Abstract

Background: Water is a component of life that cannot be separated from human life. There are several parameters that must be considered, one of which is chemical parameters in the form of iron (Fe) and manganese (Mn). Excessive levels of iron (Fe) and manganese (Mn) in water will cause health and environmental problems, so water treatment is needed to overcome these problems. Research objective: to find out the difference in levels of iron (Fe) and manganese (Mn) in dug well water before and after treatment with the cascade aerator method. Research Methods: This research is a quasi-experimental research with Pre Test Post Test Group Design. The research was conducted in November 2021-January 2022. The object of this research is the dug well water belonging to Mrs. Y which is located in Sawit Hamlet, Panggungharjo, Sewon, Bantul. The research was conducted using the cascade aerator method with dimensions of height for each step of 25 cm, diameter of steps of 30 cm and width of 28 cm. samples obtained were 5 pre samples and 5 post samples. Result: There is a difference between the levels of iron (Fe) before and after treatment with a cascade aerator, the average decrease in levels of iron (Fe) after filtering is 24.97%. The results of the bound T-Test obtained a sig value of 0.005. There is a difference between the levels of manganese (Mn) before and after treatment with a cascade aerator, the average decrease in manganese (Mn) levels after filtering is 26.07%. The results of the bound T-Test obtained a sig value of 0.010. From these data, it can be concluded that the cascade aerator can reduce the levels of iron (Fe) and manganese (Mn) in dug well water. Keywords: water treatment, cascade aerator, iron (Fe), manganese (Mn)
