Why use ultrafiltration system in electrophoretic coating process ?

electrophoretic painting

Ultrafiltration system of Electrophoresis coating process of the main purpose is to enable the E COAT aluminium is a closed-loop system,  reducing emissions of pollutants, and can also save the electrophoresis coating material. The workpiece after electrophoresis with very low electrical conductivity of water washing, it can reduce the formation of two marks, particles of film defects electrophoresis film. But with the pure water flushing, would lead to flushing water consumption, and rinse water contains a lot of electrophoretic coating, direct emission is not only a waste of paint and pollution of the environment, increase the cost of sewage treatment. The biological membrane filtration water rinse water, filtering out of the coating into the electrophoresis tank is used to filter out of the water, and is called the ultra filter, can be used to rinse again workpiece. if In automobile industry, this process is called UF washing (that is, the ultrafiltrate washing process).
