A tensile structure density current baffle for use in a clarifier tank having a side wall includes a tensioning cable and a central baffle portion formed from a membrane fabric. The central baffle portion has an upper baffle portion with an upper end, a lower baffle portion with a lower end, and a junction between the upper baffle portion and the lower baffle portion. The tensioning cable engages the central baffle portion at the junction. The upper end of the central baffle portion being fastenable to the side wall above the junction and the lower end of the central baffle portion being fastenable to the side wall below the junction. When the upper end and lower end are fastened to the side wall and the tensioning cable is tensioned, the tensioning cable and membrane fabric comprise a self-supporting tensile structure that extends toward the center of the clarifier tank.

A method and an apparatus for receiving manure from a vacuum truck, as that manure is collected from alleys of a dairy barn, includes receiving the manure in a mixing basin. The received manure is diluted in the mixing basin with a jet of water discharging a sufficient volume of water to form a sand-laden manure flow having a velocity of over 3 feet per second and dilute the received manure into a sand-laden manure suspension of less than seven percent manure solids. The resulting sand laden manure suspension is conducted into a vestibule of a sand settling lane to slow the flow of the sand laden manure suspension to enter a sand settling lane at a velocity of less than 1.25 feet per second. Sand is collected in the sand settling lane. Gravity urges the sand from the sand-laden manure suspension as it flows through the sand settling lane.

The “sludge dehydrator” equipment is a machine that permits to remove low turbidity water from sludge or watery pastes of industrial or mining origin, with the following objectives: To optimize ore recovery processes such as flotation by means of an increase of the sludge density; To thicken sludge or watery pastes for optimizing the filtering and drying processes, as well as to dispose of mining tailings; To concentrate and dispose of solids in suspension and to recover and recycle clean or clarified water. The “sludge dehydrator” equipment has been designed on the basis of a rectangular tank provided with the necessary infrastructure for containing inside a series of suction plates being connected to a vacuum system, through which the process of solid-liquid separation is carried out and, on the other hand, to contain the cleaning mechanism—the cleaning car—with its motor system made up by pneumatic or hydraulic components required to clean suction plates the filtering medium and to keep them permanently operative. In accordance with the “sludge dehydrator” feeding and the design of the lower or bottom cone of the rectangular tank will benefit to be derived from the industrial and mining operation.

A fluid separator unit includes an elongate body having a circular internal cross-section and a longitudinal axis, an inlet which directs a fluid flow into the body in a rotational flow pattern around the longitudinal axis, a first outlet, a second outlet, a first centrifugal separation zone arranged within the body, a second centrifugal separation zone arranged within the body, a first fluid path from a central part of the first centrifugal separation zone to the first outlet, a second fluid path from an outer periphery of the second centrifugal separation zone to the first outlet, and a third fluid path from the second centrifugal separation zone to the second outlet. A diameter of the second centrifugal separation zone is smaller than a diameter of the first centrifugal separation zone.

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.

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 separator.

A system is provided for covering a launder channel of a clarifier tank, the launder channel having a tank wall and launder channel wall. The system comprises a mounting section connected to the launder channel wall, a hinge, and an openable cover panel, movable between a closed and open position. The mounting section includes an angled resting structure for supporting the cover panel, when in the open position, away from the mounting section.

Emergency Core Cooling System under loss-of-coolant accidents, including a sump protection device (SPD) in the emergency cooling system of a VVER, and the filter module and filter element of the sump protection device, which is to protect sumps from accumulation of debris in case of a loss-of-coolant accident.

Disclosed is a VVER emergency cooling system sump protection device, comprising a system of filters installed at the intake opening of the upper part of the sump located in the reactor containment bottom and connected to the intake of emergency cooling system pipeline. It consists of header-connected filter modules preventing debris from entering the intake of emergency cooling system pipelines; each filter module has slotted grates on sides and on top, and filter elements arranged inside are designed as laterally slotted filtration pipes and perforated distribution tubes (inside the pipes) the inner cavities of which are connected to headers.
