Operation mode of a venturi scrubber: The venturi effect consists in decreasing the section in order to increase the solubilisation of the pollutant in the scrubbing liquid.
Once the pollutants are solubilised, they will be degraded and neutralized inside le liquid by some chemical products (reagents). The scrubbing liquid will be emptied periodically, send to the water treatment plant.
The scrubber can be realized in PPH or HDPE. The diameter of the scrubber, the decreasing diameter will be design regarding the temperature of the gas, the type of pollutants and the airflow to treat.
Some venturi scrubbers are creating a depression; the scrubbing liquid gives a pressure loss replacing the fan in the installation.
