A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to a dispersing device mounted over or adjacent to a shaker such as a linear shaker. The shaker receives and processes the output of the dispersing device and dewaters solids. The underflow of the shaker is recirculated through the tank.

There is described a tray unit for a wastewater treatment device. The tray unit has a substantially frusto-conical profile defining an axis and a central aperture. The tray unit comprises a plurality of distinct tray sections arranged around the axis. Each tray section comprises a portion of the substantially frusto-conical profile of the tray unit and is connectable to one or more of the other tray sections so as to form the tray unit. There is also described a method of assembling a tray assembly for a wastewater treatment device. The method comprises the steps of: providing a plurality of tray units, the tray units each having a substantially frusto-conical profile and a central aperture and comprising a plurality of connecting lugs each defining a hole; attaching a first one of the tray units to a plurality of support members by inserting the support members through the hole of the connecting lug of the first tray unit and securing the first tray unit to the support member; and attaching a second one of the tray units to the plurality of support members by inserting the support members through the hole of the connecting lug of the second tray unit and securing the second tray unit to the support member to form an assembly of tray units.

A system for isolating a target molecule from a bioprocess fluid includes a single-use disposable separation device having a plurality of perimeter-bonded layers defining one or more mesofluidic channels of the separation device, wherein each layer includes a biocompatible polymer material, wherein the separation device is configured to separate at least a portion of particles from the bioprocess fluid to generate a substantially clarified bioprocess fluid, and a chromatography system fluidically coupled at the outflow of the separation device in a configuration for further processing the clarified bioprocess fluid.

A separation apparatus for separating constituents from effluent. The separation apparatus includes a gas diffuser, a hopper, and a tank. The gas diffuser includes an inlet inner tube for receiving effluent from a well. The hopper is disposed at least partially below the gas diffuser, and the tank is connected to the hopper. The gas diffuser is configured so that gas in the effluent is released from the effluent and into the atmosphere before the effluent enters the hopper. The hopper is configured so that liquid effluent in the hopper spills over a top portion of the hopper and into the tank.
