Cascade Aerator Application for Removal of Fe and Mn in Dug Well Water: The Effect of Variations in Discharge, Height and Number of Cascade Contacts

Introduction

In Indonesia, the need for clean water is still a significant challenge, with around 70% of the total needs not being met. One of the main sources of clean water used by the community is groundwater obtained through wells. However, the use of groundwater is not without risk, as it often contains harmful chemicals, such as iron (Fe) and Manganese (Mn). Both have a potential negative impact on health if it is constantly used as a source of clean water and drinking water. Therefore, this research focuses on the application of the aeration method using Cascade Aerator to reduce the levels of Fe and Mn in well water.

The Importance of Removal of Iron and Manganese

The iron and manganese contained in well water can cause various problems, both for health and water quality itself. High iron levels can cause brownish color in water and provide an unpleasant taste. In addition, manganese can cause black spots on equipment and increase the risk of damage to the piping system. Therefore, the reduction in levels of these two elements is very important to improve water quality. Iron and manganese contamination can have severe consequences on human health, including gastrointestinal problems, neurological damage, and even cancer. Therefore, it is crucial to develop effective methods for removing these contaminants from well water.

Cascade Aerator Method

Cascade aerator is a device designed to improve the aeration process in water treatment. By utilizing variations of flow discharge and contact planes, this tool serves to accelerate the process of removing dissolved gas and contaminants, including Fe and Mn. In this study, testing was carried out to determine the effect of variations in flow, height, and number of contact planes from Cascade Aerator on the efficiency of removing the two chemicals. The Cascade Aerator method has been widely used in various water treatment applications, including industrial and municipal water treatment plants. However, its effectiveness in removing Fe and Mn from well water has not been extensively studied.

Effect of Variation of Debit

Varied flow discharge significantly influences the capade of cascade aerators in removing Fe and Mn. Increased flow discharge can increase the aeration rate, but can also reduce contact time between water and air, which is needed for the oxidation process. By adjusting the flow of flow, the aeration process is expected to be optimized to achieve maximum results. The optimal flow rate for the Cascade Aerator method is crucial in determining its effectiveness in removing Fe and Mn. A flow rate that is too high may lead to reduced contact time, while a flow rate that is too low may result in reduced aeration rate.

Effect of Height and Number of Contact Fields

In addition to debit, height and number of contact planes in Cascade Aerator also play an important role. The more contact areas available, the more likely the particles of Fe and Mn can be oxidized and separate from water. In addition, an increase in the high water column can also increase contact time, thereby improving the effectiveness of the aeration process. The height and number of contact planes in the Cascade Aerator method can significantly impact the removal efficiency of Fe and Mn. A higher number of contact planes and a greater height can lead to increased contact time and improved aeration rate.

Conclusion

The results of this study are expected to provide a better understanding of how to reduce the levels of Fe and Mn in well water using Cascade Aerators. Taking into account the variation of flow discharge, height, and number of contact planes, this method can be optimized to produce clean water that is safe for consumption. Through the application of this technology, it is hoped that the quality of ground water in Indonesia can improve, so that it will meet the needs of clean water for the community better. The findings of this study can contribute to the development of more effective water treatment methods in Indonesia, which can ultimately improve the health and well-being of the community.
