Envibats Wet Electrostatic Precipitators (WESP) are robust and efficient. They are designed to work in various applications and to deliver air pollution control to the highest standards, with the industry's highest reliability. Our WESPs have a modular design, enabling us to adapt the number of modules to fit the capacity necessary for the WESP. For more information, contact us.

There are many reasons to choose our WESPs:

  • Lower emissions - particle concentrations below 1 mg/Nm3 can be achieved
  • High efficiency in removing sub-micron particles
  • Removes both aerosols and solid particles
  • No fire risk
  • Very low maintenance
  • High voltages can be achieved

How our Wet Electrostatic Precipitators work

The gas flows into the WESP from either the top or the bottom. Our highly efficient gas distribution system ensures an equal distribution across all of the vertical tubes. The walls of the tubes are electrically grounded and act as collector electrodes. An emission electrode is positioned in the center of each tube, to which a high voltage is applied. The gas closest to the emission electrode is ionised by a corona discharge, in turn giving aerosols and particles a negative charge and driving these towards the collection electrode. Particles adhere to the collector electrode, until they are washed off when the system is flushed.

Envibats emission electrodes have a unique and patented design which make our WESPs extremely efficient, while maintaining minimum maintenance.

Wet electrostatic precipitators can be used in a variety of applications. See our refences for examples of how a WESP can be used.
