Determining Phosphate Levels in Wastewater: A Crucial Step Towards Environmental Protection

Introduction

Phosphate is a vital element for plant growth, but its presence in excess can have devastating effects on the environment. In wastewater, phosphate can be found in various forms, including orthophosphate, polyphosphate, and organic phosphate. The determination of phosphate levels in wastewater is essential to prevent eutrophication, which can lead to a decrease in water quality, fish death, and disrupt the balance of the ecosystem. In this article, we will discuss the determination of phosphate levels in wastewater using the UV-Visible spectrophotometer at PT. Sucofindo Medan.

The Importance of Phosphate in Wastewater

Phosphate is a polyatomic ion consisting of one phosphorus atom and four oxygen atoms. The element of phosphorus in phosphate is very important for plant growth. Phosphate serves to stimulate root growth, accelerate the flowering process, and help cook seeds and fruit. In water, phosphate can be found in various forms of compounds, including orthophosphate, polyphosphate, and organic phosphate. The composition of this phosphate can be in the form of dissolved, suspended, or bound in the cell of the organism.

At PT. Sucofindo Medan, phosphate levels in wastewater have been analyzed using UV-Visible spectrophotometry with a wavelength of 880 nm. The analysis showed that the phosphate level in upstream wastewater was around 0.227 mg/l, while downstream reached 1,837 mg/l. This difference indicates an increase in phosphate concentration in wastewater after going through a particular process.

The Impact of Excess Phosphate on the Environment

Excess phosphate in the body of the water can cause eutrophication, which is a process in which excess nutrition causes excessive algae growth. This can result in a decrease in water quality, fish death, and disrupting the balance of the ecosystem. Therefore, it is essential for companies such as PT. Sucofindo to routinely analyze phosphate levels in wastewater to prevent negative impacts on the environment.

UV-Visible Spectrophotometry: A Reliable Method for Determining Phosphate Levels

UV-Visible spectrophotometry technique is a very effective method in determining phosphate concentrations. This process involves the measurement of absorbance of light at a certain wavelength, which in this case is 880 nm. By using calibration standards, phosphate levels in wastewater samples can be determined accurately. The presence of higher phosphate downstream shows the existence of pollution that needs to be overcome to maintain the quality of the environment.

The Results of Analysis

The results of analysis of phosphate content in wastewater at PT. Sucofindo Medan shows the importance of supervision of wastewater quality to prevent negative impacts on the environment. UV-Visible spectrophotometry technique with a wavelength of 880 nm has proven to be effective in determining phosphate levels. The company must continue to monitor and take steps to reduce the level of phosphate in wastewater so as not to interfere with ecosystems and public health.

Conclusion

The determination of phosphate levels in wastewater is a crucial step towards environmental protection. The results of analysis of phosphate content in wastewater at PT. Sucofindo Medan highlights the importance of supervision of wastewater quality to prevent negative impacts on the environment. UV-Visible spectrophotometry technique with a wavelength of 880 nm has proven to be effective in determining phosphate levels.
