“…The result is consistent with the preceding obtained results given in Figure 6. This is also in line with the previous literature reported by Porteiro et al, [8] and Dramane et al, [21] that an increase in voltage leads to an increase in ESP particle collection efficiency. As a result, the quality of humid air that will be condensed is better, generating clearer and more potable water.…”

Humid air as a source of water can be utilized by using a condensation system called the Atmospheric Water Maker (AWM) in order to overcome the problem of limited drinking water supply. However, to maintain water quality and production capacity, the AWM requires an air filtration system with minimum flow resistance. In this work, an electrostatic precipitator (ESP) was used as an air filter for AWM application. Thus, this study aimed to investigate the performance of ESP in terms of particle collection efficiency and water quality produced by AWM. In order to evaluate the performance of ESP, wire to cylinder type ESP was designed and three experimental activities were performed i.e., smoke filtration test, dust filtration experiment, and AWM water quality assessment. The performance of ESP was studied at various voltages ranging from 5.8 kV to 9.7 kV and two wire mesh sizes. The results showed soot particles were successfully removed by the ESP for all applied voltages with both 1 mm and 4 mm wire mesh. The effect of ESP voltage could be observed in dust filtration experiments in which the particle collection efficiency increases with the increase of voltage. The highest particle collection efficiency was observed at a voltage of 9.7 kV with a wire mesh of 1 mm. The results also showed that the use of ESP for AWM application offered a positive effect on the quality of condensed water in which the water physical and chemical properties satisfy the WHO standard for drinking water.

This paper aims to analyse the influence of the atmospheric relative humidity level (RH) on the collection efficiency of a wire-to-plane electrostatic precipitator (WP-ESP). The experiments were performed with incense smoke particles having a mean size of about 0.28 µm. An aerosol spectrometer was employed for characterizing the size distribution of these particles at the outlet of the ESP. Then, the total and fractional collection efficiencies were estimated for different relative humidity levels ranging from 40 to 70 %. Various DC applied voltages in the case of positive and negative polarities have been under consideration. For given atmospheric conditions, the results obtained with the aerosol spectrometer show that the performances of the ESP increases with the applied voltage (range: 10 to 40 kV) and the particle diameter (range: 0.2 to 0.7 µm). The collection efficiency is higher at increased RH. The negative corona discharge is overall more effective than the positive one. However, the difference between the two polarities becomes minor at high RH.

Indoor air control of particulate matter (PM) consisted of house dust, bacteria and so on was carried out to improve indoor air quality (IAQ) using atmospheric pressure plasma [1]. Two types of corona electrodes were placed inside a reactor and energized in order to generate non thermal plasma: disc type electrode and needle type electrode. Plasma can also decompose harmful substances by various active species such as reactive radicals (N*, O*, OH*, etc), ions and strong electric field [2][3][4]. Particles collection rate depended on the discharge voltage, number of mesh filters, flow rate and reactor characteristics. The disc type electrode could collect dust, and its rate reached to 95%. The needle electrode could collect dust, and its rate was reached to 98%.Also formaldehyde removal was carried out to confirm the improving performance of non thermal plasma and reduced below the regulated value of 0.08 ppm.Index Terms-atmospheric plasma, ionic wind, corona discharge, indoor air quality, particulate matter (PM) E
