A multi-directional flow gravity separator for separating a mixture of two immiscible fluids with different densities includes an elongated generally vertical tank, in which the mixture flows in a generally downward direction, and an effluent discharge tube through which the clarified effluent flows upward and out the tank. Alternatively, the separator includes an elongated vessel, or shroud, within the tank, through which the mixture flows in a generally upward direction before flowing downwardly in the tank; the clarified effluent is discharged from about the bottom of the tank. Alternatively, a separator includes both the elongated vessel and an effluent discharge tube. Alternatively, the vessel of a separator includes a coalescer; preferably, the coalescer results in an increased length of the fluid flow path through the vessel; most preferably, the coalescer is a helical spiraled vane, which results in a helical fluid flow path. In all embodiments, the lighter fluid is collected and discharged from the upper portion of the separator. In another aspect, a bi-directional flow coalescing device includes an elongated vessel and a coalescer, where the mixture is introduced near the bottom of the vessel and flows generally in an upward direction through the coalescer; most preferably, the coalescer is a helical spiraled vane, which results in a helical fluid flow path.
