Cod And Sulfide Removal Efficiency At Different Mlss Concentration In the present study, the influent cod and sulfide concentration of the spent caustic wastewater entering the becc was set to be at 700 mg l and 85 µg l respectively and the removal efficiencies. However, in contrast with the cod removal efficiency, sulfide removal efficiency was increased with increasing mlss concentration. this result might be due to the presence of sulfur oxidizing bacteria in the bioreactor that were functioning effectively and able to degrade the sulfur content in the influent wastewater.
Cod Removal Versus Different Aeration Time Under Different Download scientific diagram | performance of cod removal on mlss concentration. from publication: assessment of membrane bioreactor in treating spent sulfidic caustic wastewater: effects of. The effect of concentration of mlss on cod removal are shown in fig. 2. a mlss concentration of 2 g l was not very effective because there were not enough microorganisms present to biodegrade all the organic matter in the influent wastewater. increasing mlss from 2 to 3 g l improved the removal efficiency for cod from 89.1% to 92.8%. Mlss operated the higher removal efficiencies of cod achieved. the increase in cod removal efficiency could be attributed to a large number of microorganisms in the higher sludge concentrations. the time courses of nh 4 n and tn concentrations and removal efficiencies under different mlss in three reactors are shown in figure 2. the average.

Furthermore, it was concluded that mlss concentration below 3000 mgtss l does not have significant effect on a stage performance. above this range, the high mlss concentration amplified the effect of the poor settling performance of the sludge either due to pin floc settling or high svi 30. as a result, limited pcod removal and cod redirection. The cod removal efficiency was not significantly different between the two olrs of 0.86 and 1.8 kg cod m 3 d, but it was significantly affected at an olr of 3.7 kg cod m 3 d. table 2 impact of olr.
