ABSTRACT:
An apparatus for separating contaminated waste water into a substantially uncontaminated homogeneous extract water portion and into a heterogeneous raffinate fluid portion. Upon being subjected to sufficient circular flow, in an environment emulating the action of a centrifuge, the heavier liquid and solid components are caused to gravitate out of the waste water. This apparatus is constructed with an elongated housing means which is preferably disposed between a water storage tank and fluid contaminant discharge device. Contained longitudinally within the elongated housing is a separator chamber having a portion of a frustoconically shaped centrifugation surface which directs the incoming waste water into a turbulent and circular pattern. As the waste water gains momentum during this centrifuge-like flow pattern, it abruptly strikes a substantially vertical impact plate which precipitates the forced separation of the impurities and contaminants from the waste water. The heavier extract component gravitates to a sump region located in the bottom of the housing, while the lighter raffinate fluid portion component rises into a raffinate separation region located in the top of the housing. A combination of baffle plates both promote the separation of the extract from the raffinate fluid portion and prevent the re-mixing thereof, once separation occurs. The accumulated extract portion is discharged through a drain at the bottom of the housing and raffinate fluid portion is discharged to the contaminant discharge device through an outlet located in the top portion of the housing.
