Chemical Composition

Parameter

Balance between acid production and buffering capacity.

Method

Analysed via titration after destillation.

Application

Quick diagnostic tool determining the health of the anaerobic digestion process. Helps operators adjust organic loading rate or feed composition before severe acidification occurs.

Parameter

Chloride content of sample (Cl^_)

Method

Spectrophotometric determenation of Chloride content.

Application

Water quality control, environmental impact, corrosion control.

Parameters

Concentration of the fatty acids: acetic acid, propionic acid, isobutyric acid, butyric acid, isovaleric acid, valeric acid, isocaproic acid, caproic acid, heptanoic acid, octanoic acid.

Method

Determination via gas chromatography.

Application

The spectrum of fatty acids can be used as a fingerprint for the stability and process control of anaerobic fermentation processes.

Parameter

Lactic acid

Method

Spectrophotometric determenation of lactic acid.
