The speed, effectiveness, and convenience with which pallets and other objects are cleaned can be increased by using a vehicle-towed portable pressure power-washing apparatus. The apparatus includes a platform that can be towed. On the platform is positioned at least one pressure-washer that pumps liquid from a tank into rotary arms within a cleaning chamber positioned on the platform, causing the rotation of the arms as the arms eject streams of the liquid pumped under a high pressure from angled nozzles. Belt conveyors carry an object in need of cleaning into the cleaning chamber, first exposing the object to the streams of the liquid, and then to a drying chamber. Guide rails positioned on the platform guide the object during cleaning, with the shape of one of the guide rails causing the object to fall off the platform following the drying to remove excess liquid left on the object.

A system and method are disclosed for separating solids from a slurry recovered from a hydrocarbon well. The system includes inverted pyramidal shaped compartments for settling solids downwardly within the liquid stream. Further, each compartment includes a desander pump and a desilter pump that draws solids from the partially cleaned slurry into a desander and desilter, respectively, for removal of solids from the stream. The system includes a network of Weir plates for directing cleaned slurry streams downstream through successive compartments.

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.

A brief description of the device

The machine works by frequency pressure, which is punctuated by a regular discharge of the pressure inside it and has a moving heart, a frequency movement which makes oil cleaning process not affect the basic oil properties and avoid the compression and adhesion of oil on the filters and clogged openings and oil enters the mechanism of the internal environment of the flattened and not the outer can save the deposits inside And disposal

Cleaning the surfaces of filters for the device it self because of its internal movement and there is space to collect the sediment, water disposal and cleaned manually or automatically

A process mechanically breaks colloidal suspension bonds with the surrounding fluids through high energy impact with a stationary plate or a colliding fluid stream. The fluid with a colloidal suspension is pumped through one or more to 3 nozzles to collide with either a stationary plate in an impact chamber at high velocity, another similar or different fluid stream, or both another fluid stream and an impact plate. The process breaks the bonds maintaining the colloidal suspension, disassociates these materials, and allows for gravity or chemical separation of the previously colloidal particles from the fluid. The process can separate colloidal particles from a liquid medium through pressurization followed by high energy impact and rapid release.

The present disclosure is directed toward a suction nozzle operable to remove solid contaminants from a fluid without causing a substantial increase in fluid resistance. The suction nozzle has a vertical flow path, a contaminant precipitation recess opened upward under the vertical flow path, and a lateral flow path extending laterally from the vertical flow path at a position above the contaminant precipitation recess. The fluid sucked from a suction opening in the lower surface is led to the vertical flow path through the lateral flow path and flows upward through the vertical flow path to reach a connection port. With fluid flowing through the vertical flow path, solid contaminants contained in the fluid settle down by gravity and precipitate in the contaminant precipitation recess and are separated and removed from the fluid.

A recovery system for large-scale spilled oil flowing onto and adhered to a shore is disclosed. The recovery system for large-scale oil flowing onto and adhered to a shore is mounted on an amphibious vehicle that can move on a neritic zone and land. A skimmer assembly is installed in a front of the amphibious vehicle. An oil collection assembly is foldably provided on each of front opposite sides of the amphibious vehicle, thereby easily collecting oil. A recovered oil treatment assembly is mounted on the amphibious vehicle and configured to accommodate the oil recovered by the skimmer assembly therein and to store separated oil by separating water from the accommodated oil.

Systems and methods for separating a flowback mixture received from a wellbore. Employing a vessel with internal chambers to receive the mixture and employing eductors and a shaker to manage the separation of the mixture to produce a supply of solids-free liquid ready for reuse.

An apparatus and methods for the separation of macroscopic solid body particles (SBPs) from a fluid stream contained in a conduit, such as a hose or pipe. The method involves utilizing a particle separator having a fluid inlet port connected to a fluid inlet conduit and a fluid outlet port connected to a fluid outlet conduit to change the direction (and optionally the velocity) of the fluid stream within a lumen of an enclosed vessel component of the particle separator sufficiently to permit SBPs to fall by gravity (and/or to descend due to inertia) into a removable receptacle within a bottom portion of the vessel component while directing the flow of cleansed fluid to the fluid outlet port of the particle seperator.

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.
