FOS / TAC – an important parameter for fermentation processes in biogas plants
An important parameter for the assessment of the fermentation process of modern biogas plants is the so called FOS / TAC value. The TAC (= Totales inorganic carbonate, also known as lime buffer) obtained by the titration of 20 ml of a centrifuged fermenter sample to pH 5.0 with 0.05 mol / l sulfuric acid. The FOS (= Volatile Organic acids) is determined by titration of the same sample to pH 4.4. The two values obtained in ml are used in two empirically derived formulas:
TAC = ml H2SO4 to pH 5.0 × 250
FOS = (ml H2SO4 from pH 5.0 to pH 4.4 × 1.66 – 0.15) × 500
Also another sample volume than 20 ml can be considered. From the values of both results of the FOS / TAC value is calculated. This method with all parameters and calculation formulas is stored as a standard method to TitroLine® 5000 and can be used directly.
