Summary

When Zoogloea ramigera and its extracellular polymer were daily added to the laboratory scale activated sludge reactor treating tannery wastewater, more than 15% of the COD concentration (COD; 151 mg/l) and 32% of the turbidity (NTU; 9.2) were removed compared with a controlled reactor (COD; 336 mg/l, NTU; 43.5) operated without any additions.
