Abstract
An apparatus for the separation of immiscible liquids from liquid influent has a containment vessel. An influent channel extends toward the bottom of the vessel so the influent is discharged vertically upward, a downwardly curved deflection plate is mounted above and aligned with the discharge end of the influent channel, and a plate with a downward slope from a central location extends toward the periphery of the vessel in a lower portion of the vessel than the deflection plate. This permits the influent to move radially outwardly thus slowing the influent and providing a residence time for gravitational separation of lighter immiscible liquids from the influent. A gap between the downward slope plate and the discharge end of the influent channel permits gravitational release of trapped immiscible liquids. A transfer tube, a sensor, and a pump are provided to pump the separated immiscible liquids out to a remote location. A suction conduit suctions heavier-than-water solids from the bottom of the vessel and an effluent channel channels the separated water to a remote location, such as a sewer.
