NS-Instruments - Model MultiTalent 109 -Methane Potential Biodegradation Analyzer
FromNS Instruments
Methanogenic potential (BMP) testing is a method for assessing the amount of methane produced from fermentation substrates. It provides crucial information for designing key parameters such as organic loading and residence time in biogas projects, as well as for optimizing fermentation strategies. By testing the BMP of organic wastes with different mixing ratios, important parameters of the co-digestion process of organic waste can be obtained.

This test, conducted using a small-scale batch fermentation reactor, measured trace gas yields under pre-defined anaerobic conditions with controlled temperature and mass transfer. The yields were then converted to ml-gas/g-vs-substrate under standard STP conditions. The methane degradation kinetic data obtained from the test also provided information on fermentation inhibition, such as hydrolysis rate limits. This data is of great significance for understanding biogas fermentation efficiency and process stability, guiding the digestion process, production optimization strategies, and investment return assessment of biogas projects.
Larger reactor volume: The larger the fermentation capacity, the smaller the impact of errors from other factors. Standardized fully automated testing: effectively saves time and labor. Standardized testing processes and data output, local touchscreen access and operation.
MultiTalent 109 is a new product specifically designed for the rapid evaluation of biogas or methane potential of materials, based on the software control logic and design philosophy of the flagship 203 model. It increases the fermentation bottle volume to 1 L (2 L optional for continuous feed and discharge) and reduces the number of fermentation bottles and product channels to 9. It is suitable for testing the fermentation potential of homogeneous substrates in biogas plants to determine engineering input levels, meeting the needs of project design units and factory laboratories for material screening and evaluation research, and helping researchers optimize engineering design and process operating parameters. The standardized testing process facilitates practical teaching. Anaerobic digestion technology, as a mainstream treatment technology for solid waste and high-concentration organic wastewater, plays a crucial role in pollution reduction and energy recovery. Addressing the prominent issues in the configuration of practical teaching equipment during the construction of new engineering disciplines, MultiTalent 109 and continuous feed operation simulation equipment such as Sekvent are used to arrange material methane production and toxicity testing to optimize process parameter design. This allows practical teaching to be integrated with real teaching products as much as possible, enabling students to understand the comprehensiveness, advancement, and cutting-edge nature of environmental engineering technology. Unattended testing capabilities enhance project processes. Fully automated unattended operation is crucial for users, so we`ve simplified the operation and maintenance process. After sample loading, MultiTalent can perform over 1500 hours of accurate unattended analysis from the start of the experiment. Real-time monitoring via the embedded processor and interactive touchscreen display allows users to observe experimental progress and prepare for post-experiment sample analysis or other operations. Ultimate precision measurement utilizes an ARM embedded processor, improving testing accuracy and stability. Broad testing coverage is suitable for the resolution of anaerobic fermentation. Advanced 9-channel parallel testing provides optimal experimental throughput. Real-time monitoring of gas production data during the reaction allows for pre-analysis of existing data even before the experiment is complete. A headspace overestimation calibration function corrects data based on headspace size and CO2 concentration estimates, providing more accurate and reliable methane production data. MultiTalent 109 is a universal platform for testing protocols of anaerobic biodegradability, methane potential (BMP), and stomatogenic activity (SMA). It conforms to the experimental procedures required by relevant international biodegradability testing standards, perfectly elucidating degradation kinetics. High-quality data results allow for comparison of data from different research institutions and laboratories worldwide.
