GAS WASHER (SCRUBBER)

Scrubber systems are a group of control devices used to remove and neutralize some particles or gases from industrial systems or wastewater treatment plants.

Scrubber systems are a group of control devices used to remove and neutralize some particles or gases from industrial systems or wastewater treatment plants.

Usually, the term "Scrubber" means washing the unwanted contents in the gas stream using liquid. Recently, waste gases have also started to be cleaned with dry systems. Scrubbers have become an essential device for controlling acidic, basic gases and gaseous emissions. There are various methods for the elimination and neutralization of toxic or corrosive compounds from the waste gas.

Wet Scrubber (Liquid Washing Scrubber)
Combustion in factories, H2S and NH3 gases formed in Biological Wastewater Treatment plants or gases from chemical reactions in chemical wastewater treatment plants harm the environment. Scrubber system can neutralize these gases. On the basis of Wet Scrubber, it depends on washing the waste gases with chemicals that will neutralize these gases in a tower or container. Waste gases are drawn from a closed system (a room or covered pools) with a fan and sent to the Scrubber system.

The gas or odor desired to be neutralized in the scrubber tower is processed using some chemicals. There are nozzles that spray water inside the tower. These nozzles wash the air passing by slowing down plastic objects called rashing rings.

Decelerated air meets liquid containing chemical scrubber thanks to rashing rings. At this point, the gases that cause the formation of odor mix into the water. The chemicals given into the scrubber are dosed at a certain rate by reading the information coming from pH meters, oRP meters or conductivity measuring devices.

Odorless gas comes out from the scrubber tower. The water in the scrubber is changed periodically and the system continues to operate.
