With the EZ7200 analyzer it is possible to measure Volatile Fatty Acids and Alkalinity in to or from your anaerobic digester in real time.

It is well known that The VFA/ALK ratio can help you prevent damaging or killing the bacteria in an anaerobic digester.

Such an “overfeeding” event can lead to tremendous costs for the operator of a digester. Underfeeding of the digester can lead to sub-optimal gas production or sludge processing. By monitoring the concentration of VFA and Alkalinity the feeding process of the digester can be optimized and potentially gas production can be increased.
