This paper deals with an experimental investigation of the capture of contaminant particles onto the electrode surfaces of a d. c. type electrostatic liquid filter. Oils into which silica particles of 4 micrometer in diameter are mixed are used as the test liquids. The effects of some factors such as type of oil, electric field strength and flow velocity on the amount of particles captured on the electrodes or detached from them are investigated. The experiments show that the amount of the particles captured on the electrodes is strongly affected by the electrification characteristics of particles in oil and increases with the magnitude of electric charges on the particles and the electric field strength, but that it tends to be saturated at high electric field strengths. It is also shown that the relative hardness or easiness of the particle detachment resulting from flow resistance at null electric field is mainly determined by the electrification characteristics of electrode surface.
