The benefits of online measurement of VFA and its principles.

Monitoring VFA (Volatile Fatty Acids), an important parameter in anaerobic digestion.

VFA is volatile, making it difficult to measure in the lab. Moreover, online measurement is often considered impossible, but the Hack 4 Ultra has the optimal VFA meter, the EZ series, to solve this challenge. With the VFA meter EZ series, you can automatically measure pH, alkalinity, and volatile fatty acids. Additionally, it has an automatic cleaning function, which addresses common issues encountered during online measurement, such as "high SS and residues in the sample." By introducing this device, you can reduce the risk of acidification in the methane fermentation layer and optimize the process.

• Analytical Equipment and Devices

Real-time VFA monitoring device to maximize the efficiency of methane fermentation in anaerobic digestion.

The online VFA meter EZ7200 series is a high-performance online titration device designed for monitoring wet anaerobic digestion tanks. It proposes a new management method for medium to large-scale anaerobic digestion processes. In biomass power generation, industrial wastewater, and sewage treatment, the anaerobic treatment of wastewater and sludge in fermentation tanks involves the breakdown of very complex organic carbon compounds, which presents challenges. Real-time measurement of VFA (volatile fatty acids) is effective for stabilizing the methane fermentation tank in anaerobic treatment. Relying solely on pH measurement and sampling can make it difficult to monitor the conditions inside the fermentation tank, depending on the timing. The ideal pH value inside the fermentation tank is said to be between 6.5 and 7.5, but measuring pH alone is not sufficient; adequate buffering capacity [total alkalinity TAC (also referred to simply as alkalinity)] is necessary to compensate for changes in acid concentration. By continuously monitoring VFA, which are intermediate substances during methane fermentation, it contributes to maintaining a more stable fermentation tank and maximizing gas production. By conducting online measurements at 10-15 minute intervals, it becomes possible to anticipate various events within the digestion tank in advance.
