DEVICE FOR SELECTING PROTEINS FROM SEWAGE Russian patent published in 1995 - IPC

FIELD: environment protection; sewage purification. SUBSTANCE: device has casing, driven shaft mounted in the casing together with two disks placed one above another and mounted on the shaft and flexible perforated conic partition freely attached to the upper disk. The device also has additional disks having flexible perforated conic partitions freely attached to the disks with their smaller bases. The additional disks are mounted over the main ones forming coaxial ring-shaped clearances between the partitions. The upper disk with the first partition, when counting in the direction of sewage flow, is rigidly mounted on the driven shaft. The rest of the disks together with the partitions attached to them are mounted to be relatively moveable in axial direction by means of elastic supports. EFFECT: enhanced effectiveness in removing sewage proteins by using centrifugal forces. 3 dwg
