Air Pollution Control Systems

Air pollution control systems are required in many industrial facilities due to health and safety regulations enforced by the Environmental Protection Agency (EPA) as well as State and local agencies. Pollution control exhaust systems comply with the Clean Air Act (CAA), a federal law that was created in 1970 to prohibit stationary and mobile air emissions from exuding into the atmosphere. Air pollution control system types vary from industry to industry, depending on the type of hazardous agents needing to be eliminated. Because of the corrosive nature in many of these emissions, corrosion resistant ventilation systems are the standard. Each system is comprised of numerous components, including mist eliminators, ducts, hoods, exhaust fans, and fume scrubbers.

Ductwork, or a duct system, consists of tubes or hoses that supply, return, and exhaust air. Properly installed ductwork ensures satisfactory indoor air quality, and filters any air pollution. Nearly all industries utilize some type of duct system for clean air. Ducts are produced from a variety of materials. Corrosive air streams from industrial processes require duct to be designed from materials such as PVC or Polypropylene.

Fume and exhaust hoods are durable ventilation systems designed to maintain a high quality of air by capturing emitted toxins. Fume hoods help limit personnel exposure to chemical fumes, gases, vapor, and more. Hoods for industrial chemical processes are generally manufactured out of corrosion resistant materials such as PVC or Polypropylene.

Another component of industrial ventilation systems is the Exhaust Fan or Exhaust Blower, which can be installed either inside a facility or on top of the roof. Unwanted odors, particulates, smoke, and vapor are ventilated vertically or horizontally out through a centrifugal belt driven, direct driven, or inline fan. Exhaust fans used for industrial processes such as electroplating or galvanizing are also manufactured from thermoplastic materials.

Wet Scrubbers are large (vertical or horizontal) air pollution control units, which are used for the removal of numerous hazardous air pollutants (HAPs). Common types of scrubbers used for industrial chemical process are wet packed tower scrubbers. They remove odorous gases and acids using continuous recirculation of the scrubbing solution. Many municipal waste treatment plants use wet scrubbers for odor control purposes by removing Hydrogen Sulfide from the air stream.

Air pollution control systems are essential for healthy indoor and outdoor environments. They make it possible for industries to meet national polution control standards for clean air. They are also an excellent way to improve indoor air quality, saving businesses time and money by improving production rates and lowering health-related absences.
