Refinery & Biodiesel Plant – Tarjun
130 m³/day wastewater treatment plant was delivered by PT Lautan Organo Water for an integrated refinery and biodiesel facility in Tarjun, Indonesia. Completed in 2020, the plant was engineered to treat wastewater with an organic loading of approximately 2.5 tons COD/day, primarily originating from the biodiesel production process.
Due to the exceptionally high COD concentration of the influent wastewater, an Upflow Anaerobic Sludge Blanket (UASB) reactor was implemented as the primary biological treatment stage. The UASB system effectively reduces the organic load while providing a stable and energy-efficient treatment process for high-strength industrial wastewater.
Following anaerobic treatment, a Moving Bed Biofilm Reactor (MBBR) system was employed to further degrade residual organic contaminants and enhance overall treatment performance. This integrated anaerobic-aerobic treatment configuration ensures efficient COD removal, operational reliability, and compliance with environmental discharge requirements.
The project demonstrates PT Lautan Organo Water’s capability in delivering customized wastewater treatment solutions for complex industrial applications with challenging wastewater characteristics and high organic loading conditions.
