VWS Italia anaerobic plants for the production of biogas from biomasses have been developed utilising the best available technologies according to requirements such as yield, operational continuity and reliability.

Anaerobic plants specifics concern:

• the high biomasses mixing;
• the reactors volumetric ratios (diameter and height) to facilitate mixing and to avoid segregation, stratification and solids aggregation phenomena;
• the increase in the anaerobic sludge residence time compared to the hydraulic residence time;
• the external management, easy to maintain, of all the equipments; the use of gasometers to assure the adequate biogas quantity at constant pressure;
• a strong hydrolysis phase before the anaerobic digestion aimed at making the biomasses more degradable.
