In steel and metal processing, common filtration systems include baghouse filters, electrostatic precipitators (ESPs), wet scrubbers, and cyclone separators. Baghouse filters use fabric bags to capture dust particles, while ESPs use electrical charges to remove particulates from exhaust gases. Wet scrubbers remove pollutants by introducing a scrubbing liquid, and cyclone separators use centrifugal force to separate dust from gas streams. The choice of system depends on factors such as particle size, gas temperature, and specific process requirements.

Filtration systems enhance air quality by effectively capturing and removing particulate matter and pollutants generated during metal processing. By reducing emissions, these systems help facilities comply with environmental regulations and standards, thereby minimizing their environmental impact and promoting a safer workplace.

ESPs offer high efficiency in removing fine particles, achieving up to 99% efficiency, which is particularly beneficial in steel manufacturing where flue gas emissions often contain fine dust particles. They are capable of handling large gas volumes and operate effectively at high temperatures. Additionally, ESPs have relatively low pressure drops, resulting in lower energy consumption during operation.
