Abstract

The removal properties of Polyethylene glycols (PEGs) known as the important group of synthetic polymers of ethylene oxide were examined by the bio-reactor equipped with a mesh filter module. PEG-1000 and PEG-2000 were fairly removed on the basis of TOC, which were 75.1% and 51.6%, respectively. In the case of PEG-20000, the removal efficiency of TOC was less than 15.2% and the favorable acclimation of microbes was not obtained. It was suggested that this system could effectively maintain microbes for the biodegradation of low molecular weight of PEG and TOC removal was significantly influenced by PEG molecular weight.
