The dark brown color and high turbidity of monosodium glutamate (MSG) manufacturing wastewater needs to be treated first to avoid harmful effects on the environment and human health when disposed. Electroflocculation in a batch system was used to remove its total suspended solids (TSS) and color. Removal efficiencies of TSS and color at different operating temperature were measured for the evaluation of the treatment. Temperature and pH which are the secondary effects were also measured. It was found out that increasing the amount of current supplied to the system would result to a higher removal efficiency and faster rate of removing the pollutants. At the end of the 3-hr electroflocculation at 6 A, 95.2% of the TSS and 91.47% of the color were removed. The temperature had risen to 74 °C and the pH became neutral from 4.05 to 7.3. The general factorial design showed that the effect of operating current on the TSS and color removal is significant. It also showed that charge dose is the same for any amount of current supplied. The charge dose computed was 22.2231 C/mg pollutant removed which requires an energy ranging from 5.8 x 10⁻⁵ to 7.96 x 10⁻⁵ kWh/mg pollutant removed. The electroflocculation of MSG manufacturing wastewater has a maximum energy cost of 1874.44 PhP/m³.
