Effectively removes harmful pollutants from exhaust gas.
Simple design, easy to operate and maintain.
Low investment and operating cost.
Flexible application for various types of exhaust gases.
| 1. Exhaust gas inlet: | Exhaust gas is introduced from the bottom of the tower. | 
| 2. Absorption liquid spraying: | The liquid (water, alkali, or suitable chemicals) is sprayed from the top, flowing countercurrent to the gas stream. | 
| 3. Contact and absorption: | As the exhaust gas passes through the contact zone with the liquid, pollutants are captured by the liquid and separated from the gas stream. | 
| 4. Separation and collection: | The treated gas is discharged in compliance with QCVN 19:2024/BTNMT, while the liquid containing pollutants (residues) is collected and treated separately. |
