Each stage is oriented transversely the shaft and has plurality assemblies. assembly number disks. disks comprises multiple concentric arcuate segments. segments are provided two generally radially extending edges, circumferential edges extend between legs, front face back face. Posts from faces for stirring offering site adherence biomass suspended Connecting members interconnect adjacent optionally define flow channel therebetween. First second engagement features also one surfaces enable joined.
