Introduction to Industrial Scrubbers

If you are a plant manager, a process engineer, or a purchasing or Environmental Health and Safety (EHS) professional who works in industrial manufacturing or the wastewater treatment industry, then you may be seeking a solution to remove harmful pollutants and odors from your process exhaust streams before they are released into the atmosphere and contaminate the outside air. One technology worth strong consideration is the industrial scrubber.

Industrial scrubbers are pollution filtration systems that utilize solids (in “dry scrubbers”), or water or other liquids (in “wet scrubbers”) to remove gas pollutants and odors from exhaust streams. In general, the main advantages of industrial scrubbers to clean gas exhaust streams include:

• Low-risk processing of incendiary gases
• Ability to handle high-temperature, high-humidity gas streams without temperature limit or condensation problems
• Small space requirements mean lower capital costs and site location flexibility – scrubbers reduce the temperature and volume of unsaturated exhaust streams, permitting vessel sizes, fans and ducts to be more compact. This also enables retro-fitting into existing systems
• No secondary dust sources – once particulate matter is collected, it cannot escape from hoppers or during transport
• Ability to absorb gas and solid particulate matter via a single device
• Ability to neutralize corrosive gases
