What Is The Difference Between Dead-End Filtration And Cross-Flow Filtration?

Ceramic membrane manufactured by JIUWU HI-TECH is used for liquids separation in a cross-flow filtration way which is different from dead-end filtration.

Dead-end filtration means the fluids flow is vertical to the filter surface, and the retained particles rapidly solidify on the surface of the filter to form a so-called filter cake. The pores of the filter are clogged by the filter cake, and the filtration performance is greatly reduced in a short period of time.

Cross-flow filtration means turbulence will happen on the surface of the membrane. Therefore, it allows the filtered material to form a filter cake on the filtering surface and keep the flow constant.
