Over past few years, team is working closely with Biomass & Fossil fuel fired Power plants in Thailand to help reduce the Dust Emission
Dust pollution refers to the release of pollutants into the air that are detrimental to human health and the planet as a whole.
The Clean Air Act authorizes the U.S. Environmental Protection Agency (EPA) to protect public health by regulating the emissions of these harmful air pollutants.
“Most air pollution comes from energy use and production,” says Environment experts.
Burning fossil fuels releases gases and chemicals into the air
Human health effects of dust relate mainly to the size of dust particles. Dust may contain microscopic solids or liquid droplets that are small enough to get deep into the lungs and cause serious health problems. Large particles may irritate the nose, throat and eyes. The particle size is a major determinant of how serious the health effect will be, especially for lung diseases and the effects on the heart.
Small particles less than 2.5 micrometres in aerodynamic diameter (called PM2.5) pose the greatest problem because they can get deep into the lungs and some may get into the bloodstream. The particles can come from industry such as foundries, and diesel engines. Those that are smaller than 10 micrometres in aerodynamic diameter (called PM10) can also cause serious health effects in susceptible individuals if the concentration is high enough.
These two are the most prevalent types of air pollution. Smog, or “ground-level ozone,” occurs when emissions from combusting fossil fuels react with sunlight. Soot, or “particulate matter,” is made up of tiny particles of chemicals, soil, smoke, dust, or allergens, in the form of gas or solids, that are carried in the air.
The sources of smog and soot are similar. “Both come from cars and trucks, factories, power plants, incinerators, engines—anything that combusts fossil fuels such as coal, gas, or natural gas,” The tiniest airborne particles in soot—whether they’re in the form of gas or solids—are especially dangerous

We promote dust filtration technology called as ‘Electrostatic Precipitator’
An electrostatic precipitator (ESP) is a filtration device that removes fine particles, like dust and smoke, from a flowing gas using the force of an induced electrostatic charge.
In contrast to wet scrubbers, which apply energy directly to the flowing fluid medium, an ESP applies energy only to the particulate matter being collected and therefore is very efficient in its consumption of energy.
Invented back in 1824 in Europe by a German scientist but it was commercialized in 1907 after research & development done by University of California.
The most basic precipitation contains a row of thin vertical wires, and followed by a stack of large flat metal plates oriented vertically, with the plates typically spaced about 1 cm to 18 cm apart, depending on the application.
The air stream flows horizontally through the spaces between the wires, and then passes through the stack of plates.
A negative voltage of several thousand volts is applied between wire and plate. If the applied voltage is high enough, an electric corona discharge ionizes the air around the electrodes, which then ionizes the particles in the air stream.
The ionized particles, due to the electrostatic force, are diverted towards the grounded plates. Particles build up on the collection plates and are removed from the air stream.
