SANI Membranes has developed a new and patented membrane filtration technology based on the Free Flow Plate™ modules and the Vibro™ technology.

The Vibro technology delivers efficient continuous micro- and ultrafiltration with less fouling, less energy consumption and a simple and sanitary design.

The Vibro technology is based on the cross flow filtration principle, but the turbulence at the membrane surface is here created by vibrating the membrane relative to the feed instead of applying a fast cross flow.

The turbulence is only produced at the membrane surface and the huge pressure loss from a traditional cross flow is eliminated. As a consequence the transmembrane pressure (TMP) becomes close to uniform throughout the system, making unique process control and sharper separations possible.

Cross Flow Filtration vs. Vibro™ Filtration

Fast flow creates turbulence and pressure loss

Circulation pump affects product and uses energy

Energy extensive cooling is needed

Vibration creates turbulence on surfaces

No pressure loss – uniform TMP

Turbulence only where needed! Minimal cooling needed

Vibro technology benefits

Vibro™ technology is a micro- and ultrafiltration solution with several benefits compared to traditional cross flow systems:

Ideal Separation

Vibro™ technology improves separation due to a sharper cut-off. Eliminating the cross flow pump leads to a system with minimal pressure loss. The result is a close to uniform TMP in the entire system securing a uniform cut-off over the entire membrane surface.

Unique Microfiltration

Vibro technology ensures the ability to run efficient microfiltration at extremely low TMP in the entire system (e.g. 0.10 bar). The low TMP reduces fouling and compaction and delivers continuous microfiltration with a super simple solution.

Less Energy

Vibro technology reduces the energy consumption by 50-95%. A cross flow system creates turbulence in the entire system whereas Vibro™ technology only creates turbulence on the membrane surface where it is needed to reduce fouling.

High Yield Recovery

The ability to run efficient microfiltration ensure a continuous high transmission of your target molecules leading to a yield increase of up to 25% compared to traditional technologies.

Eliminating manual work

With true continuous microfiltration you can replace costly and labor intensive single use filters. The Vibro systems can be automatically maintained by Cleaning In Place, an environmentally friendly solution requiring no manual labor.

High Concentration, Viscosity and Solid Loads

Vibro technology is ideal for membrane filtration of highly concentrated media due to the Free Flow Plate™ modules design with open free flow channels and no spacers.

Gentle Product handling

Vibro technology handles the product very gently as the elimination of the cross flow pump almost eliminates pump shear.

Higher Yield

The Free Flow Plate modules are fully drainable of both permeate and retentate – 100% of your product can be recovered.


Vibro technology sets a new sanitary standard with the open and clean design of the Free Flow Plate modules without spacers and flow dead areas. Fouling starts later on flat surfaces and is easier to remove when formed – reducing CIP time and chemical loads for cleaning.


The Vibro filter elements are equipped with organic membranes in the range from 1 kDa to 1 µm from well known industry suppliers.

Standard UF membranes are in the range from 1-800 kDa and are made in PES, PESH, PVDF & PAN.
Standard MF membranes are in the range of 0.08-1 µm and are made in PVDF & PTFE.
