A sewage system component spray assembly is attached at a predetermined height above pumps in the interior of the component and has at least one nozzle for spraying liquid downwardly and generally tangential to a center of the sewage system component. Operation of the nozzle causes the liquid to disperse floating material on the sewage surface and creating a rotational flow around the center to direct such material to the pumps.

Assembly for dispensing a liquid, in particular a colorant for paint, comprising a container for holding a liquid, a pump, a valve, at least one dispense opening, and comprising or associated with a controller arranged to operate the pump and the valve to withdraw liquid from the container and to dispense liquid via the opening and to operate the pump and the valve to purge liquid from the pump to the container via the dispense opening.

Systems and methods for managing bulk material efficiently at a well site are provided. The disclosure is directed to a container support frame that is integrated into a blender unit. The support frame is used to receive one or more portable containers of bulk material, and the blender unit may include a gravity feed outlet for outputting bulk material from the containers directly into a mixer of the blender unit. The blender unit with integrated support frame may eliminate the need for any subsequent mechanical conveyance of the bulk material (e.g., via a separate mechanical conveying system or on-blender sand screws) from the containers to the mixer. As such, the integrated blender unit may be lighter weight, take up less space, and have a lower cost and complexity than existing blenders.

A production apparatus for a liquid containing gas bubbles includes a casing, a pump unit, and a gas bubble-mixing unit. The casing is provided with a main flow channel for a liquid, the main flow channel having a liquid inflow port and a liquid outflow port. The pump unit is disposed in the main flow channel and pumps the liquid to the liquid outflow port from the liquid inflow port. The gas bubble-mixing unit includes a first choke portion that is disposed in the main flow channel and has an inner diameter decreased and a gas supply channel that supplies the first choke portion with a gas.

An electrically driven oilfield blender system is configured to utilize electric motors as electric prime movers to prepare frac slurry and move the frac slurry to an oilfield pressure pumping system or pressure pumper that pumps the frac slurry into a subterranean formation. Each of the prime mover electric motors may operate at a fixed or constant rated speed and may be connected to a transmission that can drive a device such as a feed pump for a mixing tub or an auxiliary device at a variable speed. An electro-hydraulic motor start system includes an electric motor that powers a hydraulic pump. The hydraulic pump drives hydraulic motors that pre-rotate the prime mover electric motors to their rated speeds before they are energized.

A bioprocess vessel includes a flexible bag or substantially rigid container that defines an interior volume and having a bottom surface, the bottom surface being open or containing an aperture therein for the passage of fluid. A pump is secured to the bottom surface of the flexible bag or substantially rigid container. In some embodiments is secured directly to the flexible bag or substantially rigid container. In other embodiments, the pump is secured indirectly the flexible bag or substantially rigid container using, for example, a port that extends through the aperture on the bottom surface. The port or flanged surface may also be integrated into the pump, which is secured to the vessel. An optional mixing adaptor may be provided inside the interior volume of the flexible bag or substantially rigid container and at least partially covers the inlet that leads to the pump.

The invention relates to a mixer system for producing a cosmetic product. The invention also relates to a bottle for dispensing a cosmetic product. The mixer system is used to produce a cosmetic product from capsules (7, 8, 9) containing the raw materials needed in the composition of such a cosmetic product, namely the cosmetic texturiser, the cosmetic active ingredient and, optionally, a cosmetic fragrance. The invention is intended to be used in the cosmetics industry.

Blending apparatuses and related methods and computer program products are disclosed. In an aspect, blending apparatuses and related methods and computer program products of the present disclosure may include at least one energy source associated with the blending apparatuses such that at least one energy source may be used to provide at least one portion of the energy required for a given blending apparatus to function, thereby reducing or eliminating need for a separate energy source to power the blending apparatus, which reduces the overall spatial footprint required by the blending apparatus and other device(s) associated therewith. Energy generated by the at least one energy source may also be used to power one or more additional devices. Blending apparatuses of the present disclosure may additionally comprise at least one control station that allows one or more users to monitor, adjust, control, interact with the blending apparatuses, thereby increasing efficiency.

A mobile chemical mixing plant includes an inlet for receiving fluid; a fluid conduit for conveying the fluid from the inlet; a container for containing a chemical therein; a chemical pump for withdrawing the chemical from the container and directing the chemical into the fluid conduit for mixing with the fluid in the fluid conduit to form a chemical mixture; and a homogenization pump for pumping the chemical mixture in the fluid conduit out of the mobile chemical mixing plant. The fluid conduit connects the chemical pump to the homogenization pump. The mobile chemical mixing plant is fixed to a trailer that is attachable to a vehicle. Because the fluid conduit directly connects the chemical pump to the homogenization pump, the mobile chemical mixing plant does not need an intervening mixing tank for mixing the fluid and the chemical.
