Industrial air pollution is the major source of pollution contributing to deteriorating air quality, major health effects on humans, green house gas emissions etc.

TECHNOLOGICAL MEASURES:–

• AT SOURCE :- Adoption of clean and new technology i.e Industries can use modified chimneys to reduce air pollution, affluent treatment plants , zero discharge methods etc .
• Cleaning Smokestacks and Exhaust Pipes:-The leading sources of air pollutionare power plants, factories, and vehicles. They constantly emit fumes and gaseous waste into the atmosphere. In power plants and manufacturing industries, electrostatic smoke precipitators that use static electricity to trap soot and dust from the gaseous waste leaving the smokestacks is a significant technological cleaning measure which can be used to control air pollution.
• Mechanical devices generally work on the basis of the following:
  – Gravity: In this process, the particles settle down by gravitational force.
  – Sudden change in direction of the gas flow. This causes the particles to separate out due to greater momentum.
• Fabric Filters: The gases containing dust are passed through a porous medium. These porous media may be woven or filled fabrics. The particles present in the gas are trapped and collected in the filters. The gases freed from the particles are discharged.
• Wet Scrubbers: Wet scrubbers are used in chemical, mining and metallurgical industries to trap SO2, NH3, metal fumes, etc.
• Electrostatic Precipitators: When a gas or an air stream containing aerosols in the form of dust, fumes or mist, is passed between two electrodes, then, the aerosol particles get precipitated on the electrode.

Meteorological Controls:-

• Wind speed data to Disperse the pollutants.
• Determining height of the Chimney
• Rainfall and Convection of Air to Decrease Pollutants in Air.
• Air Quality Indicators and Warning systems.
• Meteorological Control option can be use of human induced rains that is cloud seeding technologies to reduce pollution i.e as done in Beijing.
