The Determination of CaO Levels in Lime in Water Treatment in PDAM Tirtanadi Delitua

Introduction

Water treatment is a crucial process in providing clean and safe drinking water for the community. In Tirtanadi Delitua PDAM, the use of lime as a raw material in the water treatment process plays a significant role in improving water quality, reducing acidity levels, and precipitating unwanted particles. However, the effectiveness of this process depends on the level of calcium oxide (CaO) in the lime used. This study aims to evaluate the CaO levels in lime used by PDAM Tirtanadi Delitua and discuss the importance of monitoring these levels in maintaining the quality of water treatment.

The Importance of CaO Levels in Water Treatment

CaO levels in lime are crucial in water treatment as they function in the deposition of solid substances and control water pH. The optimal range of CaO levels in lime is between 60% to 70%, as suggested by the ISO standard 15-2049-1994. If the CaO content drops below this threshold, it can affect the effectiveness of the water treatment process, making it essential to monitor and maintain these levels.

Methods of Determining CaO Levels

The titration method using standard NaOH solutions and phenolphthalein indicators is commonly used to determine CaO levels in lime. This method has good accuracy in measuring the CaO content, making it a reliable choice for monitoring purposes. In this study, the CaO levels obtained ranged from 64.57% to 63.97%, which is within the limits set by the ISO standard.

CaO Level Analysis

The decrease in CaO levels over time can be caused by several factors, such as changes in the quality of lime raw materials or environmental conditions that affect the stability of compounds in lime. It is essential to understand the cause of decreased CaO levels to ensure that the water treatment process remains effective and safe for consumers. The preparation of periodic monitoring programs to check CaO levels in lime will be very helpful in maintaining the quality of water treatment.

The Need for Further Research

While the CaO levels in lime used in PDAM Tirtanadi Delitua remain within the limits suggested by international standards, further attention is needed to understand the cause of decreased CaO levels and ensure that the water treatment process remains effective and safe for consumers. Conducting more in-depth testing of the composition of the lime used can help PDAM Tirtanadi Delitua choose raw materials that are more optimal and according to needs.

Conclusion

In conclusion, this study shows that the levels of CaO in lime used in PDAM Tirtanadi Delitua remain within the limits suggested by international standards. However, further attention is needed to understand the cause of decreased CaO levels and ensure that the water treatment process remains effective and safe for consumers. Applying the appropriate monitoring steps will be very helpful in maintaining the quality of water produced.

Recommendations

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

Conduct periodic monitoring programs to check CaO levels in lime.
Conduct more in-depth testing of the composition of the lime used.
Choose raw materials that are more optimal and according to needs.
Understand the cause of decreased CaO levels and take necessary actions to maintain the effectiveness of the water treatment process.

Future Directions

Future studies can focus on the following areas:

Investigating the effects of changes in lime raw materials on CaO levels.
Studying the impact of environmental conditions on the stability of compounds in lime.
Developing more accurate and reliable methods for determining CaO levels in lime.

By understanding the importance of CaO levels in lime and monitoring these levels, PDAM Tirtanadi Delitua can ensure that the water treatment process remains effective and safe for consumers.
