Wet scrubbers are vital components in industrial air pollution control systems. They are designed to remove particulate matter and gaseous pollutants from industrial exhaust streams. These systems are used in industries to control air pollution by removing harmful pollutants from industrial exhaust gases. These systems use liquid, often water, to capture particulate matter, gases, or vapors from an industrial stream before it is released into the atmosphere. At AKJ Industries, we design and manufacture high-quality wet scrubbers that ensure your industrial processes meet environmental standards while enhancing operational efficiency. In this blog, we will explore the working principle of wet scrubbers and why they are an essential component in your pollution control system.

What is a Wet Scrubber?
Wet scrubbers are an effective technology for the control of harmful airborne pollutants and odors in process exhaust streams. This is an air pollution control device that uses a liquid—usually water—to remove pollutants from an industrial exhaust stream. The primary function of a wet scrubber is to capture and neutralize hazardous substances before they are released into the atmosphere.
Working Principle of a Wet Scrubber
The working principle of a wet scrubber involves two main processes: absorption and collection. This scrubber uses a liquid, typically water, to capture and neutralize pollutants. Let’s break down the steps involved in the operation:
Gas Inlet: The dirty gas stream, containing pollutants, enters the scrubber. This gas can come from industrial processes such as combustion, chemical reactions, or dust generation activities. The scrubber receives the contaminated gas stream from the bottom or side.
Gas-Liquid Contact: Once inside the scrubber, the gas stream is introduced into the scrubbing chamber, where it comes in contact with the scrubbing liquid. The liquid, often water, may be augmented with chemicals to increase its efficiency in removing specific pollutants.
Pollutant Capture: As the gas stream interacts with the scrubbing liquid, particles or gases get absorbed, adsorbed, or physically trapped in the liquid phase. For instance:
- Particulate Matter: Small particles or dust are captured by the liquid droplets through impaction, interception, and diffusion.
- Gaseous Pollutants: Harmful gases like sulfur dioxide are absorbed by the scrubbing liquid and undergo chemical reactions to neutralize or transform into harmless compounds.
Cleaning and Discharge: Once the pollutants are removed from the gas stream, the cleaned gas is then released to the atmosphere. Meanwhile, the polluted liquid is either recirculated for reuse or sent for treatment, depending on the system design.
Exhaust and Monitoring: Finally, the cleaned gas exits the scrubber, and a monitoring system ensures that the emission levels meet the regulatory requirements.
Types of Wet Scrubbers
Wet scrubbers come in various designs, each suitable for specific types of pollutants and industrial applications. Some common types include:
- Packed Bed Scrubbers: A chamber filled with packing material to increase surface area for better gas-liquid contact.
- Venturi Scrubbers: Use high-pressure liquid jets to accelerate the gas and create intense mixing for efficient particle removal.
- Centrifugal Scrubbers: Utilize centrifugal force to separate pollutants from the gas stream by spinning the gas in a circular motion.
Advantages of Wet Scrubbers
- Versatility: Effective for removing both particulate and gaseous pollutants.
- High Efficiency: Can achieve high removal efficiencies for a wide range of pollutants.
- Cooling Effect: Reduces the temperature of the gas stream, which can be beneficial in certain applications.
- Neutralization: Capable of neutralizing acidic or alkaline gases through chemical reactions with the scrubbing liquid.
