<p>A biological rotor for biomass treatment in a sewage treatment plant is erected from sector shaped packs removably attached between spider-like support assemblies each of which comprises a ring and radial channel-shaped arms. The packs include support members. One of the support members has its ends located in the channels of the arms and the other support members are clamped to the ring. A separator plate can be built up from sections formed in each pack.</p> |
