A waste oil handling apparatus features a tank with draining compartments for receiving waste oil containers in inverted and elevated positions above the tank floor. Multiple drain ports communicate with the tank interior at different elevations relative to the floor for draining accumulated contents of varying density that have gravitationally separated into distinct layers at those elevations. The ports feature adjustable fittings for adjusting the levels from which the layered contents are drawn through the ports from the tank interior. The tank has a large cleanout access by which personnel can access the tank interior for thorough cleanout. The compartments are organized into one or more troughs, each having a pivotal lid thereon. Lift brackets under the floor enable lifted transport of the tank by pallet jack or forklift.

A separation apparatus includes: a partitioning member inside a separation tank, includes erect and transverse portions, and partitions the tank into inflow and outflow regions of a liquid; an inlet of which a lower level is set to be lower than an upper end of the erect portion and an upper level is set to be higher; a screen in the erect portion along a flow direction of the liquid; a swirling inducing member in the erect portion intersecting with the flow direction of the liquid; a screen in the transverse portion; a dividing member dividing the liquid flowing in from the inlet into flows along side walls of the separation tank; a retaining member at a downstream side in the flow direction and retains the substance having the specific gravity less than that of the liquid; and an outlet through which the liquid flows out from the outflow region.

Removing sediment from storage tanks without physically entering the tanks. More specifically, embodiments are directed towards inserting fluid into the storage tank via a liquid return line and injecting air into the storage tank via an air injection line to suspend sediment, draining and filtering the sediment, and returning the filtered fluid back into the tank via the liquid return line.

A method of concentrating sediment in a water tank involves attaching a vortex inducing device to an opening through the roof of the tank between the central vertical axis and the side walling of the tank. The device has a device inlet which narrows to a device outlet. The device outlet is orientated such that, water flowing out via the device outlet induces a vortex within the pooled water, thereby causing sediment to collect centrally on the floor of the tank.

A mechanical separator for separating a fluid sample into first and second phases within a collection container is disclosed. The mechanical separator may have a separator body having a through-hole defined therein, with the through-hole adapted for allowing fluid to pass therethrough. The separator body includes a float, having a first density, and a ballast, having a second density greater than the first density. A portion of the float is connected to a portion of the ballast. Optionally, the float may include a first extended tab adjacent a first opening of the through-hole and a second extended tab adjacent the second opening of the through-hole. In certain configurations, the separator body also includes an extended tab band disposed about an outer surface of the float. The separator body may also include an engagement band circumferentially disposed about at least a portion of the separator body.

A cyclonic inlet diverter for initiating the separation of a multi-phase inlet fluid flow comprises an enclosed tubular body mounted crosswise within a larger separator vessel. The inlet diverter includes a splitter plate positioned within a center portion of the tubular body and configured to split the inlet flow into a first stream and a second stream, and a swirl plate positioned on each side of the splitter plate with angled surfaces configured to increase the cyclonic motion of the first and second streams within the tubular body. The inlet diverter further includes elongate apertures formed through bottom sidewall portions of the tubular body on each side of the splitter plate, an axial aperture formed through opposing end caps of the tubular body, and at least one radial aperture formed through lateral sidewall portions of the tubular body proximate each opposing end cap.

The system for a continuous dewatering recirculating for removing particulate such as coal combustion residue from a water stream. The system includes multiple dewatering and recirculation containers, each having a submerged flight conveyor and lamella settlings plate located therein, at least one dewatering and recirculation container receives ash water stream overflow.

Disclosed is a sedimentation tank system including high-rate filtration part and being capable of primary treatment of sewage and wastewater, flow rate adjustment, and treatment of wetweather flow. According to an aspect of the present disclosure, there is provided a sedimentation tank system for removing solids in an influent sewage and wastewater, the sedimentation tank including a filtration part which includes a filter medium and removes solids in the influent sewage and wastewater, a sedimentation tank with a water gate formed at a predetermined height to store sewage and wastewater flowing over the water gate, and an outflow distribution channel that receives, from the filtration part, sewage and wastewater from which solids have been removed, and discharges the same to the outside of the primary sedimentation tank.

A particulate separator having a top baffle extends radially from an outer edge toward a vertical axis. The top baffle is positioned between an inlet port and a fluid outlet port. A radial flow channel extends below the top baffle from the outer edge toward the fluid outlet port. A series of baffles are positioned concentrically about the fluid outlet port and within the radial flow channel. The series of baffles include a first set of baffles having a top edge connected to a bottom surface of the top baffle and a bottom edge spaced below the top edge. A second set of baffles have a top edge spaced from a bottom surface of the top baffle. The first set of baffles are interleaved with the second set of baffles to define an alternating flow path along the radial flow channel from the outer edge to the fluid outlet port.
