Venturi Wet Scrubbers
A Venturi Scrubber can be engineered to collect both particulate and gas pollutants. That being said, the most efficient use of a Venturi Scrubber is to remove particles. Packed towers, FGD, and other scrubber technology are more efficient at removing gas pollutants.

Packed Tower Wet Scrubbers Packed tower scrubbers, also called packed bed or packed column scrubbers, are best for getting rid of gas phase emissions like sulfur dioxide or other odors and acids.
Impingement Wet Scrubbers
Impingement scrubbers are your go-to devices for dealing with practically any other type of particulate matter with particles larger than 5 µm or soluble gases. They especially excel when working with dryers and powdered products, like salt and food flavorings.
No matter what industry you’re in or what type of pollutants you’re dealing with, picking the right wet scrubber for the job will be key to getting the most out of your air pollution control system.
In these types of scrubbers, gas enters from the bottom of the tower and travels upward through openings in horizontal perforated trays while a scrubbing liquid flows from the top and over each tray, mixing with the gas.
