This paper presents experimental results of the performance of an electrostatic liquid filter model that utilizes an a.c. electric field to accelerate the coagulation of contaminant particles. The filter model consists of the coagulating cell for coagulating the particles and the collector for capturing coagulated particles. The coagulating cell involves parallel electrodes and spacers inserted at the middle of the electrodes to increase the magnitude of the velocity gradient. The collector is made of a metal mesh and an electrode pair; the mesh is arranged perpendicularly to the flow and in parallel with electric field. The effects of the electric field strengths in the coagulating cell and the collector and of the mean flow velocity are investigated. The effects of the type of electric field, a.c. or d.c., in the collector and of the mesh size are investigated as well. Useful data to develop a high-performance electrostatic filter are obtained.
