Wet Or Water Scrubbers

Wet scrubbers are air pollution control devices that use a liquid (usually water) to remove pollutants from an air stream. These devices are commonly employed in industrial processes to control particulate matter, gases, and other pollutants emitted during manufacturing and processing operations.
Wet or water scrubbers operate on the principle of contacting the polluted air with the liquid, which then captures and removes the contaminants. Water scrubbers, also known as wet scrubbers or wet gas scrubbers, are essential equipment in chemical plants for controlling air pollution and removing harmful gases from industrial exhaust streams.
Manufacturing wet or water scrubbers involves a series of processes that encompass design, fabrication, assembly, testing, installation and commissioning on site.
In conclusion, Wet or water scrubbers play a vital role in chemical plants by controlling emissions and ensuring compliance with environmental regulations. Their versatility and effectiveness make them indispensable for maintaining air quality and sustainability in industrial settings
Key Components of Wet or Water Scrubbers

Scrubbing Chamber:
The scrubbing chamber is where the interaction between the polluted air and the liquid (scrubbing medium) takes place. It is designed to maximize the contact between the air and the liquid to facilitate the capture of pollutants.
Scrubbing Medium:
The liquid used in the scrubbing process serves as the scrubbing medium. It can be water or a water-based solution, and additives may be used to enhance pollutant removal efficiency.
Spray Nozzles or Gas Distributors:
Spray nozzles or gas distributors are used to disperse the scrubbing medium into the scrubbing chamber in the form of droplets. This helps create a large surface area for contact with the polluted air.
Inlet and Outlet Ducts:
Inlet ducts bring the polluted air into the scrubber, and outlet ducts carry the cleaned air out of the system.
Fan or Blower:
A fan or blower is often used to create the necessary airflow through the scrubber. This helps maintain the desired velocity for effective pollutant capture.
Liquid Re-Circulation System:
In some wet scrubber designs, a liquid re-circulation system is employed to reuse and conserve the scrubbing medium. This system may include pumps, tanks, and control mechanisms.
Demister or Mist Eliminator:
A demister or mist eliminator may be installed at the outlet to remove any remaining liquid droplets from the cleaned air before it is discharged.
Control System:
The control system includes instruments and devices to monitor and control parameters such as liquid flow rate, pressure, and pH levels to optimize scrubber performance.
Types of Wet or Water Scrubbers

Venturi Scrubbers:
Use a constriction in the airflow (venturi throat) to create turbulence and enhance contact between the air and scrubbing liquid.
Impingement Plate Scrubbers:
Direct the polluted air through a series of plates where the liquid droplets impinge on and capture the pollutants.
Packed Bed Scrubbers:
Use a packed bed of materials (such as plastic or metal packing) to create a large surface area for contact between the air and liquid.
Spray Tower Scrubbers:
Direct the polluted air through a tower where liquid is sprayed from the top, creating a counterflow of air and liquid.
Wet Electrostatic Precipitators (Wet ESPs):
Use electrostatic forces to charge particles, which are then collected in a liquid film.
Scrubbing Systems for Gases:
Designed specifically for removing acidic gases, such as sulfur dioxide (SO2) and hydrogen chloride (HCl), from industrial emissions.
Working Principle of Wet or Water Scrubbers

Contact and Absorption:
Polluted air is introduced into the scrubbing chamber, where it meets the liquid spray. Pollutants are absorbed into the liquid.
Chemical Reaction (if applicable):
In some cases, a chemical reaction between the pollutants and the scrubbing medium may occur, resulting in the formation of water-soluble compounds.
Cleaning and Collection:
The scrubbed air is cleaned of contaminants, and the liquid captures particulate matter and gases.
Separation and Disposal:
The collected pollutants are separated from the liquid through demisting or other separation methods. The cleaned air is discharged, and the separated pollutants may be treated or disposed of according to regulations.
Applications of Wet or Water Scrubbers

Industrial Emissions Control:
Wet scrubbers are widely used in industries such as metal processing, power generation, cement production, and chemical manufacturing to control emissions.
Particulate Matter Removal:
Effective for removing particulate matter, including dust, from industrial processes.
Gas Scrubbing:
Used for scrubbing gases containing pollutants like sulfur dioxide (SO2), hydrogen chloride (HCl), and ammonia (NH3).
Odor Control:
Applied in facilities where odorous compounds need to be removed from the air.
Chemical Processing:
Applied in chemical manufacturing for removing and neutralizing acidic gases.
Cooling and Condensing:
Used for cooling and condensing hot gases, often in conjunction with pollutant removal.
Benefits of Wet or Water Scrubbers

Versatility:
Wet scrubbers are versatile and can be customized for different applications and pollutants.
High Removal Efficiency:
Provides high removal efficiency for both particulate matter and gases.
Suitable for Variable Loads:
Can handle varying gas flows and pollutant concentrations, making them suitable for fluctuating process conditions.
Effective for High Temperatures:
Can operate at high temperatures, making them suitable for applications with hot gas streams.
Odor Control:
Effective in controlling and removing odors associated with industrial processes.
While wet or water scrubbers are effective in many applications, their design and selection should consider factors such as the type of pollutants, gas temperature, and the desired level of pollutant removal. Regular maintenance is also essential to ensure optimal performance.
Site Installations of Wet or Water Scrubbers
ARIA Offers complete turnkey solutions for clients not having inhouse maintenance teams to undertake site installations.
Our Site technicians and engineers travel from South Africa or India depending on the location of installations.
All our technicians and engineers are highly skilled and experienced in undertaking Wet Scrubbers installation in as little as 4 days depending on the size of the Wet or water Scrubbers
In case the client budget does not allow for site installation crew we offer a unique method of client providing local technicians and general helpers and ARIA will only send 1 engineer to guide the team to install and commission the Wet Scrubbers
