The present invention discloses a preparation process of food-grade potassium dihydrogen phosphate, wherein phosphoric acid prepared from wet-process phosphoric acid is used for the preparation of high-purity potassium dihydrogen phosphate. The preparation process of food-grade potassium dihydrogen phosphate provided in the present invention effectively reduces the preparation cost of the high-purity potassium dihydrogen phosphate and has the advantage of high process controllability, and by such a process, high-purity potassium dihydrogen phosphate crystals that meet the food-grade requirements can be produced, which crystals have uniform particle size distribution and comprises few fine powder, having a very high market value.

Various systems, methods, and devices are provided for focusing particles suspended within a moving fluid into one or more localized stream lines. The system can include a substrate and at least one channel provided on the substrate having an inlet and an outlet. The system can further include a fluid moving along the channel in a laminar flow having suspended particles and a pumping element driving the laminar flow of the fluid. The fluid, the channel, and the pumping element can be configured to cause inertial forces to act on the particles and to focus the particles into one or more stream lines.

The invention relates to a device consisting of a reactor facility for the flow dynamics treatment of fluid or gaseous media or mixtures of the two. In the context of this invention, flow dynamics treatment means the energy-optimised production of at least one rotating fluid eddy together with an eversion of the at least one fluid eddy and the bursting open of organic constituents dissolved in the fluid medium with inner cell pressure (Turgor). The guided fluid eddy is treated, cleaned and disinfected in the reactor facility according to the invention. The invention further relates to a method for the flow dynamics treatment of fluid media in the reactor facility according to the invention.

A bio emulsion fuel manufacturing apparatus and method using vegetable oil is provided, including an oil tank unit configured to refine a vegetable oil introduced from an oil inlet by using a coagulant agent and a centrifugal decanter; a water tank unit configured to pretreat a water introduced from a water inlet by using a water tank catalyst; a first HHO gas infuser unit configured to introduce nano-bubbles into the water inside the water tank; a mixed oil unit connected to the oil tank unit and the water tank unit, and configured to produce a mixed oil by using an inline mixer; an ionization catalyst unit connected to the mixed oil unit and configured to convert the mixed oil to a bio emulsion fuel by using an ionization catalyst group; and a second HHO gas infuser unit configured to introduce HHO gas into the bio emulsion fuel.

A system for collecting and separating biological material includes a centrifuge tube, a separation tube having an open bottom, a cap, a plug for temporarily sealing the open bottom of the separation tube, and a separation medium disposable within the centrifuge tube. The centrifuge tube and the separation tube sealingly and releasably couple to the cap, such that, when coupled, the separation tube is positioned within the centrifuge tube. The cap is configured to facilitate and/or regulate the introduction of air, gas, or other matter into the separation tube. When fully sealed, the separation tube may be placed under a vacuum condition, whereby a needle apparatus is used to facilitate introduction of matter into the separation tube. When the separation tube is positioned within the centrifuge tube, the bottom portion of the separation tube is submersed in the separation medium.

Disclosed herein are systems and methods from processing flue gas desulfurization (FGD) gypsum feedstock and ash feedstocks, either separately or together. FGD gypsum conversion comprises reacting FGD gypsum (calcium sulfate) feedstock or phosphogypsum, in either batch or continuous mode, with ammonium carbonate reagent to produce commercial products comprising ammonium sulfate and calcium carbonate. A process to separate the impurities and convert the calcium carbonate to a pure precipitated calcium carbonate is disclosed. These impurities include a concentrate of valuable Rare Earth Elements, and radioactive thorium and uranium. A process to convert calcium sulfite to calcium sulfate using oxygen and a catalyst is also disclosed. Ash conversion comprises a leach process followed by a sequential precipitation process to selectively precipitate products at predetermined pHs resulting in metal hydroxides which may be converted to oxides or carbonates. The processes may be controlled by use of one or more processors.

Methods and systems for production of lithium hydroxide and lithium carbonate are described. One or more embodiments of the method include producing lithium hydroxide from potassium chloride, lithium chloride, and water. One or more embodiments of the method include producing lithium carbonate from potassium chloride, lithium chloride, water, and a carbon dioxide source. One or more embodiments of the method include producing lithium carbonate from sodium chloride, lithium chloride, water, and a carbon dioxide source.

The present invention provides a method for capturing specific cells (e.g. many types of cancer cells, including cancer cells not expressing EpCAM), and a method for analysis of specific cells involving the method. Included is a method for capturing specific cells present in blood or biological fluid, the method including: agglutinating blood cells in sampled blood or biological fluid; centrifuging the resulting blood or biological fluid; and then capturing specific cells therefrom onto a hydrophilic polymer layer.
