A system for the electrical agglomeration of particles in a fluid using a plurality of electrically charged panels, such as electrets, metal panels, or any conductive material, positioned in series perpendicular to the direction of flow of fluid. The panels are about 20% to 80% open to the flow of fluid. The panels produce agglomerates of increasing size and number from the particles in a fluid as the fluid flows through each of the panels. The panels have an electrical charge of about 5,000 to 12,000 volts with amperage about 0.001 amps to 100 amps. Agglomerates are trapped by downstream capture media.
