Hydroitalia – Colsen is able to propose different technologies for the treatment of the digestate, in order to define the most appropriate solution based on the specific situation and requirements of the Client.
The first stage for the treatment of the digestate produced from the anaerobic digestion is the separation by means of decanter or press. The by-products so obtained are the liquid fraction of the digestate with an high content of ammonia nitrogen and the solid fraction of the digestate which concentrates the majority of the organic solid content of the digestate.
