Effect of anaerobic sludge source and condition on biosorption of PCP

Biosorption isotherms for pentachlorophenol (PCP), on granular and dispersed anaerobic sludge from five different industrial sources fit well to the Freundlich equation. No significant difference was observed in biosorption capacity between dispersed and granular anaerobic sludge. Some variation in biosorption capacity was observed among the different industrial sources of sludge. Comparison with results reported by other investigators suggested that biosorption by anaerobic biomass is lower than that by aerobic microorganisms.
