Abstract: Separating a multi-phase mixture influent even during excessive flows of specific phases. The dynamic phase separator includes a chamber divided into two regions by an inner wall disposed radially inward relative to an outer wall. A gross separation region is defined between the inner wall and the outer wall, while a fine separation region lies inside an area defined by the inner wall and top of the chamber. Influent to be separated is fed through an inlet into the gross separation region. A plurality of porous disks are mounted to a rotatable shaft and disposed in the fine separation region. The outer and inner walls are separated by a predetermined distance sufficient to allow for adequate rotational velocity of incoming tangential flow of the influent and dwell time sufficient for natural separation of lighter phases from heavier phases within the gross separation region.

Abstract: A nonclogging rotary disk filter is disclosed. The invention has relief holes provided in rotatable disks such that oil, other liquids, and gases may be separated from a liquid while the discs are rotated at high speeds. The relief holes are located close to the rotatable shaft supporting the disks. When the disks are rotated at high speeds, ligher liquids, oil, and gas bubbles tend to migrate to the area near the shaft which has relatively low centrifugal forces. In a gravitational field, the relief holes allow the lighter liquids, oil, and gas bubbles to migrate upwardly through the disks for removal. The disks are rotated fast enough to establish a barrier layer in a liquid over a working area of the disk surface having a surface velocity greater than 15 feet per second.
