Determination of Phosphate Levels in Water Recovery Boiler Feed Water with UV-VIS Spectrophotometry Method at PT Toba Pulp Lestari, Tbk-Porsea

Introduction

The pulp and paper industry is a significant contributor to the global economy, with the production of paper and paper products being a vital part of our daily lives. However, the industry also has a significant impact on the environment, with the management of water recovery boiler feed water being a critical aspect of maintaining operational efficiency and preventing damage to equipment. At PT Toba Pulp Lestari, Tbk located in Porsea, controlling phosphate levels in boiler feed water is one of the main focuses. Phosphate is added to boiler feed water to prevent corrosion and sediment formation in the boiler wall. Chemical processes involving calcium and magnesium in water boilers can cause this problem if phosphate levels are not well maintained.

The Importance of Phosphate Levels in Boiler Feed Water

Phosphate levels in boiler feed water play a crucial role in maintaining the operational efficiency of the boiler. Inappropriate phosphate levels, both too high and too low, can cause corrosion and sediment formation. As a result, the hot drainage in the boiler is not optimal, which makes the energy needed to produce steam increases. This can lead to a significant increase in operational costs and a decrease in the overall efficiency of the boiler. Therefore, it is essential to monitor and maintain phosphate levels within the specified limit to prevent these problems.

The UV-Vis Spectrophotometry Method

The UV-Vis spectrophotometry method is an effective technique for measuring the concentration of solutes in water, including phosphate. In this technique, ultraviolet and visible light is used to measure absorbance of a solution containing phosphate. Each chemical compound has a certain wavelength that can be absorbed, so that by knowing the absorbance at the wavelength, we can calculate the concentration of existing phosphate. The UV-Vis spectrophotometry method is widely used in various industries, including the pulp and paper industry, due to its accuracy and reliability.

The Results of the Analysis

Based on the results of the analysis conducted, measurable phosphate levels range between 5-8 ppm, which is still within the safe range according to company standards. These results indicate that the management of phosphate levels has been carried out well, although there is still space for improvement so that phosphate levels can be closer to the ideal number, which is 10 ppm. The results of the analysis also show that the UV-Vis spectrophotometry method is an effective technique for measuring phosphate levels in boiler feed water.

The Importance of Maintaining Phosphate Levels

Maintaining phosphate levels within the specified limit is crucial in maintaining system balance and reducing the risk of damage to the boiler. If the phosphate level is too low, the risk of corrosion increases, whereas if it is too high, it can cause deposition that results in blockages and decreased efficiency. Therefore, monitoring regularly and the application of appropriate actions based on the results of the analysis is very important in the operation of this industry.

The Impact of Phosphate Levels on Sustainability

In the context of sustainability, maintaining phosphate levels within the specified limit not only prevents damage to equipment, but also contributes to energy efficiency and reduces operational costs. In an era where efficiency and sustainability are increasingly considered, strict research and management in terms of phosphate levels will have a positive impact on the operational sustainability of PT Toba Pulp Lestari, Tbk and the surrounding environment. Therefore, it is essential to continue monitoring and maintaining phosphate levels within the specified limit to ensure the sustainability of the industry.

Conclusion

In conclusion, the determination of phosphate levels in water recovery boiler feed water using the UV-VIS spectrophotometry method is an important step that functions as a controller in industrial processes, as well as a role in optimizing the use of resources and maintaining environmental sustainability. The results of the analysis conducted show that the management of phosphate levels has been carried out well, although there is still space for improvement. Therefore, it is essential to continue monitoring and maintaining phosphate levels within the specified limit to ensure the sustainability of the industry.
