Sorption and inhibitory effect of octylphenol ethoxylate Triton X-100 on methanogenic and denitrifying granular sludges.

The aims of this work were to characterize the sorption and evaluate the inhibitory effect of octylphenol ethoxylate Triton X-100 (OPEOTx) on methanogenic and denitrifying sludges. According to Langmuir isotherm, maximums OPEOTx sorption values on methanogenic and denitrifying sludges were 60.70 mg (gVSS) and 87.
