摘要
The invention relates to a device and method for the anaerobic digestion of organic material to biogas by means of micro-organisms. The device and method intensify the anaerobic digestion process by using three separate reactors wherein a hydrolysis process, a first digestion process of a separated solid fraction, and a second digestion process of a separated liquid fraction take place respectively. Membranes and/or mechanical separation means are used to separate the fractions. This keeps the microorganisms, such as microbes, in the reactors. The obtained intensification of the anaerobic digestion process enables to operate with smaller tanks, which leads to lower building costs. The process also makes it possible to precipitate heavy metals for extraction.
