A system and a method for producing fracturing fluid, comprising: receiving source fluid from one or more inlet manifolds of a single transport, driving a first pump mounted on the single transport to route the source fluid from the inlet manifolds into a hydration tank mounted on the single transport, driving a second pump mounted on the single transport to route hydrated fluid produced by the hydration tank to a blending tub mounted on the single transport, and discharging fracturing fluid produced by the blending tub to one or more outlet manifolds of the single transport.

A fine-bubble mixed liquid producing apparatus 1 includes a reservoir 4 and a bubble feeding means 6 for feeding bubbles to a liquid L stored in the reservoir 4, wherein the bubble feeding means 6 includes a rotary cylinder 20 having an emitting part 22 on the outer circumferential surface, the emitting part 22 for being rotationally driven by a drive means 10, a circulating means 40 for drawing out the liquid L stored in the reservoir 4 and feeding the liquid L from the emitting part 22 to the reservoir 4, and a gas-liquid mixing part 50 for mixing bubbles with the liquid L circulated by the circulating means 40. This apparatus enables a fine-bubble mixed liquid to be efficiently produced.

A fluid dispersing device includes a tubular first wall portion with an axis extending in a first direction defined as a central axis, and a second wall portion separated downward from the first wall portion. The second wall portion includes at least one circular member and a disk-like member each having a flat surface for causing a fluid passing through an inner space of the first wall portion to collide therewith. The disk-like member is separated downward from the at least one circular member. The at least one circular member has an outer diameter equal to or smaller than an inner diameter of the first wall portion. The disk-like member has an outer diameter equal to or smaller than an outer diameter of the closest circular member.

A device and method for counter collision treatment. The device includes: first and second nozzle means oppositely disposed so as to inject jets of a highly pressurized fluid into a body protective ring; the injection directions of the first and second nozzle means are determined so as to intersect with an angle at one point located in front of the nozzle orifices thereof. Further, the jets from the first and second nozzle means are caused to collide with each other to thereby effect homogenization of the fluid by impact-fragmentation. Yet further, one of the first and second nozzle means is provided with a turning mechanism for enabling the nozzle to turn around the fixed injection direction as the axis of the turn while keeping the injection direction unchanged.

A module for continuously generating high-level carbonated water according to an embodiment relates to a module for continuously generating high-level carbonated water for continuously dispensing high-level water in a direct water type. The module includes: a mixing container part in which water W and carbon dioxide are mixed to generate the carbonated water; a micro water jet unit that generates a plunging jet in a direction of gravity with respect to a surface of water filled in the mixing container part; a carbonic acid gas supply unit that injects carbon dioxide gas from a lower side of the mixing container part to form a high-pressure carbonic acid gas layer in an opposite direction of gravity by buoyancy; and a carbonated water outlet unit that increases a dispersion of carbonic acid gas bubbles due to a turbulent flow formed by the micro water jet unit and the carbonic acid gas supply unit in the mixing container part to dispense the carbonated water to a lower portion of the mixing container part while the carbonated water dissolved instantaneously keeps a carbonation pressure of 3.5 or more, in which the micro water jet unit or the carbonic acid gas supply unit includes a member for an inner diameter shaft pipe for reducing an inner diameter of a first pipe part so that a microinjection port is formed in the first pipe part.
