✦ Synopsis

We studied how to increase the filtration flux from three viewpoints: promotion of turbulent flow in raw water, coagulation effect and membrane backwashing. As a result, we found that intermittent membrane backwashing combined with turbulent flow promotion is an effective means to maintain high filtration flux of the membrane module.
