DEVICE FOR SEWAGE CLARIFICATION AND DEHYDRATION OF SLIME Russian patent published in 2005 - IPC

FIELD: production of devices for sewage clarification.

SUBSTANCE: the invention is pertaining to production of devices for sewage clarification and may be used for clarification of sewage from coarsely dispersed impurities in a centrifugal field and simultaneous dehydration of the formed slime. The device contains a pressure hydrocyclone and a nutsch filter mounted in its lower part. In the lower part of the device they provide for installation of an ejector creating rarefaction in the body of the nutsch filter due to a residual pressure after a pressure hydrocyclone in the pipeline of the clarified sewage. In the body of the nutsch filter there are a perforated conical bottom and a filtration element. The technical result is intensification of processes of dehydration of a slime at a sewage clarification in pressure hydrocyclones.

EFFECT: the invention ensures intensification of processes of dehydration of a slime at a sewage clarification in pressure hydrocyclones.
