If you wish to see how our media is different from that of other microfiltration companies,
please see here. This explains the true meaning of pore size in filters. A dedicated web site
provides details of the novel VibraFilter microfiltration process.
This pilot-scale VibraFilter uses gentle pulsation of the feed suspension and a spiral wound membrane. A small image is shown below.
For more details we suggest that you view the images and videos in the table, starting with the rig description shown in the first image (then video) and then work your way down through the table. You will need to use the browser back button to return to this table.
The Pilot-scale VibraFilter has a 0.1 m2 membrane area contained in a 2 inch pipe and is less than 10 inches in length. A 1 m2 membrane fits inside a 4 inch pipe and is less than 1 metre in length. The process and pilot-scale VibraFilters oscillate the feed suspension, whereas the laboratory VibraFilter uses an oscillating membrane. High permeate flux rates are achieved and low filtration pressures - see the high flux (3.0MB) video, and the rig description image.
