A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

A system and method for the separation of oil and water. Contaminated water is introduced into a settling and separating bowl through an inlet pipe. The contaminants float to the top and are recovered by a weir skimmer. The weir skimmer is fluidly connected to a recovered oil tank which receives the recovered oil. An oil separator filter belt is located in the separating bowl and separates the bowl into two segments: an upstream end on the side closest to the inlet and a downstream end on the opposite side of the inlet of the belt. The oil separator filter belt aggregates entrapped and entrained oil and other contaminants.

A method for treating wastewater in a wastewater treatment plant includes passing the wastewater passes through a rake system and, thereafter, a sand trap to separate from the wastewater, solids having different particle sizes. A screening device screens the wastewater emerging from the sand trap to yield a primary sludge that fails to pass through the screening device and a suspension passing through the screening device. The suspension is fed to at least one further treatment stage, and the primary sludge is thickened with the aid of at least one thickener. The thickened primary sludge is fed to one or several further treatment stages. Moreover, a wastewater treatment plant for treating wastewater is described.

A two-vector centrifuge rotates on a central axis, while each centrifuge drum also rotates on the drum's own axis. The inside of each drum has flighting or threads to direct and force material to the bottom of the drum as the two-vector centrifuge rotates. Perforations in the top part of the drum allow liquids to be expelled from the drum, while dried, solid material is ejected though a gap in the bottom of the drum. A pair of troughs keep the ejected liquid fraction separate from the ejected solid fraction, and each fraction is removed from the centrifuge while the centrifuge is operating, allowing the centrifuge to run for extended periods without needing to be cleaned or have accumulated material removed.

A method of filtering a main fluid using a rotary fluid filter. A 360 degree filtration cycle is initiated by receiving, at an initial position, a first portion of a main fluid at a front end of a first fluid flow passage extending through a filter body rotationally mounted within a housing. The filter body is rotated in a rotation direction and the first portion of the main fluid is discharged from a rear end of the first fluid flow passage, having passed through a filter received in the first fluid flow passage. The filter body is rotated further in the rotation direction and a first portion of a backwash fluid is received through the first fluid flow passage from the rear end to the front end. The rotational cycle is completed by rotating the filter body back to the initial position.

A dip tank and recycling system for applying antimicrobial solution to food items, including a dip tank having a bottom and sides, and holding a liquid antimicrobial solution. A conveyor to convey food items through the tank passes through the liquid antimicrobial solution held in the tank such that food items conveyed on the conveyor are dipped in the liquid antimicrobial solution. At least two discharge nozzles spray fresh antimicrobial solution into the tank. The discharge nozzles are located in the sides of the tank, and are positioned above the level of the conveyor but below an expected top level of the liquid antimicrobial solution contained within the tank such that food items conveyed on the conveyor are agitated by the force of the spray from the discharge nozzles. The spray from the discharge nozzles causes unstacking of items on the conveyor, producing an even application of the antimicrobial solution.
