Foam formation in full-scale biogas plants processing biogenic waste

Small Scale Biogas plants for the treatment of Food Waste

Farm-scale Biogas Plants

In Germany there are about fifteen years of experience in the planning and construction of farm-scale biogas plants. In the meantime, approximately 1,600 biogas plants are in operation on farms. This is primarily due to investment funding and payment for each kWh delivered to the public energy grid. In general, three different kinds of digester types are in use for anaerobically treating manure...

Comparative review of foam formation in biogas plants and ruminant bloat

This review gives an overview of the current knowledge concerning the problem of foam formation in the process of anaerobic digestion in biogas plants that utilize renewable resources or biogenic waste material for biogas production. Process upsets in biogas production induced by foam formation can have a negative impact on the efficiency of biogas plants. The foam can block gas pipes and cause...

Foam formation in biogas plants caused by anaerobic digestion of sugar beet.

The use of sugar beet in anaerobic digestion (AD) during biogas production can lead to process upsets such as excessive foaming in fermenters. In the present study, foam formation in sugar beet-fed digestates was studied in foaming tests. The increasing disintegration grade of sugar beet was observed to have a promoting effect on foaming in the digestate but did not affect the biogas yield. Che...
