Types of Biogas Digesters and Plants - energypedia.info

Choosing a right biogas digester is a very important while constructing a biogas plant. From the standpoint of fluid dynamics and structural strength, an egg-shaped vessel is about the best possible solution. This type of construction, however, is comparatively expensive, therefore, its use is usually restricted to large-scale sewage treatment plants. The Chinese fixed-domedesigns are of similar shape, but less expensive. The hemispherical CAMARTEC design is optimized in structural strength, but
