Is it better to circulate electrophoresis tank fluid in the forward or reverse direction?

Nippon Atmos has the proprietary technology of reverse circulation of electrophoresis tank, which is different from the original traditional way of circulation of electrophoresis tank liquid in that it flows in the reverse direction, the surface flow rate is relatively increased, and overflow tanks are set up at both ends of the electrophoresis tank. The new reverse circulation method greatly improves the quality of the electrophoretic coating, and reduces the particle-type pockmarks (especially those formed by iron powder) on the top cover of the body by more than 90%.
