The objective of research is investigation on characteristics of Particulate Matter (PM) on the food storage room using electrostatic precipitation (ESP). The filter of ESP is a technic of filtration device that removes fine particles gas using the force of an induced electrostatic charge and corona discharge produced by DC high voltage. The experimental research is conducted with the ESP Filter and smoke chamber. Artificial smoke was injected in the chamber and ESP charges the particle by corona discharge that applied to reduce diameter of particulate matter (PM). The results show that the time of smoke discharge from the room is shown in figure 1. Cooper material show slightly faster than the stainless steel and aluminum. Even the results show the cooper faster than others, stainless steel is chosen for application of ESP, because the characteristic of stainless is anti-corrosive and easy maintenance.Research results by 15 mm distance plate is more effective to absorb of particulate matter in the food storage than 9 mm distance plate in both of voltages. The effectiveness of cooper material for reduce of particulate matter diameter is showed. The measurement of PM diameter is using Scanning Electron Microscope with 5000 times enlarged. Experimental data taken by SEM Phenom-Xand Sputtering Quorum. The data shows when using cooper plate, mean diameter of PM are 4.06 μm and 3.64 μm for 9 mm and 15 mm distance plate, respectively. Also, for the stainless-steel and aluminum plate shows the 15 mm distance plate the mean diameter of PM is higher than 9 mm, this is because the effect of corona needs some space between plate for the reaction. One of the main advantages of ESP system is that various types of dust, mist, droplets, etc., can be collected under both dry and wet conditions and also submicron size particles can be collected with high efficiency.
