In biogas plants, the quality of digestate separation is one of the factors that most influences the energy yield and overall manageability of the process. The centrifugal decanters developed by CBB Decanter offer reliable and high-performance solutions to optimize this critical phase, improving the quality of the output flows and contributing to the stability of the entire plant.
The solid-liquid separation of the digestate allows us to obtain a drier solid fraction, easier to handle and exploit as a soil improver, and a liquid part with more homogeneous characteristics, which simplifies storage and agronomic distribution operations. This translates into greater operational efficiency and a more rational use of the resources produced by the anaerobic digestion process.
The CBB Decanters for biogas are designed to work continuously even in the presence of digestates rich in fibre, with variable loads or with high viscosity, typical of anaerobic processes fed with different matrices. The automatic regulation systems allow the machine’s behavior to be quickly adapted to the real conditions of the plant, maintaining the quality of separation constant over time.
