Influence of cerium oxide nanoparticles on dairy effluent nitrate and phosphate bioremediation.

This study investigated, for the first time, the role of cerium oxide nanoparticles (CeO NPs) on dairy effluent nitrate and phosphate bioremediation using different inoculum sources. Two inoculum sources (wastewater and sludge) were obtained from the dairy wastewater treatment plant unit. A culture was prepared to be tested in the treatment of nitrate and phosphate effluent, and the role of CeO NPs was checked to be completely efficient after 5 days of incubation.
