Disclosed herein are a method for producing a miniaturized liposome on a large production scale, and an apparatus for producing a liposome which is to be used in the above-mentioned method. Provided is a method for producing a liposome, including a step of stirring a mixture containing an oil phase in which at least one lipid is dissolved in an organic solvent and a water phase in a first tank of an apparatus having the first tank and a circulation path, in which the ratio of the capacity of the circulation path to the total capacity of the tank and the circulation path is 0.4 or less and/or the time required for the mixture to return to the first tank after being discharged therefrom is within 2.0 minutes.

Method of homogenizing a liquid, in particular a colorant for paint, in a container, comprising the steps of withdrawing liquid from the container at a first flow speed (S1) and then returning the liquid to the container at a second flow speed (S2), higher than the first flow speed (S1).

The present application relates to improvements in machines for the preparation of beverage and food products, and in particular to such a machine which utilizes a compressed tablet of food or beverage product, which is inserted into the brew chamber of the machine, into which a liquid is directed to break up or dissolve the tablet. The machine for preparing a beverage or food product from a compressed disc of at least one ingredient includes a sealable brew chamber, and said brew chamber includes means for mounting the disc so that it is able to spin freely around a central axis. The brew chamber further includes an at least one nozzle having an outlet in the brew chamber located to direct a jet of liquid at a peripheral edge of the disc mounted in the brew chamber.

The device is a gas-liquid mixing device having a venturi structure in which a throat portion and an enlarged diameter portion are provided in a main passage through which a liquid passes, the gas-liquid mixing device including a collision chamber provided on an outer periphery of the enlarged diameter portion, and a stirring chamber provided downstream of the enlarged diameter portion. A collision flow path communicating with the collision chamber and causing a gas-liquid to collide with an outer peripheral wall, a straight flow path through which the gas-liquid passing through a central portion of the enlarged diameter portion travels straight, and an outer ring flow path through which the gas-liquid flows from the collision chamber to the stirring chamber are formed downstream of the enlarged diameter portion. The gas-liquids from the outer ring flow path and the straight flow path are stirred in the stirring chamber.

An all-in-one mobile wellsite service unit for providing equipment and services at an oil and gas well related to well abandonment is provided. The mobile unit comprises a water storage tank, at least one cement mixing barrel for mixing a cement slurry, a progressive cavity pump for pumping the cement slurry, and a hydraulic hose for connecting to a hydraulic power source to provide power to the cement mixing barrel and the progressive cavity pump. The mobile unit may also contain downhole tools needed for well abandonment, including a well cleaning tool, a cementing tool, a hydraulic packer, and more.

Wastewater treatment systems are disclosed. A wastewater treatment system includes a wastewater conduit disposed in a wastewater treatment vessel, a pump comprising an intake and an outlet connectable to the at least one opening of the wastewater conduit, and an adapter comprising a first end and a second end. The adapter is configured, in a treatment mode, to provide a flow path for wastewater from the wastewater treatment vessel through the adapter and pump to the wastewater conduit. The adapter is further configured to, in a backflush mode, provide a flow path for wastewater through the plurality of nozzles of the wastewater conduit and through the adapter and pump for discharge into the wastewater treatment vessel. Methods of treating wastewater using the system and adapter are disclosed. Methods of retrofitting a wastewater treatment system by providing the adapter are disclosed.

The present disclosure includes methods of making a brine solution that include recirculating brine solution to a salt and water hopper from a holding tank. The present disclosure also includes an apparatus for making a solution that includes at least one nozzle assembly positioned inside the lower half of a hopper. The at least one nozzle assembly includes a manifold having at least two nozzles spaced apart. Each nozzle has one or more nozzle outlets that are directed away from the bottom of the hopper (e.g., toward the top of the hopper).

An apparatus for stable nano emulsion of water in diesel fuel, including: a diesel fuel feeding unit (2), a water feeding unit (3), a magnetite nano-particles feeding unit (4); a mixing tank (7) in fluid communication with the diesel fuel feeding unit (2), with the water feeding unit (3) and with the magnetite nano-particles feeding unit (4); a recirculation conduit (8a, 8b, 8c, 8d) presenting opposite ends connected to the mixing tank (7). A pump (9) on the recirculation conduit (8a, 8b, 8c, 8d) and configured to recirculate a mixture of diesel fuel (F), water (W) and magnetite nano-particles (MNP). A dynamic magnetic field generator (25) is operationally coupled to the recirculation conduit (8a, 8b, 8c, 8d) and is configured to generate a dynamic magnetic field inside at least a section of the recirculation conduit (8a, 8b, 8c, 8d) to activate the magnetite nano-particles.
