Abstract

Monosodium glutamate (MSG) wastewater is a very refractory case of high strength organic wastewater. To investigate the effect of operating variables on treatment of MSG wastewater, a laboratory scale study was conducted. The treatment of MSG wastewater was studied in a continuous flow anaerobic fluidized blanket (UASB) reactor. The effect of operating variables such as organic volumetric load rate (OLR), pH, volatile fatty acids (VFA) and alkalinity on efficiency of treatment and recovery of biogas was investigated. The results showed that the gas production rate was 3.02 8.83 kg COD / m³·d volume load, the gas production rate and COD load volume was positively related; as influent COD in range of 11878 16922 mg·l^-1, COD removal rate of effluent was in range of 57.00 79.63 %; UASB with high acid-base buffering capacity could deal with the acidic organic wastewater (pH<;3.5) without adjusting pH.
