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.
