title = "Removal characteristics of yellow sand dusts using plasma air cleaning systems for improving indoor air quality",
abstract = "Yellow sand dust (Asian dust storm) causes harmful damage indoor and outdoor during the springtime, and the removal of yellow sand dust an issue for suitable indoor conditions. An air cleaner is required to remove yellow sand dust efficiently to improve indoor air quality, and the removal characteristics of yellow sand dust should be conducted. The size distribution and mass concentration of yellow sand dust observed in China and Korea are analyzed, and the removal efficiency of a plasma air cleaning system based on the principle of electrostatic precipitation is evaluated using yellow sand dust. Mass median diameter of yellow sand dust sampled in Beijing and Seoul ranges from 7.0 to 8.0 μm with the mass concentration of 300-1,462 μg/m3. For the single-pass test, the efficiency of dust removal increases with increasing particle size and decreasing flow rate. The removal efficiency of yellow sand dust in the plasma air cleaning system at the face velocity of 1.0 m/s is larger than 80%. For the multi-pass test in occupied spaces, the operation time required to reduce yellow sand dust concentration from the initial concentration of 300 μg/m3 to 150 μg/m3, the criteria of indoor air quality, is 10 minutes for the test room of 27 m3. The plasma air cleaning system is suitable for the removal of yellow sand dust for maintaining suitable indoor air quality.",
