Precipitation, Adsorption and Inhibitory Effects of Nano Copper in Activated Sludge
The use of manufactured nanomaterial is becoming more common is everyday products but the effect of such particles can have after the use of the products is largely unknown. In this study, removal and toxicity of nanoparticles and copper ions in activated sludge biomass were studied using copper nanoparticles in bench scale studies. Copper nanoparticles were removed more effectively (∼ 95%) than copper ions (30 – 70%) from the wastewater. Most Probable Number (MPN) test indicated that copper nanoparticles showed no inhibitory effects while 10 mg/l of copper ion were toxic to both coliform and ammonia oxidizing bacteria in the wastewater. The toxicity of copper to activated sludge microorganisms appear to depend on the concentration of (nano or ionic) copper in suspension.
