How VSEP Works

Written on February 2, 2015

In the crudest sense Vibratory Shear Enhanced Processing (VSEP) takes the untreated feed water and separates it into clean water (also called permeate or filtrate) and dirty water (also called reject or concentrate), all without any chemical additives or pretreatment.

It works the same as many other filtration systems in that a pressure is used to force a fluid through a filter.  The filter catches the contaminants as the fluid passes through and the fluid downstream of the filter is clean, or at least “cleaner”.  Since the filter is collecting the contaminants it typically require routine cleaning or replacing, This is what differentiates the VSEP system.

The patented technology in the VSEP system is the use of vibrating membranes.  These membranes, which come in different varieties depending on the particle size to be filtered out, are where the filtration takes place.  An oscillation is introduced that prevents colloidal fouling, or basically the clogging up of gunk on the filter.  The introduced vibration achieves this by preventing the matter being filtered from the liquid from settling on the membrane and blocking the pores that allow the filtrate to pass through.

The vibration is introduced by a resonating spring drive system.  It works on the principle of a motor with an eccentric weight on its drive shaft that attached to the plate, causing the plate to shake.  The filter pack is attached to the same plate and the movement of the plate is transferred to the filter pack, causing the membrane to oscillate.
