Electrostatic control of domestic dust and allergen particles for improved air quality

Using Multiple-Phase Nozzles to Produce Water Droplets for Removing Smaller Dust Particles of Below MRT-BTS Saphan Khwai Station in Bangkok Thailand

“…Understandable issues are relied on the three main factors, that is, air temperature, actual vapor pressure, and wind both speed and direction in which are supposed to be effectively point sources for air pollution, gases and dust emission. (Botkin & Keller 2005;Carotenuto et al 2010;Gaunt et al 2003aGaunt et al , 2003bGrunding et al 2006;Hensley et al 2008;Gehlin et al 2003). Note.…”

“…In paralleling of aforementioned statements, Sellers (1969); Linsley et al (1988); Grim (1962); Grunding et al (2006); Hidy and Brock (1971); Baver et al (1972); Gaunt et al (2003aGaunt et al ( , 2003b; Carotenuto et al (2010); Botkin & Keller (2005); Balachandran et al (2003) have done their research works and found that wind is identified as the supporting factors for fly dust moving, particularly turbulent wind and also dry season. Also, there are suspended dust particles in the atmosphere which is high concentration in the tropopause atmospheric layer, less in the stratosphere, and very less in the mesosphere.…”

“…Normally, the fly dust (suspended dust) is surely one of the atmospheric component in the state of Brownian motion without direction according to the thermal forces of convectional process as one of heat transfer processes from vertically warmer earth surface to cooler adiabatically atmosphere, and also horizontally warmer to cooler points (Brabec, 2003;Carotenuto et al 2010;Charinpanitkul & Tanthapanichkoon 2011;Hidy & Brock 1971;Gaunt et al 2003aGaunt et al , 2003bJaworek et al 2013).

“…Theoretically, Linsley et al (1988); Botkin and Keller (2005); Gardner (1955); Gaunt et al (2003aGaunt et al ( , 2003b; Grim (1962); described that the suspended dust itself could have functioned as the negative charge particle, and readily to be absorbed by any positive-charged particles to form a bigger size with increasing weight and falling down if its weight is greater than gravitational forces. In addition, there are more 70 % of total fly dust in the atmosphere to be negative charge and hydrologically called as condensation nuclei that induces the occurrence of precipitation whenever the atmospheric moisture and cooling process are available.…”

“…In case of more concentration of hazardous gases contaminating in the sky, the precipitated toxic solution might be affected to trees, cultivated crops, animals, buildings, stream water, and archeological objects one way or another.
