Introduction

Ensuring the quality of drinking water is a crucial aspect of public health, and monitoring ammonia nitrogen levels is a vital step in maintaining water quality. The Tirtanadi Sunggal PDAM Drinking Water Treatment Installation in Medan, Indonesia, has implemented a colorimetric method to determine the levels of ammonia nitrogen in reservoir water. This method involves using a DR/890 colorimeter with the addition of ammonia cyanurate powder reagents and ammonia salicylate powder reagents. In this article, we will discuss the analysis and explanation of the colorimetric method, the importance of monitoring ammonia nitrogen levels, and the conclusion of the study.

Analysis and Explanation of Colorimetric Methods

The colorimetric method is a widely used chemical analysis technique that measures the concentration of substances based on the intensity of the color of the solution. In the context of determining ammonia nitrogen levels in reservoir water, this method is particularly useful. Ammonia nitrogen is an important parameter that needs to be monitored because it can reflect the level of pollution and affect the water quality that will be consumed by the community.

In the testing process, the reservoir water is mixed with a special reagent that will react to form a colored complex. The resulting color intensity is then measured using a colorimeter. Accurate reading of the colorimeter will allow us to know the concentration of ammonia nitrogen in water samples. The colorimetric method is a reliable and efficient technique for determining ammonia nitrogen levels, and it has been widely used in various water treatment plants.

The Importance of Monitoring Ammonia Nitrogen Levels

Monitoring ammonia nitrogen levels in water is very important to maintain drinking water quality. High ammonia levels can indicate pollution from domestic or industrial waste that can endanger health. With routine testing, as did in PDAM Tirtanadi, we can ensure that the water that is supplied to the community is safe for consumption. Ammonia nitrogen levels can also affect the taste, odor, and color of water, making it unpleasant for consumers.

In addition, high ammonia levels can lead to the formation of toxic compounds, such as nitrosamines, which can cause cancer and other health problems. Therefore, it is essential to monitor ammonia nitrogen levels regularly to prevent these potential health risks. The colorimetric method is a simple and cost-effective technique for monitoring ammonia nitrogen levels, making it an ideal choice for water treatment plants.

The Role of the Tirtanadi Sunggal PDAM Drinking Water Treatment Installation

The Tirtanadi Sunggal PDAM Drinking Water Treatment Installation in Medan, Indonesia, has implemented the colorimetric method to determine the levels of ammonia nitrogen in reservoir water. The installation uses a DR/890 colorimeter with the addition of ammonia cyanurate powder reagents and ammonia salicylate powder reagents. The results of the analysis showed that the ammonia nitrogen level of 0.07 mg/l, which is in accordance with the standards set by the Ministry of Health of the Republic of Indonesia in Regulation No.492/Menkes/Per/IV/2010.

Conclusion

Through the colorimetric method, PDAM Tirtanadi in Medan Sunggal has succeeded in determining the level of ammonia nitrogen with satisfying results, which is 0.07 mg/l. These results indicate that the reservoir water quality is in accordance with the standards set by the Ministry of Health. Therefore, it is essential for all relevant agencies to continue to test and supervise water quality so that people can obtain clean and healthy water.

Recommendations

Based on the results of this study, the following recommendations are made:

The colorimetric method should be used regularly to monitor ammonia nitrogen levels in reservoir water.
The results of the analysis should be compared with the standards set by the Ministry of Health to ensure that the water quality meets the required standards.
The water treatment plant should take necessary measures to prevent pollution and maintain the quality of the water.
The public should be educated on the importance of monitoring water quality and the potential health risks associated with high ammonia levels.

Future Directions

Future studies should focus on the following areas:

Developing more efficient and cost-effective methods for monitoring ammonia nitrogen levels.
Investigating the effects of different reagents on the accuracy of the colorimetric method.
Conducting regular monitoring of ammonia nitrogen levels in reservoir water to ensure that the water quality meets the required standards.

By following these recommendations and future directions, we can ensure that the water supplied to the community is safe for consumption and meets the required standards.
