| Abstract |
| In order to remove ethylene glycol(EG) in the pretreated polyester weight loss wastewater, calcium hydroxide was used as neutralization agent and immobilization media for the batch and continuous experiments. The TCODMn concentrations in the treated wastewater using culture of immobilization and suspension for the synthetic wastewater were found as 650 mg/L and 1,250 mg/L, respectively after 48 hours of reaction time. SVI(Sludge Volume Index) and TCODMn concentration were 74 and 73 mg/L at optimum F/M ratio, 1.32 kg-TCODMn/d·kg-MLVSS. The TCODMn concentration and removal efficiency were 213 mg/L and 93.5% by continuous experiments in the air-lift reactor. The TCODMn concentration was 82 mg/L, and the MLVSS concentration was 2,550 mg/L, when the volumetric loading rate was 3.04 kg-TCODMn/㎥·day for pretreated polyester weight loss wastewater. |
