A method was devised to measure streaming currents developed when filtering tap water through a pilot rapid sand filter. From the streaming current data, the zeta potential of the filter media was calculated. The zeta potential value obtained is in line with other reported work. It is now possible to study what role the filter media surface potential plays in filtration.
