Biogas Production
with Xylem
Converting waste streams from agricultural and food production, as well
as effluents from industrial and municipal wastewater treatment plants,
into biogas is good for the environment, and when done efficiently,
enhances bottom line.
The substrates for biogas production must be kept moving in the fermentation process, as well as in
storage. Tank contents must be mixed to prevent both floating and settling of the substrates, to maintain a
homogeneous blend. These substrates are often a combination of fibrous, low density material and heavier
materials, two extremes that need to be maintained in suspension. Pumps must be capable of passing and/or
chopping substrates without clogging, for a reliable, consistent feed.

Whether processing manure, silage, wastes from food processing, or even recovery of food residual from
restaurants or residential homes, waste streams are rich in energy potential. Biogas production turns these
waste streams into assets, creating renewable sustainable energy sources at both local and national levels, while
reducing gas emissions linked to climate change.
Anaerobic digestion is a natural process, and relatively simple in concept. However, producing biogas efficiently
requires effective pumping and mixing of often difficult substrates.
