Abstract:

Pertamina EP Pertamina EP Donggi Matindok Field realizes that sustainable development activities need to pay attention to environmental aspects, including efforts to reduce the load of water pollution. In the production process at Matindok Central Processing Plant (CPP), by-products are produced in 2 forms: solid sulphur and wastewater from the Biological Sulphur Recovery Unit (BSRU). Sulphur solids carried in wastewater can cause blockages known as plugging in injection wells and disrupt the production process. This study aims to reduce the water pollutants by integrating a nanofiltration membrane in the Bleed Water Treatment (BWT) to reduce the Total Dissolved Solid (TDS) content in wastewater after being processed in the After Treatment Unit (ATU). The experimental results showed a significant decrease in TDS values after nanofiltration membrane integration, from ≥14,000 mg/L to <4,000 mg/L. This program succeeded in reducing water pollution in 2023 by 272.68 tons of TDS.
