Filtrating process is used widely in water treatment.Deep bed filtrating effect is influenced by surface potential of filter media greatly.Quartz sand has a much negative surface potential which impact on its effect.The contrasts of surface potentials and filtrating effect of quartz sand,iron oxide coated sand and compound coated sand show that the compound coated sand has a steady and favorable filtrating effect attribute to its near neutral surface potential.
Key words： filtration; coated sand; surface potential
