The Effect of Volumetric Flow Rate of Static In-Line Mixer Feed on Bioreactor Performance in Making Biogas from Palm Oil Liquid Waste Scale Pilot Plant

Introduction

Indonesia, the second largest producer of Crude Palm Oil (CPO) in the world, has a significant potential in the biogas industry. One of the main factors contributing to this potential is Palm Oil Mill Effluent (POME), a liquid waste resulting from the oil palm processing process. POME has a high organic content that can be converted into biogas through the anaerobic fermentation process. The process of making biogas is carried out in thermophilic conditions using a recycled sludge by 34% through four tanks, namely the preparation tank, mixing tanks, bioreactors, and gravitational thickening tanks.

The Importance of Mixing Tanks in Biogas Production

Mixing tanks play a crucial role in the biogas production process, equipped with mixers, impellers, and baffles to ensure an even mixture. However, to increase production capacity, it is necessary to adjust the specifications of the mixing tank, especially in the size and type of stirrer. One promising solution is the use of static in-line mixers, which is designed to improve the efficiency of mixing. Static in-line mixers are designed to provide a high level of mixing efficiency, which is essential for the biogas production process.

The Objective of the Study

This study aims to evaluate the ability of static in-line mixers in mixing POME from pre-conquering tanks with recycled sludge from gravitational thickening tanks, as well as to see the effect of this mixing on bioreactor performance and biogas production. The parameters measured in this study include Total Solid (TS) and Volatile Solid (VS), pH, M-alkalinitas, and Chemical Oxygen Demand (COD). The quality of mixing will be evaluated by comparing TS and VS data from the tank of mixing or static in-line mixing with theoretical data obtained from regression analysis.

The Methodology of the Study

The study was conducted using a pilot-scale bioreactor, which was equipped with a static in-line mixer. The POME was fed into the bioreactor through the static in-line mixer, and the mixing process was evaluated using regression analysis. The parameters measured in this study include TS and VS, pH, M-alkalinitas, and COD. The quality of mixing was evaluated by comparing TS and VS data from the tank of mixing or static in-line mixing with theoretical data obtained from regression analysis.

The Results of the Study

The results of the regression analysis show a good R value (0.9-1) with respective results a. (0.978), b. (0.976), c. (0.992), d. (0.989). These numbers indicate that the mixing carried out by the Static In-Line Mixer is very efficient and reliable. The results of the study also show that the use of static in-line mixers can improve bioreactor performance and biogas production.

The Conclusion of the Study

This study highlights the potential of POME in biogas production and provides valuable insight into the use of efficient mixing technology to improve bioreactor performance. The implementation of this technology is expected to help optimize the biogas production process, thereby increasing the sustainability and efficiency of the oil palm processing industry in Indonesia.
