P&P WET ELECTROSTATIC PRECIPITATOR (WESP) - EXPERIENCE ADVANTAGES
We produce electrostatic precipitators, and we offer both wet electrostatic precipitators and dry electrostatic precipitators. In most cases, however, the wet electrostatic precipitator is the superior process as it allows the removal of submicron particles.
Dry electrostatic precipitators are only used for very large volume gas flows or high gas temperatures if the requirements for particle separation are not particularly high. Therefore, we describe the wet electrostatic precipitator in more detail below. If you have any questions regarding dry electrostatic precipitators, please do not hesitate to contact us directly.
"Protecting our environment and maintaining sustainable productions is paramount for industries and communities alike. We all must ensure that emissions released into our atmosphere do not cause any harm."
The reduction of emissions is not only essential, but also the continuous tightening of legal limits requires better solutions than ever before.
P&P – Wet Electrostatic Precipitators offer extraordinarily efficient control of submicron particles, aerosols, acid mists, heavy metals, condensed metal fumes, organics and many more.
Look inside a WESP and see that polluted air is made particle-free within seconds.

WET ELECTROSTATIC PRECIPITATOR (WESP) – OPERATING PRINCIPLE - HOW IT WORKS
Polluted gas enters the P&P - WESP. An electric field charges the particles in the gas by applying a high voltage between a negative electrode and the grounded collection electrode.
No barriers are restricting the gas flow resulting in a very low pressure drop.
The basic function principle of an electrostatic precipitator can be broken down to the following steps:
Step 1: The release of a negative electrical charge (electrons) from the discharge electrode is ionizing neutral gas molecules.
Step 2: The ionized gas molecules are now charging the dust particles
Step 3: The negatively charged dust particles are now drawn to the grounded surface of the collecting electrode.
The dust layer grows on the collecting electrode and in the case of a wet electrostatic precipitator, it automatically drips into the conditioning section and is drained.
Clean gas leaves the P&P – WESP.
- State of the art removal of submicron particles
Our P&P WESP is filtering submicron particles (size < 0.1 μm) better than any other filter system.
- High particulate collection efficiency of more than 99.9%
Resulting in exceptionally low emissions.
Therefore no additional fans necessary resulting in noise-free operation.
The P&P design allows for lower energy consumption than conventional wet precipitator systems.
Advanced modular design reduces erection time.
- Outstanding availability & reliability
We use exceptionally durable high-speed automatic voltage control systems.
- Minimum maintenance during operation
The process does not consume our specially designed electrodes. Only annual inspection is required, resulting in a low OPEX.
