Abstract (en)

[origin: WO9936150A2] A vibratory separation system has a drive mechanism for imparting a vibratory motion to a membrane module to enhance filtration. The membrane module comprises one or more filter elements arranged in a stack, each filter element having a separation medium. The vibratory motion imparted to the membrane module generates a dynamic flow boundary layer at the separation media. This fluid shear boundary layer, in turn, generates lift, thereby inhibiting fouling of the separation media.
