Air pollution control systems for food industries

Air pollution control systems are widely used in working with plants, engineers, and operators in the food and beverage industry. The thing is that food industries produce numerous liquid wastes that generally include high levels of FOG (fats, oils, and grease), starch, BOD, and solids, which need for modified air treatment processes. Herewith, proper targeting of each air pollutant for economic and efficient treatment plays a crucial role.

It should be noted that air pollution is regarded as a serious problem for in-plant operations and exhaust emissions. The thing is that air pollutants such as oils, particulate, moisture, and acid/alkaline gasses can be found in a food manufacturing process. Herewith, air pollution control needs careful attention for correct capture, filtration, neutralization, and disposal.

Numerous manufacturers of air pollution control systems provide air treatment equipment, for instance, for dryers, ovens, cooking kettles, spray coating lines, and numerous other processes that create irritating and harmful constituents. Additionally, air pollution control has several requirements that all air treatment devices should meet (use of food-grade motors, instrumentation, and materials of construction).

Also, manufacturers of air pollution control systems have the experience required to provide air treatment solutions for challenging applications where traditional treatment devices have unsucceeded. Devices provided air pollution control are perfect in the following food manufacturing processes: breweries, soft drink production, wineries, cheese production, bottling, food packaging, etc.

Thus, air pollution control systems are considered to be successfully engineered, fabricated, and installed in food and beverage production plants. They allow treating acid, alkaline gasses, and fumes, particulate matters, providing odor control, dust collection, and dryer exhaust. Air treatment devices such as scrubber systems can remove particulates from a dryer before VOC destruction with a regenerative thermal oxidizer.

Scrubber systems are the following:

  • Venturi scrubber with tunable scrubbing throat;
  • A cyclonic separator that has chevron-type, high-efficiency mist eliminator;
  • Reservoir for liquid with level control and make-up water valve;

Herewith, scrubber systems, the separator, and reservoir for liquid are designed from 304 stainless steel.

  • Recirculation pumps – operating, stand-by;
  • Flowmeter, pressure transmitters, and associated liquid valves/piping;
  • Instruments wired to the local junction box for integration with the RTO control panel.

If you search for the best air treatment device to improve air quality, you can buy a high-tech completely new type of wet scrubber – a Multi-Vortex wet air scrubber produced by Redwood Technology.

Redwood technology is a fast-growing vendor of wet air scrubbers. The multi-vortex scrubber can remove gas emissions, dust, vapors, and other pollutants from a gas stream. It is an innovative technology created to save water that makes it more cost-efficient and differs from other types of scrubbers.  If you have any questions or would like to purchase a multi-vortex wet air scrubber, please contact us at
