Abstract: A waste water treatment system includes a first stage oil separator having a plurality of conically shaped members disposed inside an enclosure. The conically shaped members are preferably made of polypropylene. Oil within the waste water coalesces upon contacting the conically shaped members. Waste water is circulated in vortical flow paths between the conically shaped members to lengthen the flow path of the waste water between the members thereby promoting coalescence of oil. A second stage oil separator involves a bead pack container unit filled with polypropylene beads through which waste water passes to remove residual oil and debris from the waste water coming from the first stage oil separator.

Abstract: An apparatus and a method for separating heterogeneous mixtures of at least two components, including immiscible liquid/liquid solutions as in separating oil from water, or solid/liquid mixtures as in separating solid waste from sewage water. The apparatus allows for pre-separation before the influent enters the separator proper. The apparatus and a method provide for heterogeneous solutions to enter the apparatus at the same end at which the effluent is removed and in which an amount of separation occurs prior to the formal entrance to the separator tank. The tank geometry and structure are such that liquid/liquid solutions as well as solid/liquid solutions may be separated. The geometry and structure of the tank are also such that there is significant reduction in flow turbulence, laminar flow is utilized, and significant performance degradation in the purity of the resulting effluent are not seen as fluid flow continues.

Clarified liquid is withdrawn from the free settling region. Liquid is allowed, in at least the compaction region, to move upwardly along at least one upwardly inclined pathway, while at least partially protected from settling solid particles. Slurry is withdrawn from the compaction region.

Abstract: A compact gravitational oil-water separator particularly adapted for use in small drainage systems in order to avoid pollution to the environment is provided with a plurality of separating components housed within a tank. More specifically, these components include a baffle member which provides initial separation of an incoming oil-water flow stream and distributes the flow substantially across the entire width of the tank. After the flow impinges the baffle member, the flow is directed downward towards a sediment bucket which captures any large particles separated from the flow and then the flow is directed upwardly at an angle through a coalescer unit. After exiting the coalescer unit, the flow is guided over a separation plate and then is re-directed, in a reverse direction, to an inlet opening of an outlet flow passage. By reversing the fluid flow, substantially the entire tank is utilized in the separation process.

Abstract: The energy of liquid and solids flowing in a basin toward a clarifier section is substantially reduced before the liquid and solids enter the clarifier section. The basin is provided with an inlet wall having an inlet opening adjacent the top thereof. A sheet having an arcuate, reverse "C" shape is mounted across the inlet opening with the open side of the "C" facing the inlet wall to receive the liquid and the solids therefrom.

The helically flowing paths of liquid and solids are discharged into the basin spaced from the side walls of the basin, which further dissipates some of the kinetic energy of the liquid and the solids.

Abstract: A separator for immiscible fluids and particulate matter of differing denies provides a plurality of stages of fluid flow velocity reduction by change of cross-sectional areas between a plurality of flow regions (e.g. conduits and chambers) and separates a fraction of the introduced fluid or suspended particulate matter at each change of velocity whereby flow velocity may be reduced to a degree greater than accounted for by the change of cross-sectional area from stage to stage when significant amounts of materials to be separated are present in the input fluid. Further, a substantial effective length is provided, relative to the footprint of the separator. This length and gradual slowing of the fluids therein provides generally laminar flow and low turbulence. By doing so, overall volume of the passive separator is reduced and separation efficiency is substantially improved.
