A system for processing fluids is disclosed including a pump in fluid communication with a used fluid pit, a membrane separator in fluid communication with the used fluid pit, wherein an insert is disposed within the membrane separator, and a clean fluid pit in fluid communication with the membrane separator.

This disclosure describes methods to separate solids from liquids in a production facility. A process separates components in the process stream by applying non-condensable media to create density differences and then using a mechanical device to separate the solids from the liquids based on the density difference. The process produces the liquids and solids, which may be further processed to create valuable animal feed products.

A method for purifying biological dust suppressant by two-stage ultrafiltration is provided, which utilizes the differences of physical characteristics such as solubility and molecular morphology of each substance in fermentation broth to separate and purify the target product by two-stage ultrafiltration. Firstly, the fermentation broth is centrifugally pretreated to separate insoluble substances such as microbial cells; after centrifugation, the supernatant passes through a primary ultrafiltration membrane, and the polysaccharide, lactic acid and aggregated biological dust suppressant molecules with molecular weights more than 20 kilodaltons are cut off; organic solvents such as methanol and ethyl acetate are added to the retentate for dilution, further filtering is carried out with ultrafiltration membrane with a cutoff molecular weight more than 10 kilodaltons to obtain liquid product, and finally preparing solid purified product is conducted through rotary evaporation and constant temperature drying.

Proposed is a carbon dioxide and sulfur oxide capture and carbon resource conversion system for coal-fired power generation, the system being capable of capturing and converting carbon dioxide in an exhaust gas into a carbon resource by using a basic alkaline mixture solution, thereby being capable of reducing carbon dioxide and also capable of manufacturing sodium carbonate or sodium bicarbonate. In the system, sodium carbonate or sodium bicarbonate manufactured from the captured carbon dioxide is used as a desulfurization agent capturing sulfur oxide in an exhaust gas discharged from a coal-fired power generation plant, and carbon dioxide and sulfur oxide are simultaneously captured, so that an additional flue gas desulfurization equipment is not required to be mounted. Accordingly, the installation space of the desulfurization equipment for removing pollutants contained in gas introduced into carbon dioxide capture equipment may be minimized, and the process cost may be reduced.

For powering a vehicle, a high energy density fuel is preferred. However, for example when the high energy fuel is highly concentrated hydrogen peroxide, this fuel may be dangerous to handle; especially when the person handling the fuel is a normal consumer filling a fuel reservoir of his vehicle at a gas station. The present invention therefore provides a vehicle arranged to receive a diluted-and thus safer-fuel, and to densify this fuel to a concentrated fuel in low quantities on board for direct use. To this end a fuel densifier is provided in the vehicle arranged for receiving liquid diluted fuel and arranged to provide a concentrated fuel based on the diluted fuel, the concentrated fuel having a higher energy density than the diluted fuel. A power conversion module of the vehicle is arranged to convert the concentrated fuel to kinetic energy for powering the vehicle.

The invention relates to a method for recovery and purification of human milk oligosaccharides (HMOs) from a fermentation broth, comprising the steps of separating the fermentation broth to form a separated HMO-containing stream and a biomass waste stream, purifying the separated HMO-containing stream, concentrating the purified HMO-containing stream, and drying the purified HMO-containing stream to obtain solidified HMO. Moreover, the invention also concerns a human milk oligosaccharide obtained by the inventive method, as well as its use in food, feed, and medical application.

The present invention discloses a microencapsulation method for improving stability of anthocyanin, a product therefrom and use thereof. A preparation method of anthocyanin microcapsules includes: (1) taking sodium alginate as a wall material, adding sodium alginate and calcium carbonate into water, and swelling for 1-2 h to obtain a wall material gel system; (2) taking anthocyanin prepared by a special process as a core material, and fully and uniformly mixing the wall material gel system with an anthocyanin solution to obtain a water phase; (3) mixing Span80 and vegetable oil to obtain an oil phase, mixing the water phase with the oil phase, and magnetically stirring for emulsifying to obtain a W/O emulsion; and (4) adjusting the pH of the W/O emulsion to be acidic, mixing the W/O emulsion with a salt buffer solution, standing for 1-2 h, and then separating the oil phase and the water phase.

Per- and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water is concentrated in a reverse osmosis step and salt from the resulting solution is removed in supercritical conditions prior to destruction of PFAS in supercritical conditions.
