Automatic titration device measures the ratio of total inorganic carbon salts (TAC) to free organic acids (FOS) in the bioreactor using a titration device to optimize methane production.

Optimizing Methane Production in Biogas Fermentation Tanks: Measurement of FOS/TAC Ratio Using a Titration Device Application Using the Metrohm Automatic Titrator Eco Titrator Monitoring the ratio of total inorganic carbon (TAC) to free organic acids (FOS) is crucial for optimizing the fermentation process within a bioreactor (biogas fermentation tank). Maintaining a stable optimal TAC/FOS ratio within the bioreactor maximizes methane production, thereby maximizing the profitability of the biogas plant. This white paper (WP) provides a detailed explanation of the chemicals involved in the biogas production process and the method for measuring the FOS/TAC ratio using a titration device.
