The reactor comprises a container containing substrate material, held firmly in place, for microorganisms, the liquid to be purified flowing past this substrate material. The substrate material consists of flat, straight, curved or tubular elements, and the direction of flow of the liquid is parallel to the largest-area surfaces of these elements.
