NOVELTY - Method for performing catalytic ozonation process, involves (a) heating 2-10 %mass graphene and activated carbon at 170-180 degrees C using polyvinyl alcohol as a binder to obtain graphene-activated carbon composite catalyst, (a) adding 1-3 mg/l or 0.05-0.2 l/minute ozone to solution comprising bromide ion and organic material, adding 50-100 mg/l catalyst obtained in step (a), controlling pH to 4-8.8, where organic material is degraded and formation of bromate is inhibited. USE - The method is useful for performing catalytic ozonation process (claimed) which is used in drinking water purification techniques. ADVANTAGE - The method is simple, inhibits formation of bromate and removes organic matter in water.
