摘要

A rotating device is described for the centrifugal sludge lifting in bioreactors, particularly suitable for carrying out biological processes under mixing conditions presenting extremely low shearing forces. The device comprises a hollow vertical rotating shaft (3) and at least one rosette (4) of horizontal tubular arms solidly connected with said vertical shaft (3).
