A dewatering system for separating a slurry into solid material and effluent water. The dewatering system comprises a plurality of support frames arranged to enclose an interior space of the dewatering system, with the interior space being configured to receive the slurry. The dewatering system further includes geo-fabric material positioned on a portion of the support frames, with the geo-fabric material being configured to filter the slurry received within the interior space, such that effluent water permeates through the geo-fabric material and is discharged from the interior space. The dewatering system further comprises a dump door assembly associated with at least one of the support frames, with the dump door assembly including a plurality of hatches configured to selectively open to allow effluent water to be discharged from the interior space of the dewatering system.

A modularized system for conditioning liquid fuel is provided that includes a mobile trailer and a liquid fuel conditioning skid disposed on and secured to the mobile trailer. The modularized system includes a pre-filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a pre-filter configured to remove impurities from a processed liquid fuel prior to providing the processed liquid fuel to a last chance filter. The modularized system includes a last chance filter sub-skid disposed on and secured to the liquid fuel conditioning skid that includes a last chance filter configured to remove impurities from the processed liquid fuel prior to providing the processed liquid fuel to a gas turbine engine. The pre-filter sub-skid and the last chance filter sub-skid are coupled together via piping enabling flow the processed liquid fuel between the pre-filter sub-skid and the last chance filter-sub-skid.

Embodiments of the present disclosure are directed to a device and method for the filtration of gray water from a household. In some embodiments, the gray water can be filtered using a conical rotor and filtration media, which can provide enhanced filtration through the use of Taylor vorticity filtration. The filtered water can have various uses back in the household after filtration.

Systems, devices, and methods for providing nutrient removals in an up flow filtration storm water system for treating water to very high clean levels using filtration media. A filtration media can be supported by a screen above a floor in a vault allows for incoming storm water to pass into a void space above the floor into the screen and filtration media and then out an outlet to the vault. The filtration media can include recyclable and/or natural particles. Layers of river rocks can be placed on top of and below the filtration media. The captured debris can drop to the floor. The long lasting filtration media can be cleaned by being backwashed.

An F.O.G. separation apparatus includes a tank for receiving a liquid effluent flow containing water, F.O.G., and gross solids. The tank has a chamber, an inlet in an inlet module, a downstream section and an outlet in an outlet module. The inlet module has a weir for the effluent downstream of a strainer to strain gross solids from the effluent. A pump upstream of the strainer pumps water and solids that do not pass through the strainer. The pump's rotatable vertical shaft has a motor at an upper and an impeller at the bottom. A pipe connected to the inlet module near the impeller conveys solids and water when the pump is activated and directs the solids and water to the outlet. F.O.G. and water entering the tank pass to the downstream section where the F.O.G. is removed from the water by a skimmer, and the residual water exist the tank through the outlet module.

Disclosed herein are systems, devices and methods for processing tissue, such as autologous tissue. Implementations of a Stromal Vascular Fraction (SVF) system are described that can isolate and wash harvested cells contained within various tissues, such as isolate and wash stem cells from fat tissue. The SVF system can minimize the handling and transferring of tissue and fluids, including minimizing the number of human interventions and manipulations required throughout processing. The SVF system can ensure sterility of processed tissue and harvested cells, as well as significantly reduce cost and time associated with the processing.

A particulate separating mechanism for an appliance includes a fluid inlet that receives an inlet fluid. The inlet fluid includes particulate matter. A labyrinth separator is positioned to generate a first turbulence of the fluid. The first turbulence separates a first portion of the particulate matter into a particulate collection portion. A main filter is positioned downstream of the labyrinth separator and has a constricting portion and opposing turbulence chambers that are vertically oriented to produce a second turbulence of the fluid. The second turbulence separates a second portion of the particulate matter from the fluid. A fluid outlet delivers the fluid having the first and second portions of the particulate matter removed into a processing chamber for processing articles.

A screen decanter for decanting liquid from a reservoir, comprising at least one rack comprising screens and baffles forming the sides of a cavity; a frame attached to the screens and baffles and providing a barrier so that liquid cannot pass from outside into the cavity without passing through the screens; a patterned perforated drain pipe inside the cavity and leading to an opening through which liquids may drain out from the cavity. The pattern of the openings counteracts the hydrostatic head within the rack such that flow through the screens is uniform at all depths of immersion in the liquid reservoir. Preferably, the screens have a porosity of about 50 micrometers.

A stormwater treatment device includes a tank defining an internal volume and having an inlet and an outlet, a rotatable screen unit mounted within the tank, the rotatable screen unit being barrel-shaped to define a through path with an inlet end and an outlet end. The rotatable screen unit includes a screen structure with a plurality of screening openings for allowing passage of at least some water from the through path outwardly through the screen structure while inhibiting passage of trash items through the screen structure such that trash items move along the through path from the inlet end to the outlet end. The rotatable screen unit includes a plurality of external drive paddles that rotate with the screen structure and that interact with water that has been screened by passing outwardly through the screen structure interacts with the external drive paddles to cause rotation of the rotatable screen unit.

A dirt separator including a vessel having a separation container having a lateral container wall, a container bottom, and a container axis, which container has an inlet and an outlet as well as an interior, and having a particle separation chamber, which is disposed at the outlet of the separation container and stands in a fluid connection with the separation container, an inlet for supply of liquid into the vessel, and an outlet for discharge of the liquid out of the vessel. The dirt separator is configured in such a manner that liquid introduced into the separation container flows downward along the container wall in a cyclone-like movement, and then flows upward to the particle separation chamber within the liquid that flows downward in cyclone-like manner, and the dirt separator includes at least one particle separator, which is disposed in the particle separation chamber.
