“…Back-corona discharge and dust reentrainment can be totally avoided because dusts collected on the plates are removed continuously by water film (Mizuno, 2000). Numerous studies have been done on the performance of wet ESP, including the investigations of geometric parameters, electrode material, and material surface treatments (Kim et al, 2010;Chang et al, 2011;Jeong et al, 2013;Najafabadi et al, 2014). Some researchers investigated the effects of water on particle removal in laboratory-scale wet ESP.…”

This work tends to study the particle migration and collection under spraying condition. The performance of a wet electrostatic precipitator (ESP) is evaluated in terms of the corona discharge characteristics, total particle removal efficiency, and fractional particle removal efficiency. The effects of water droplets on particle removal, especially on removal of particles with different sizes, is investigated. The optimization work was done to determine appropriate water consumption, discharge electrode type, and specific collection area, which can provide a basis for wet ESP design and application.

“…Intriguingly, the TVOC removal ratios in the field test decreased sooner than in the laboratory test. In this case, TSPs were removed by the HEPA filter and electrostatic precipitation in the plasma treatment [12,13]. However, as mentioned in Section 2.4, TVOC removal was easily affected by catalyst poisoning and adsorption/desorption of VOCs on the filters during long-term field use.…”

A practical and long-term usable air-cleaner based on the synergy of photocatalysis and plasma treatments has been developed. A field test of the air-cleaner was carried out in an office smoking room. The results were compared to previously reported laboratory test results. Even after a treatment of 12,000 cigarettes-worth of tobacco smoke, the air-cleaner maintained high-level air-purification activity (98.9% ± 0.1% and 88% ± 1% removal of the total suspended particulate (TSP) and total volatile organic compound (TVOC) concentrations, respectively) at single-pass conditions. Although the removal ratio of TSP concentrations was 98.6% ± 0.2%, the ratio of TVOC concentrations was 43.8% after a treatment of 21,900

“…For particles lower than 1 μm, diffusion charging is the dominant charging mechanism. The number of charges for field charging, n f t ð Þ, and that for diffusion charging, n d t ð Þ; can be estimated from the following equations (Lin, Chen, & Tsai, 2012;Chen, Tsai, Yan, & Li, 2014;Najafabadi, Tabrizi, Aramesh, & Ehteram, 2014).…”
