Application of A New Technology For Dairy Processing Wastewater Treatment Using ActivatedSludge

摘要

Background: Dairy wastewater contains high levels of organics and other pollutants. Objective: The present study wascarried out to study the treatment process of dairy effluents using activated sludge process (APS) without and withNanoparticles using a bench scale model. The model consisted of aeration and sedimentation tanks. Samples were collectedfrom El-Masreyeen factory in 6th October City from the ground tank of compact unit, Egypt. Results: The results proved theability of the APS system without nanoparticles for the treatment of dairy wastewater. After the addition of nanoparticles, thetreatment efficiency of dairy wastewater increased significantly. Conclusion: Addition of Nanoparticles to activated sludgeimproved the overall removal percent for all measured parameters to more than 90%. The application of nanoparticlesproved as a clean, environment friendly and cheap technology to improve the treatment of dairy wastewater using ASPsystem.
