Decolorization of Reactive Brilliant Red X-3B Simulated Dye Water by Novel Coagulants
Five novel coagulants,DC-491,Fennofix K97,BWD-01,MD-03 and MD-04 were chosen to treat reactive brilliant red X-3B simulated wastewater by jar tests.The results showed that the decolorization efficiencies were all higher than 75% at initial pH 8.2 and temperature 20℃ after 20 minutes of reaction.Then,two typical coagulants,BWD-01 and MD-04 which had better performance were chosen to study the effect of dye removal of X-3B at different operating parameters,including coagulant dosage,pH,sedimentaion time and reaction temperature of simulated wastewater.Decolorization efficiency of MD-04 for X-3B solution was higher than 80% in pH range from 3 to 9,while for BWD-01,efficiency increased from 37.3% to 82.3% in this pH range.For both BWD-01 and MD-04,the color removal efficiency increased as the solution temperature increased and the maximum efficiency was over 94% at 40℃.Small changes in the color removal efficiency were observed after 1 hour sedimentation for both coagulants.
