    Abstract
    This research addressed the role of ozone and peroxone (ozone plus hydrogen peroxide) in particle destabilization, microflocculation, and as a coagulation aid at a pilot scale water treatment facility for Colorado River Water and State Project Water. Different treatment scenarios included: (i) alum, (ii) ozone/peroxone with alum, and (iii) ozone/peroxone with ferrous sulfate. While particle destabilization was observed at all dosages of ozone and peroxone, microflocculation was observed only at lower ozone dosages and the peroxone treatments. Ozone/peroxone plus alum treatments gave improved flocculation and overall filtered water quality. Pre-oxidation with 2.5 mg/L of ozone reduces alum requirements by 50 percent. Overall, in terms of particle destabilization and microflocculation and as a coagulation aid, peroxone performed better than ozone. FeSO4 appeared to be a more effective flocculant that alum.
