Provided is A PRP extraction kit comprises: a body that has an upper accommodation space, a lower accommodation space that is located below the upper accommodation space, and a communication passage which communicates the upper accommodation space and the lower accommodation space and of which a fluid passage area becomes narrower as it goes upward or downward, in the interior thereof; a valve unit that is located in the communication passage and allows flow of the communication passage to go only in one direction while being moved by a self-weight based on a change in a vertical position of the body; and a variation means that is coupled to a lower side of the body and vertically moves based on manipulation of a user to vary the volume of the lower accommodation space.

A separation apparatus that includes a weir tank having a plurality of cells and fluid removal apparatus for each cell to remove the fluid from each cell. The fluid removal apparatus includes an actuator and an extension arm whose movement is caused by the actuator. In addition to the actuator and the extension arm, the fluid removal apparatus includes a plunger attached to the extension arm for selectively engaging a first opening in each cell. Furthermore, a method of removing fluid from the separation apparatus via the fluid removal apparatus.

A system for separating a heavy fraction from a liquid includes an upper section in fluid connection with-an inlet, an impeller within the upper section and a flow restrictor positioned below the impeller having a diameter less than the diameter of a a lower section housing to form a gap between the flow restrictor and the lower section housing. An inlet of a conduit is positioned radially inward from an interior wall of the lower section housing and below the flow restrictor. The conduit includes an outlet outside of the lower section. The lower section is generally cylindrical from the top of the gap to a baffle positioned below the flow restrictor, which defines a settling section. The lower section further includes a slurry outlet in operative communication with the settling section.

A grit removal unit including an influent channel directing wastewater with grit into a round grit removal chamber and an effluent channel receives wastewater output from the chamber. A divider wall extends upwardly between the sides of the influent channel, and gates at the upstream end of the divider wall are adjustable to selectively open channel portions on opposite sides of the divider wall. An output guide member is mounted to allow selective adjustment of output flow opening width c to the effluent channel. The output guide member has a horizontal bottom extending from the chamber into the effluent channel across the width of the output opening, and a guide wall extending upwardly from the guide member bottom. The guide wall has a forward end spaced from the chamber annular vertical wall to define the output flow opening width therebetween.

This invention describes the equipment and a method to recover starch from a dilute starch stream produced by manufacturing facilities which process the starch-containing materials, such as potato and corn. The process comprises feeding a dilute aqueous slurry of less than about 5% by weight starch to a classifier to concentrate the slurry by a factor of at least 5 and produce a concentrated slurry, wherein the classifier has at least one overflow exit and at least one underflow exit; drawing off the overflow and underflow from the classifier; feeding the concentrated slurry from the underflow exit of the classifier into a settling tank having at least one underflow exit and at least one overflow exit to produce an underflow layer of starch with a concentration of at least 40% starch proximate to the underflow exit and an aqueous overflow with a concentration of less than about 5% by weight starch proximate to the overflow exit; drawing off the overflow from the tank; and opening a orifice at the underflow exit of the tank to allow the distal most fraction of the underflow to exit the tank.

A tank system may be conventional and fixed, or mobile, such as a fracking fluid or other tank trailer. A drain port thereof is fitted with an adapter connecting a snorkel system to drain liquids from near the top of the liquid level in the tank. A snorkel head at the extreme distal end of a tube near the longitudinal center of the tank is suspended by a system of buoys. A flow field controller plate resists formation of vortices near the snorkel head, so it can operate as near the surface as possible, withdrawing the highest grade oil efficiently. At its exit, the proximal end of the tube drains oil through an inner conduit of an adapter at a penetration in the wall of the tank. The adapter forms an annulus around the inner conduit draining tank bottoms directly from the tank.

Disclosed herein is a method for recovering an acid or a base during a metal extraction process. The method comprises contacting a feed stream comprising the acid or base and the metal with an ultrafiltration membrane to produce an ultrafiltration retentate and an ultrafiltration permeate, and contacting the ultrafiltration permeate with a nanofiltration membrane. The nanofiltration retentate produced comprises a majority of the metal from the feed stream, and the nanofiltration permeate produced comprises a majority of the acid or base from the feed stream. Also disclosed herein is a recovery apparatus for recovering an acid or a base during a metal extraction process.

A system for removing particulate matter from a multiphase stream comprising gas, liquid and the particulate matter. The system comprises a first vessel for receiving the multiphase stream and separating a majority of gas from the multiphase stream and collecting a slurry of liquid and particulate matter; a second vessel for receiving the slurry and causing separation of the particulate matter from the liquid and for generating a pressure head of liquid against the particulate matter; a third vessel for receiving the particulate matter from the second vessel and collecting the particulate matter until a pre-determined mass or volume of particulate matter is collected; and an outlet in the third vessel for conveying the particulate matter out of the third vessel.
