The Benefits of VSEP

Written on February 2, 2015

There are a range of available separation technologies for separating liquid from both suspended solids and dissolved substances.  Some of the more common approaches include:

  • Centrifuges
  • Clarifiers
  • Evaporators
  • Rotary Drum Vacuum Filters
  • Pressure Filters

There is also a very cost effective alternative in the VSEP system.  VSEP offers the follwwing benefits:

1. High flux rates

In the separation of most products the VSEP’s rate averages ten time higher that of conventional separation technologies. The high flux rates from a VSEP means more throughput for your investment.

2. Fouling resistance

The patentend vibrating membane means less membrane replacement and less downtime for maintenance.

3. High Solids

Because VSEP does not depend on crossflow to create shear it can filter to a very high level of solids.  Achieving more solids in a single pass simplifies processing.

4. High Efficiency

VSEP has a useful energy conversion of 99%.  This is achieved through the ultra efficient resonating drive system that focuses the shear waves on the membranes themselves. Virtually all of the energy from the drive motor is dissipated as shear on the face of the membrane.  This lowers operating expenses

5. Engineering dependability

The engineering design of the VSEP with minimal moving parts means it is robust, eliminating costly downtime.

6. Compact Design

The compact design of a VSEP with its vertically oriented membrane stack requires 10 to 100 times less floor space t than conventional systems.  A single Series I system producing up to 750 litres per minute only needs two square meters of floor space.

7. Convenient Testing

Each VSEP system is tailored to the specific client application.  Data already exists for a wide variety of applications and where it does not then testing is performed to ensure the optimum performance of the VSEP.  Testing allows for the selection of the appropriate membrane type by determining the optimum membrane material and pore size.   Amplitude, temperature and pressure are also tuned to determine the optimum operating parameters.

8. Low Cost

The aforementioned beneits all equate to a lower overall cost.

  • high flux rates allow more throughput capacity
  • fouling resistance means less membrane replacement and less cleaning and maintenance
  • high solids in a single pass simplifies processing
  • high efficiency lowers operating expenses
  • engineered dependability eliminates costly downtime
  • compact design means savings on installation, space requirements and plant design
