| Abstract: | The separation of suspended solids from an activated sludge process was carried out in an electro-flotation cell that has two sets of electrodes,three Ti/RuO2-IrO2-TiO2 anodes and three Ti screen cathodes.The effect of hydraulic retention time(HRT) on the performance of the electro-flotation system was examined.The kinetics of flotation of suspended solids by electrolytically generated micro-bubbles was also studied and found to follow first order rate expression.Electro-flotation cell can accomplish high performance in solid-liquid separation application of this type. |
