Abstract

This research investigates the performance of Moving Bed Biological Reactor (MBBR) for treatment of Textile of wastewater. For this purpose a MBBR reactor was used, fed with synthetic wastewater which was a combination of molasses, urea, salts of buffer phosphate and various concentrations of different days.After starting up the reactor by synthetic wastewater with a COD concentration of 1000 mg/L and adjustment of microorganisms according to the existing condition, wastewater with dye concentrations of 1, 10, 15 mg/L at certain periods of time, was added to the reactor. Under the conditions of 23-28oc and hydraulic retention time of 24 ht and, COD concentration of 1000 mg/lit, COD removal efficiency was 68.5%, 89.15%, 90.46% respectively. The COLOR REMOVAL was 61.56%, 75.85%, 80.05% accordingly, which showed an increase in COD and COLOR REMOVAL efficiency by increasing the color concentration.By feeding the reactor with a COD of 2000 mg/L with color concentration of 15 and 25 mg/L, the COD removal efficiency was 91.78% and 79.50 respectively. Under these conditions the percentage of COLOR REMOVAL was 79.7% and 64.21%, respectively. It is concluded that a decrease in COD and COLOR REMOVAL efficiency with increasing the COD load is attained. Moreover according to the results, it was observed that under constant concentration of dye, by increasing COD from 1000 to 2000 mg/L, efficiency in substrate and organic removal does not change.The obtained results in this study state that MBBR reactor can be used for removing organics and color in treatment of textile of wastewater.
