Abstract
The permeation experiments were carried out to examine the separation characteristics of the modules which were piled up the disc-ring shape patterned membranes in this study. First of all, permeability of the pure water was measured for the self-made 5 shape disc filters, and varied from 0.25 to $2.24L/m^2{\cdot}hr{\cdot}bar$. The module showed the maximum pure water permeability was the maximum permeation flux, and the module showed the minimum pure water permeability was the minimum permeation flux for 0.1 wt% kaolin solution. However, all of the modules were not proportioned to the pure water permeability. Also, the backwashing was performed periodically for the module 1 in order to operate with 0.1 wt% kaolin solution for a long time. The most efficient operating condition was the 8 minute permeation and 2 minute backwashing cycle.
