Abstract: A vertically oriented vessel has a swirl plate spiraling around its inner wall surface. A nozzle injects unclean liquid onto the lower surface of the swirl plate for deflection of liquid down towards the bottom of the vessel to generate a liquid vortex flowing causing particulates to precipitate. Above the swirl plate, a preferably cylindrical filter element that filters out particulates is cleaned periodically The filter rotates on a shaft so a high pressure sprays of clean process liquid from an array of nozzles juxtaposed with the filter cleans the filter surface as particulates are flushed from the vessel.

Abstract: The present invention relates to a blood separation container for extracting self-platelet. According to the present invention, since a second coupling portion is formed at a release prevention member coupled to a lower portion of a main body in a PRP separation container, and an ascending member having a bolt structure is screwed to the second coupling portion to ascend a lower cover disposed in a lower fluid chamber of the main body, a separate second main body is unnecessary unlike the related art. Therefore, the PRP separation container is easy to carry, manufacturing costs can be reduced to thereby ensure competitive price, and a PRP can be easily separated and extracted.

Abstract: A sweeper assembly can include a plurality of holes drilled in one or more sweeper headers that can be angled downwards towards the basin floor to produce a gentle flow of fluid to keep particulate matter rolling along the basin floor. A centrifugal separator can include a curved velocity plate for smoothly directing flow from an inlet pipe to an inner wall of the separator and creating a downward vortex of particulate-laden fluid within the centrifugal separator. The centrifugal separator can include one or more reversal mechanisms for transferring particulate matter to a collection chamber and reversing the direction of particle-free fluid, which may upwardly exit through a discharge pipe. The centrifugal separator can include a bleed valve in the discharge pipe for automatically bleeding accumulated air in the “dead zone” between the inlet pipe and the top of the centrifugal separator.

Abstract: A high capacity magnetic filter separates diamagnetic and/or paramagnetic substances from fluid streams. Diamagnetic solid substances are magnetized under an external magnetic field through coordinated interaction of diamagnetic solid substances with an inducement paramagnetic material (IPM). The magnetic filter serves as a separation zone created by the presence of IPM and magnets that are shielded from the IPM by non-magnetic sleeves or partitions. The IPM in the void volume between the magnets affords large surface area onto which diamagnetic and paramagnetic materials can contact and be attracted to. The relative position and distance of the magnetic source, such a magnetic bar or electromagnet, to the solid mixture of diamagnetic and IPM are adjusted to induce sufficiently strong magnetism in the diamagnetic solids which causes the diamagnetic solids to be attracted by the magnetic field as well. Both diamagnetic and paramagnetic substances can be removed from a liquid or gas.

Abstract: An array of hollow fiber membranes is grouped into bundles is submerged in an enclosed pure-water bath. The bundles are potted into top and bottom membrane headers such that the fiber lumen (the inside of the hollow fiber) is open to the inside of the membrane header and the pure feedwater is prevented from leaking into either the header or into the inside of a hollow fiber. Pure water penetrates the hollow fiber membrane. In accordance with pressure retarded osmosis (PRO) principles, the permeate and draw solution within the lumen are transported to at least one hydroturbine where electricity is generated. The draw solution contains superparamagnetic nanoparticles that are prevented from proceeding beyond a magnetic field. The system has a heater to improve its efficiency.
