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.

basic information
- Not affected by carbonates. Direct titration method without volatile fatty acids. - Low detection limit. - Continuous monitoring in the anaerobic early summer treatment process. - High operational rate enabling maximum methane gas production. - Monitoring of methane fermentation decline due to VFA accumulation and data transfer function. - Parameters: VFA, total alkalinity, P alkalinity. - Analysis of up to 8 streams is possible. *By simultaneously installing the Hack Ultra TOC/TN analyzer: BioTector, it is possible to control the acceptance from the upstream process based on measurement results within approximately 10 minutes.
