High-Efficiency Anaerobic Biofilm Reactor for POME Treatment

📊 Project Overview

Ecology Solution, in partnership with Universiti Tunku Abdul Rahman (UTAR) and Central Queensland University (CQU), has successfully piloted a 2000-liter anaerobic biofilm reactor for the sustainable treatment of Palm Oil Mill Effluent (POME). This project offers a scalable and compact alternative to conventional lagoon systems and aligns with Malaysia Sustainable Palm Oil (MSPO) standards.

🔄 Core Achievements:

  • 89.85% COD reduction at 13.3 days HRT

  • 74.5% TS and 77.0% TSS removal

  • Stable operation for 280 days

  • Biogas generation potential through efficient methanogenesis

🌍 Environmental Impact & Industry Significance

Palm oil mills in Malaysia generate vast volumes of POME, a high-COD effluent that must be treated before discharge. Traditional lagoon systems require high land usage and long retention times.

Our biofilm reactor:

  • Cuts treatment time by 30-40% compared to lagoon systems

  • Produces lower sludge volume

  • Improves biogas recovery

  • Operates under mesophilic temperature (38°C) for optimal microbial activity

🧬 Microbial Performance & Reactor Stability

The reactor maintained optimal pH (7.0–7.8), temperature, and microbial load (up to 36.5 g/L MLVSS). DNA sequencing showed strong microbial community structure, dominated by:

  • Anaerolineaceae: Hydrolysis

  • Syntrophomonas: Acetogenesis

  • Methanosaeta: Methanogenesis

These microbes worked synergistically to convert organic matter into methane-rich biogas while improving effluent quality.

🏢 Industrial Upscaling Potential

This 2000L pilot validates the reactor’s adaptability for full-scale operations. By maintaining high efficiency at 13.3-day HRT, the system offers a compact, modular alternative for palm oil mills with limited land.

  • Scalable to 10,000 TPD plants

  • Suitable for MSPO certification

  • Aligns with UN SDG 6, 9, 13
