Correct answer: B. Particulate matter from gas streams
- A. Dissolved salts from wastewater
- B. Particulate matter from gas streams
- C. Nitrogen gas from combustion air
- D. Noise from industrial machinery
Explanation
A baghouse passes polluted gas through fabric bags that trap particulate matter on their surfaces. It is not primarily designed for dissolved contaminants, nitrogen separation or noise control.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
