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 resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently without entrainment of overlying gases and vapors, nor the second liquid layered therebelow. All are configured to fit into the tank without requiring any personnel to enter the tank. Oil, water, and sludge may drain through the system to exit the tank.

A blow case with an inlet pipe positioned to gravity direct debris to an outlet pipe. The inlet pipe having a discharge end sealed by gravity open clapper style check valve that is closed by activation of pneumatic pressure through a float style pneumatic valve. The check valve has a top mounted access port and aperture allowing for direct above ground servicing access to both the clapper inside the valve and has a removable clapper and access port for servicing the outlet pipe. The float style pneumatic valve is also top mounted for ease of service and removal and is remotely positioned from the outlet pipe to allow for removal of the valve for flushing of the debris from the blow case.

Disclosed herein is a method of controlling the water flow in a water filtration system in which the filtering system may be connected to a variety of possible outside sources and pre-filtering systems, in order to ensure a continuous flow of water, eliminating the need of continual user surveillance. A combination of float valves and seals regulate water levels and prevent leakage and overflow. Ambient pressure is maintained by venting a lower chamber. Additional chamber(s) may be integrated to expand the capacity of the system.

Vaults, boxes, systems, and methods of treatment systems to capture pollutants from storm water runoff and prevent the conveyance of these pollutants from entering a receiving water body or landscape area, which is designed to be a part of a local permanent storm water drainage infrastructure. A single treatment box, vault and system combines both drainage conveyance, multi-level treatment techniques, variable hydraulic capabilities, and easy and inexpensive methods for servicing the system, along with a hinged skimmer system with or without a float. The hinged skimmer system can include a rigid vertical panel attached by pivotal support rods that allow the vertical panel to move up and down along a vertical plane in front of an outlet flow line to a vault. The system can also include components selected from a shelf or baffle beneath the hinged skimmer, a dual screened filtration system, media filtration, and hydroslide water pressure lines with spray heads for cleaning debris on a sloped floor, as well as a flow spreader, debris ramp and screened deflector.

A floating liquid intake for a liquid suction removal system, the liquid intake comprising housing defining an internal cavity. The housing has a hollow and buoyant annular body, an upper cover and a lower cover. The internal cavity is formed between the upper and lower covers. A substantially annular inlet is formed in the annular body for ingress of liquid into the cavity. The annular body has a buoyancy sufficient for the liquid intake to float in a liquid with the annular inlet submerged below the surface of the liquid in which the liquid intake is floating. A pipe extends into the cavity and the pipe includes an inlet that in use is open below the surface of the liquid within the cavity. The pipe extends outside of the cavity for connection to a liquid suction removal system.

The present disclosure relates to settler plates for a plate settler. The settler plates generally include a hollow support with a hollow interior to receive clarified liquid from a flow channel between adjacent settler plates. An orifice is formed through the hollow support to direct clarified liquid from the flow channel into the hollow interior. The orifice can be positioned such that clarified liquid can flow upwardly out of the flow channel and downwardly through the orifice into the hollow interior. The hollow support can be integrally formed with the settler plate. For example, the hollow support can be formed by bending a tab extending from an end of the settler plate. The tab can be bent into a hollow support with a cross section that is generally polygonal.

A system for obtaining plasma enriched in platelets is disclosed which is closed to the atmosphere. The system includes: a collection tube containing an anticoagulant portion and a separation gel; a first collection syringe adapted to collect a portion of fluid relatively depleted in platelets from said collection tube after centrifugation; and a second collection syringe adapted to collect plasma enriched in platelets from said collection tube after centrifugation, said second collection syringe further comprising a filter unit adapted to filter cells included in said plasma enriched in platelets.

A separator for separating a first from a second phase of a liquid in a tubular container includes a float made of elastic material having a circumferential sealing edge and at least one ballast fastened to the underside of the float. The density of the ballast is greater than the density of the float and the density of the entire separator lies in a value range between the density of the first phase and the density of the second phase of the liquid. In order to ensure an unrestricted light inflow of the liquid into volume regions of the container lying below the separator in the initial position, the float is designed disk-shaped; and that the ballast is designed in the form of a plurality of fingers extending away from the underside of the disk-shaped float, distributed at its edge.

A method and apparatus for the removal of surface scum by using an apparatus in connection with a liquid tank, including a collecting arrangement for gathering surface scum and removing the same from the liquid tank with a surface scum discharge arrangement, and an overflow arrangement based on continuous flow for separating liquid to be treated from surface scum and for removing purified liquid from the liquid tank. The presently treated liquid is overflowed from the liquid tank into a escort water collecting space included therein by way of which it is removed from the immediate vicinity of the liquid tank. The surface scum is removed with a separating arrangement by which the surface scum is first of all separated from liquid to be treated in the liquid tank below its supernatant layer of surface scum while being flowed into the escort water collecting space and is conveyed at the same time into a collecting space of the collecting arrangement.

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.
