1 environment air plollution The goal for all control strategies is to achieve real and measurable air emission reductions. Air pollution is due to emissions of pollutants in the atmosphere, which may be natural or of human origin. Contribution of air pollution control system to wastewater and solid waste. The contamination of air can be caused due to many factors such as poisonous or harmful gases, smoke, fog, smog, dust, etc. Such devices include scrubbers, adsorption systems, condensers, flares, and incinerators. Air/fuel (A/F) ratio, which is controlled by the carburetor or fuel injection system, is the most important variable in determining emissions and in applying catalyst technology. There are two main types of scrubbers that we will discuss: wet scrubbers and dry scrubbers. Therefore, the meteorological phenomena of the lower layers of the atmosphere are the most relevant to understand and analyze air pollution. air pollution affects both plants as well as animals. 1 USING BIOREACTORS TO CONTROL AIR POLLUTION INTRODUCTION The most basic solution for air pollution is to move away from fossil fuels, replacing them with alternative energies like solar, wind and geothermal. iii.

Air pollution is usually treated in terms of the monitoring, control and management of the so-called major (criteria) pollutants - CO and CO 2 , SO 2 and SO 3 , NO x , particulates and volatile . Control of the pollutant at the source can be accomplished in several ways: Raw material changes. The air pollution definition says that when any physical, chemical, or biological change takes place in the air and contaminates it, then it is called air pollution. Acidic precipitation is highly fatal for aquatic flora and fauna, monuments, and also for natural vegetation. electrostatic precipitator, also called electrostatic air cleaner, a device that uses an electric charge to remove certain impuritieseither solid particles or liquid dropletsfrom air or other gases in smokestacks and other flues. 6. Similarly to incineration devices, biofilters destroy the pollutants to reduce the amount present in industrial emissions and exhaust. Air pollution is the introduction of particulates, biological molecules, or other harmful substances into Earth's atmosphere, causing diseases, allergies, death to humans, damage to other living organisms such as animals and food crops, or the natural or built environment. Step 4: Gas Sensor Circuit Board. Constituted in September, 1974. Pollutants can be in the form of solid particles, liquid droplets, or gases. When we will connect it to Arduino then it will sense the gases, and we will get the Pollution level in PPM (parts per million). WTE facility's air pollution control devices, including scrubbers, (which neutralize acid gases and control mercury), baghouses, (which remove . Furthermore, most air pollution sources are located near the Earth's surface (some exceptions include tall stacks, aircraft emissions, and volcanic eruptions). Chelsea, Mich.: Lewis Publishers. The MQ135 sensor can sense NH3, NOx, alcohol, Benzene, smoke, CO2 and some other gases, so it is perfect gas sensor for our Air Quality Monitoring Project.
