DEVICE FOR SEWAGE TREATMENT Russian patent published in 1995 - IPC

FIELD: chemical engineering. SUBSTANCE: disk 5 is mounted on drive shaft 3. Disk 4 is set up on resilient prop 19 on disk 5. Not rigid conical partitions 7 and 8 are attached by their smaller bases to disks 4 and 5 forming ring-shaped slot 9 between them. Slot 9 is in communication through chamber 6 with branch pipe 2 for the sewage feeding. Flexible membrane 10 with resilient crimped reservoir 11 placed under it is mounted under partition 8. Reservoir 11 is in communication with source 12 of the pulsing feed of the working agent which arouses the shiftings of flexible membrane 10 and the contactless influence through the rotating air flow around partition 8. It enhances the quality of the sewage treatment in ring-shaped slot 9 and promotes the petroleum detachment from partition 8 resulting in its vibration. The installation of disk 4 on resilient prop 19 on disk 5 excludes the seal of ring-shaped slot 9 by solid inclusions of the drainage. EFFECT: enhanced quality of the sewage treatment. 3 dwg
