Study Notes
Air Pollution Control Techniques
- Air pollution control techniques involve reducing the impact of air pollution through various methods and devices
- The techniques can be categorized into engineering controls, operating and management procedures, and inspection and performance monitoring
Engineering Controls
- Engineering controls involve using devices to reduce air pollution
- Types of air pollution control devices include:
- Fabric filtration
- Electrostatic precipitators
- Cyclonic separators for particulates
- Particulate scrubbers
- Ceramic filters
- Particulate pre-treatment systems
- Biofiltration
- Thermal oxidation of gaseous contaminants
- Scrubbing and adsorption systems
- Adsorption systems
- Fugitive dust control
Fabric Filtration
- Fabric filtration uses a fabric to filter out pollutants from the air
- The fabric is designed to capture particles of a certain size
- The fabric can be replaced or cleaned when it becomes clogged
Electrostatic Precipitators
- Electrostatic precipitators use an electric charge to attract pollutants
- The pollutants are then collected on a surface or in a container
- Electrostatic precipitators are often used for large-scale industrial applications
Cyclonic Separators
- Cyclonic separators use a spinning motion to separate particles from the air
- The particles are collected in a container or bag
- Cyclonic separators are often used for dust collection
Particulate Scrubbers
- Particulate scrubbers use a liquid to capture pollutants
- The pollutants are then removed from the liquid through sedimentation or filtration
- Particulate scrubbers are often used for wet scrubbing applications
Ceramic Filters
- Ceramic filters use a ceramic material to filter out pollutants
- The ceramic material is designed to capture particles of a certain size
- Ceramic filters are often used for high-temperature applications
Biofiltration
- Biofiltration uses microorganisms to break down pollutants
- The microorganisms are introduced into the air stream or onto a surface
- Biofiltration is often used for odor control and VOC removal
Thermal Oxidation
- Thermal oxidation uses heat to break down pollutants
- The pollutants are converted into carbon dioxide and water
- Thermal oxidation is often used for VOC removal and odor control
Management of Fuel Burning
- Management of fuel burning involves controlling NOx emissions
- Boiler combustion efficiency testing and tuning can help reduce NOx emissions
- Fuel switching can also help reduce NOx emissions
Operation and Management Plans
- Operation and management plans involve regular maintenance and inspection of air pollution control devices
- The plans should include procedures for startup and shutdown, as well as emergency response
- The plans should also include training for operators and maintenance personnel
