Biodiesel Plant – Duri
We successfully delivered and commissioned a 180 m³/day wastewater treatment plant for a biodiesel factory in Duri, with a design organic loading of 3.6 tons COD/day.
Given the wastewater’s high concentration of oil and grease, the treatment system incorporates an Oil & Fat Separator followed by a Dissolved Air Flotation (DAF) unit as a robust pre-treatment stage to effectively reduce FOG content before entering the biological treatment.
The biological treatment train combines Moving Bed Biofilm Reactor (MBBR) and Conventional Activated Sludge (CAS) technologies to achieve efficient organic pollutant removal. To further polish the effluent and meet water reuse requirements, a Membrane Bioreactor (MBR) system was implemented for advanced COD reduction and stable effluent quality.
This integrated treatment solution enables reliable wastewater management while supporting the client’s objective of effluent recycling and sustainable water utilization within the biodiesel production facility.
