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: An oil water separator is disclosed having a vertical, cylindrical tank with a plurality of corrugated, oleophilic plates. A corrugated diffusion baffle is located adjacent an oil-water mixture inlet to remove the larger particulate material from the mixture and to cause coalescing of the larger oil droplets. The flow of the oil-water mixture proceeds generally in a vertical direction and passes between the corrugated plates to cause further coalescing of the oil droplets. A separate oil channel directs the coalesced oil to an upper portion of the tank. The clarified water then passes downwardly to a clean water outlet. A second coalescing unit may be located upstream of the clean water outlet to further coalesce and remove the smaller oil droplets. In this case, a second oil relief channel directs these coalesced oil particles to the upper portion of the tank, from which the oil may be removed.

Abstract: A fluid transfer apparatus for transferring gasoline, for example, to a bottom loading tank truck wherein a standpipe, rotatable about its vertical axis, is journalled at its upper end on an overhead support so that a rotary gland swivel at its bottom need be designed to support only the weight of the apparatus without having to resist bending moments. An articulated conduit assembly and counterbalance are mounted on the standpipe and rotate therewith throughout complete rotations about the vertical axis.
