What efficiency can fabric filters achieve in a plant?

Fabric filters are highly effective air pollution control devices that can achieve very high levels of efficiency in removing particulate matter from exhaust streams. These filters work by passing dirty air through a fabric material, which captures particles due to various mechanisms such as interception, inertial impaction, and diffusion.

In many industrial applications, fabric filters can surpass 99% efficiency, making them one of the top choices for controlling emissions, especially in plants that require stringent air quality standards. The ability to filter out such a high percentage of particulate matter helps improve the overall air quality and reduces environmental impact, which is critical in facilities that deal with processes generating significant dust or other particulates.

While other options depict lower efficiency levels, they do not reflect the capability of fabric filters under optimal operating conditions. This high efficiency is crucial for plants to comply with regulatory requirements and to meet sustainability goals.
