The Combination of Aeration and Filtration System in Reducing Water Pollution: An Experimental Study

Abstract

This study aims to determine and analyze the combination of aeration systems with Multiple Tray Aerator and Filtration with Rapid Sand Filter in reducing iron (Fe) content in water. The source of water used is shallow well water that is still used by the community. The research design used in this study was One-Group Pretest-Posttest Design. The study located in Pangkep Regency, South Sulawesi Province, and then for the second location in Manado City, North Sulawesi Province. The number of samples with the type of experimental research was 10 with the Purposive Random Sampling technique. The instruments used in this research are Multiple Tray Aerator and Rapid Sand Filter. The results showed that the percentage of reduction using a combination of aeration and filtration systems when averaged for the two study sites, a rate of 58.50 percent obtained. The increase in iron (Fe) content, one of which is influenced by the climate at the research location, will directly increase the water temperature sources in this study, namely surface wells, which will dissolve more iron (Fe) levels. Another factor that affects iron (Fe) levels is the difference in research locations, namely on islands and coasts. This can be seen in the differences in the results of iron (Fe) levels obtained at the two research locations. Those who wish to conduct further study should pay attention to the tool's type and ability and design a more accurate model to minimize energy and cost and a more concrete form.
