An apparatus that allows for separating and collecting a fraction of a sample. The apparatus, when used with a centrifuge, allows for the creation of at least three fractions in the apparatus. It also provides for a new method of extracting the buffy coat phase from a whole blood sample. A buoy system that may include a first buoy portion and a second buoy member operably interconnected may be used to form at least three fractions from a sample during a substantially single centrifugation process. Therefore, the separation of various fractions may be substantially quick and efficient.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

Techniques for recovering a hydrocarbon fluid from a waste fluid include transmitting a plurality of wave energy pulses through a waste fluid, the waste fluid including a mixture of a hydrocarbon fluid and a non-hydrocarbon fluid; receiving a plurality of reflected wave energy pulses transmitted through the waste fluid; determining a level difference between a surface of a hydrocarbon fluid layer that includes the hydrocarbon fluid and a surface of a non-hydrocarbon fluid layer that includes a non-hydrocarbon fluid based, at least in part, on the plurality of reflected wave energy pulses; and operating a hydrocarbon fluid pumping assembly, based on the determined level difference, to circulate a portion of the hydrocarbon fluid in the hydrocarbon fluid layer from the waste fluid.

A water skimmer has a float portion supporting a drain portion for draining water from a sediment basin. The drain portion includes a first pipe connect via flexible couplings to a second pipe and then to a water removal system. Water enters the first pipe's orifice through a removable, restrictive orifice saddle. The first pipe is bolted to the float portion using a guard and brackets that hold first pipe just below the water surface to receive water with less sediment. The guard also blocks floating debris while allowing water to flow to the weir under its bottom edge. As the water level rises and falls, the flexible couplings and float portion help maintain first pipe horizontal.

A weir including a suction well. The suction well may include a circular base having a suction port. The suction well further includes a cylindrical sidewall upstanding from the base. The cylindrical sidewall includes an upper edge defining an open top end. The cylindrical sidewall further includes a plurality of intake slots formed therethrough. The intake slots have an elongated shape and are vertically disposed relative to the base. A float radially extends from the sidewall. The float has a buoyancy such that the weir floats in a liquid, such as water or other coolants.

A system and method for producing high levels of autologous IL-1RA cytokine, includes a blood collection vessel, a cover, a portion of separation gel, an anticoagulant portion, a plasma collection syringe comprising a sharp needle, a buffy coat collection syringe and an incubation tube with cover. The blood collection vessel is adapted such that when containing whole blood and being centrifuged, after treatment yields separation fractions comprising, a first fraction of RBCs sediment, a second fraction of said gel, a third fraction comprising WBCs, platelets and a fourth fraction of plasma solution.

The present invention relates to a system and method for producing high levels of autologous IL-1RA cytokine, comprising: a blood collection vessel (1), a cover (4), a portion of separation gel (2), an anticoagulant portion (3), a plasma collection syringe comprising a sharp needle (9), a buffy coat collection syringe (11) and an incubation tube with cover (15). The blood collection vessel is adapted such that, when containing the whole blood (5), and centrifuged after treatment, yields separation fractions comprising, a first fraction of RBCs sediment (6), a second fraction of said gel (2), a third fraction comprising WBCs, platelets and a fourth fraction of plasma solution (8).

A skimming and separation device includes an outer casing (1) having constructions to directly or indirectly fasten all parts, including a number of inflow tubes (20), and defining a closed container (19). The device includes a floater (5) configured to create a skimming function. The floater is attached at its lower side to an essentially vertically arranged bellow (23) allowing the floater to adapt flow into a substantially circum volume that is allowing flow in a downward direction into the inflow tubes (20), which allow debris and floating pollutions to enter below the accumulated debris and floating pollutions to preferably set the internal fluid inside the casing (27) in horizontal circular rotational motion as a result of a power device (7). The power device is controlled by a control unit such that various kinds of flows and pressures may be generated to control the in-flow and out-flow of the device.
