More Details

Substrate sample collected from biogas digesters or the digestate (output from the digester) entails an array of information pertaining to the degree of stability of the digestion process. Thus, the provided package testing of the substrate from the biogas plant can be a fair indicator of the overall performance characteristics of a running biogas plant. The package has been carefully designed to delicately analyze the substrate and cater to the right information and recommendation needed to optimise the performance of your plant. The package includes the following tests:

A. DM/oDM-The TS or DM content in a digester can be used as an indicator of the viscosity of the fermentation broth in the reactor. Another feedstock parameter, the organic dry matter (oDM) represents the organic fraction which is the source from which biogas is produced and is therefore very important. ( refer individual test for more information)

B. NH4-N- Measuring of NH4-N helps to detect rapid changes in ammonia concentrations which can provoke process inhibition.( refer individual test for more information)

C. FOS/TAC-The alkalinity ratio is a two-point titration measurement which determines the ratio of the intermediate alkalinity (IA) over the partial alkalinity (PA). In German literature, the parameter is called FOS/TAC.

D. VFA spectrum-Various acids (Acetic Acid, Propionic Acid, Butyric acid, Valeric Acid, or branched isomers of them ) are produced during further degradation of simple sugar, amino acids, and long-chained fatty acids, which in turn are derived from carbohydrate, protein, and fatty components respectively in the feedstock.
