Investigating the effect of the "sedimentation chamber" on reducing the dust pollution in house interior (Case Studies: A House in Dezful)

One of the most important natural hazards in the southwest is dust pollution. Dust pollution increase in recent years and became a serious problem in the region. This pollution situation in southwestern Iran is also noticeable. The continued presence of dust pollution can impose irreparable damage on the health of the community and the environment over the next few years. Therefore, it is necessary to use measures to deal with the problem. Due to the difficulty of reducing air pollution in the city and outdoors, paying attention to the indoor area will have a major contribution to health. In these circumstances, the main goal of the research is to find a solution that can remove dust from an indoor area (without applying harmful chemicals). In this research, while studying the conventional methods of dust purification, the "sedimentation chamber" method has been selected. In this research, an experimental sample of a sedimentation chamber in the house was built and tested, and from these experiments, daily data on the amount of dust collected in different spaces (Including Inside the sedimentation chamber, the research room, the adjacent room, the yard space, the amount of wind speed entering the chamber) were collected and measured. Analyzing the data collected, the results were inspected. Eventually, the effect of the sedimentation chamber has been proven in the purification of dust inside the house (in comparison with not using it). Also, the correlation between room air purification with western wind velocity (positive pressure) in 73% of cases there was a direct correlation. As a result, the use of the chamber is suggested as a way to deal with the Dust pollution in the interior of the house.
