modeled on the basis of loadings of effluents, daily usage of dyeing material, heavy chemical for wastewater treatment and daily production of activated sludge. Combustion temperature was set in the range of 500 °C to 1100 °C. In this research the influence of coagulant species used in wastewater treatment on flue gas especially on sulfur oxide (SOx) generation was investigated. The replacement of conventional coagulant FeSO4 and Al2(SO4)3 to FeCl3 gave the result of more than 18% reduction of SOx at the combustion temperature of 850 °C and 19% at the temperature not less than 950 °C. The distribution ratio of sulfur element indicated that SOx especially in the form of SO2 was generated at the combustion temperature of 700 °C and the concentration increased with a rise in combustion temperature.

Index Terms—Textile sewage sludge, coagulant, sulfur oxide (SOx), MALT.
