摘要: The fate and behaviour of WO3 TiO2 mixture were investigated following the Organisation for Economic Co-operation Development 303A guidelines. nanoparticles found not to influence chemical oxygen demand removal efficiency which was maintained >80% hence activated sludge process on affected. eliminated from wastewater with a greater percentage 99.8% 95.5% in sludge. also had no effect polymorphs as X-ray diffraction revealed presence monoclinic anatase spiked into influent. mainly removed by bio-adsorption surface. total plate count that bacterial colonies present control test units comparable during gradual introduction chambers. biomass >0.75 MLVSS/MLSS (mixed liquor volatile suspended solids/mixed solids) both aeration vessels thus proportion microorganisms. A Ti W effluent due adsorbed solids only 3.6% 28.6% dissolution nanoparticles.
