Determining Phosphate and COD Levels in Wastewater Treatment Process of PT Sinar Oleochemical International (PT SOCI)

Introduction

Wastewater treatment is a crucial process in maintaining water quality and the surrounding environment. PT Sinar Oleochemical International (PT SOCI), a company engaged in oleochemicals, produces wastewater that requires special handling. In this context, monitoring the levels of Chemical Oxygen Demand (COD) and phosphate in PT SOCI wastewater is essential to ensure that the wastewater treatment process is effective. This article discusses the determination of phosphate and COD levels in the wastewater treatment process of PT SOCI.

Importance of COD and Phosphate Monitoring

COD is an indicator of water pollution by organic substances that can be oxidized microbiologically. This oxidation process consumes dissolved oxygen in water, which can threaten the life of water organisms. On the other hand, phosphate is a chemical compound found in wastewater that can trigger excessive algae growth (blooming algae). This phenomenon can cause a decrease in water quality, as algae can consume dissolved oxygen in water and produce toxins.

Methodology of COD and Phosphate Analysis

COD analysis is carried out by oxidation method using potassium dichromate (K2Cr2O7) in acid solution. The results of the analysis show that the COD concentration in PT SOCI wastewater is in the range of 20 mg/L - 38 mg/L. Phosphate analysis is carried out by the ascorbic acid method using a spectrophotometer at a wavelength of 880 nm. The results of the analysis showed that phosphate concentrations in PT SOCI wastewater ranged from 0.30 mg/l - 1.08 mg/L.

Comparison with Standard Wastewater Quality Standards

Based on the standard wastewater quality standards, the maximum COD concentration is 200 mg/l and the maximum phosphate concentration is 2 mg/l. The results of the analysis show that the concentration of COD and phosphate in PT SOCI wastewater still meets quality standard standards. This shows that PT SOCI has implemented an effective wastewater management system.

Routine Monitoring of COD and Phosphate Levels

Routine monitoring of COD and phosphate levels in PT SOCI wastewater is an important step in maintaining water quality and the surrounding environment. In addition, PT SOCI also needs to make efforts to prevent and reduce waste, such as the use of environmentally friendly raw materials, optimizing the production process, and the application of more sophisticated waste treatment technology. Thus, PT SOCI can play an active role in maintaining environmental sustainability and business sustainability.

Conclusion

In conclusion, the determination of phosphate and COD levels in the wastewater treatment process of PT SOCI is essential to ensure that the wastewater treatment process is effective. The results of the analysis show that the concentration of COD and phosphate in PT SOCI wastewater still meets quality standard standards. However, PT SOCI needs to continue monitoring COD and phosphate levels and make efforts to prevent and reduce waste to maintain environmental sustainability and business sustainability.

Recommendations

Based on the results of the analysis, the following recommendations are made:

Continue monitoring COD and phosphate levels in PT SOCI wastewater to ensure that the wastewater treatment process is effective.
Implement measures to prevent and reduce waste, such as the use of environmentally friendly raw materials, optimizing the production process, and the application of more sophisticated waste treatment technology.
Conduct regular training and education programs for employees on the importance of wastewater treatment and the need to prevent and reduce waste.
Collaborate with other companies and organizations to share best practices and technologies for wastewater treatment and waste reduction.

Future Research Directions

Future research directions include:

Conducting a comprehensive study on the impact of wastewater treatment on the environment and human health.
Developing more sophisticated waste treatment technologies that can effectively remove COD and phosphate from wastewater.
Investigating the use of alternative raw materials that can reduce waste and improve the sustainability of PT SOCI's operations.

Limitations of the Study

The study has several limitations, including:

The study only monitored COD and phosphate levels in PT SOCI wastewater and did not consider other parameters that may affect water quality.
The study only analyzed wastewater samples from PT SOCI and did not consider wastewater samples from other companies or industries.
The study did not investigate the impact of wastewater treatment on the environment and human health.
