Introduction

Drinking water treatment is a crucial aspect in maintaining public health. To ensure good water quality, PDAM Tirtanadi Delitua branch routinely conducts analysis of heavy metal content such as iron (Fe) and Mangan (MN) in raw water and reservoir water. This study aims to determine the quality of raw water and reservoirs using the colorimetric method and assess its feasibility based on the Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/PER/IV/2010 concerning Terms and Supervision of Drinking Water Quality.

Background

The quality of drinking water is a significant concern for public health. Heavy metals such as iron (Fe) and manganese (MN) can be present in raw water and reservoirs, which can pose health risks if not properly treated. The colorimetric method is a widely used technique for determining the concentration of solutes in water, including iron (Fe) and manganese (MN). This method is relatively easy, fast, and cost-effective, making it an ideal choice for routine water quality analysis.

Methodology

This study uses the colorimetric method to determine the level of iron (Fe) and manganese (MN) in raw water and reservoir water. The analysis was conducted using a spectrophotometer, which measures the absorbance of light by the sample. The results were then compared to the standard limits set by the Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/PER/IV/2010.

Results

The analysis results show that the iron content (Fe) in raw water reaches 0.72 mg/l, while the manganese level (MN) reaches 0.261 mg/l. Meanwhile, the iron content (Fe) in the reservoir water recorded 0.08 mg/l and the manganese level (MN) 0.00575 mg/L. These results indicate that the quality of raw water and reservoirs in the Tirtanadi PDAM Delitua Branch of Drinking Water Treatment Installation meets the standard stipulated in the Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/Per/IV/2010.

Discussion

The results of this study show that the water treatment process carried out at the installation is successful in reducing iron levels (Fe) and manganese (MN) in raw water so that it meets the quality requirements of drinking water. This is a significant achievement, as it ensures that the drinking water provided to the community is safe and of good quality.

Drinking Water Quality Standards

The Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/Per/IV/2010 sets the maximum limit of iron (Fe) and manganese (MN) in drinking water, which is 0.3 mg/l for iron (Fe) and 0.1 mg/L for manganese (MN). These standards are designed to protect public health and ensure that drinking water is safe for consumption.

Benefits of Colorimetric Analysis

The colorimetric method allows for fast and simple analysis to measure the concentration of solutes in water, including iron (Fe) and manganese (MN). This is very useful in monitoring water quality regularly, as it enables water treatment plants to take corrective action if necessary.

Importance of Water Treatment

Appropriate water treatment is very important for removing harmful substances such as iron (Fe) and manganese (MN) from raw water. The processing includes coagulation, flocculation, sedimentation, filtration, and disinfection. These steps are crucial in ensuring that the drinking water provided to the community is safe and of good quality.

Conclusion

In conclusion, analysis of iron levels (Fe) and manganese (MN) using the colorimetric method in the Tirtanadi PDAM Delitua PDAM water treatment installation shows that the quality of raw water and reservoirs meet the established standards. This shows the commitment of PDAM Tirtanadi in providing safe and quality drinking water for the community.

Recommendations

Based on the results of this study, it is recommended that the water treatment process at the installation be continued and monitored regularly to ensure that the quality of drinking water meets the established standards. Additionally, the use of the colorimetric method for routine water quality analysis is recommended, as it is a fast and simple technique that provides accurate results.

Limitations

This study has several limitations, including the use of a single analytical method (colorimetric method) and the limited number of samples analyzed. Future studies should aim to use multiple analytical methods and analyze a larger number of samples to provide a more comprehensive understanding of the water quality in the Tirtanadi PDAM Delitua Branch of Drinking Water Treatment Installation.

Future Directions

Future studies should aim to investigate the effectiveness of the water treatment process in removing other contaminants from raw water, such as bacteria and viruses. Additionally, the use of advanced analytical techniques, such as mass spectrometry, should be explored to provide a more comprehensive understanding of the water quality in the Tirtanadi PDAM Delitua Branch of Drinking Water Treatment Installation.
