Biodegradation of 4-CP in an activated sludge reactor: effects of biosurfactant and the sludge age.


The biosurfactant's effect on the biodegradation of 4-chlorophenol (4-CP) in the existence of glucose was researched under the circumstances of using unacclimated culture and various sludge ages. The removal efficiencies of chemical oxygen demand (COD) and 4-CP, the growth of biomass and specific substrate removal rates were examined under various operating… (More)
