A process dilutes an aerosol by feeding an input aerosol through an inlet pipe surrounded by an annular space to a first mixing stage. An output aerosol leaves purified via an outlet as a particle-free clean gas. The particle-free clean gas is fed to the annular space upstream of the outlet and is mixed with the aerosol. A mixing stage includes an inlet pipe feeding aerosol as inlet aerosol. A downstream purification device purifies outlet aerosol leaving the mixing stage via an outlet pipe to form the particle-free clean gas. A mass flow controller and a pump suction off the outlet aerosol from the outlet pipe. A return line, for the clean gas, leads upstream into the annular space.

A filter well mountable dispenser holder securable within a hot tub filter well with the dispenser holder supporting replaceable dispersant containing dispensing cartridges positionable within a circulating flow of water through the filter well to thereby release dispersants therefrom without preventing the circulating flow of water from passing through the filter media proximate the dispensing cartridges.

A system and method for the purification of beverage fluids, primarily alcohol beverages, based on the action of hydrodynamic cavitation processing of microbiological and chemical contaminants, micro particles and colloidal particles. The system is a batch system with a single vessel having an extraction tube and discharge tube extending into the same reservoir of fluid. Fluid is drawn through the extraction tube and forced through the discharge tube. The discharge tube contains cavitation elements dispersed along its length to generate hydrodynamic cavitation in the fluid as it is pumped through. The discharge fluid is mixed with the fluid already in the vessel and is re-drawn through the extraction tube in continuous batch processing.

A control unit has as agitation mode in which a command is executed for a first switching valve so that the oil supply/discharge direction is switched so as to supply oil to a first oil supply/discharge port located at a low position and discharge oil from a second oil supply/discharge port located at a high position, whereby oil in an oil bath is agitated via a circulation pump from a low position to a high position is the oil bath; and a filter mode in which, after the agitation mode is executed, a command is executed for the first switching valve so that the oil supply/discharge direction is switched so as to discharge oil from the first oil supply/discharge port located at a low position and supply oil to the second oil supply/discharge port located in a high position, whereby impurities in the oil sent to a filter mechanism are filtered.

In order to efficiently produce a liquid containing ultrafine bubbles of a desired gas, an ultrafine bubble-containing liquid producing apparatus includes a gas dissolving unit that dissolves a predetermined gas into a liquid, and a UFB generating unit that generates ultrafine bubbles in the liquid in which the predetermined gas is dissolved. A CPU performs control under a first condition in a case of causing the gas dissolving unit to operate in a circulation route passing through the dissolving unit. The CPU performs control under a second condition different from the first condition in a case of causing the UFB generating unit to operate in a circulation route passing through the UFB generating unit.

A multiple tank acid mixing and delivery system for receiving and managing a plurality of fluids and mixing a final acid mixture for use in hydraulic fracturing process. The multiple tank acid mixing and delivery system comprises a support frame, a mix tank, an acid tank, a plumbing system, a control system, and a water manifold, a main connection manifold.

The present invention provides an ultrafine bubble-containing liquid producing apparatus capable of reducing the possibility of intermitting supply of a UFB-containing liquid. An ultrafine bubble-containing liquid producing apparatus includes producing units that produce an ultrafine bubble-containing liquid containing ultrafine bubbles by using a liquid supplied from a liquid introducing unit and deliver the produced ultrafine bubble-containing liquid to a liquid delivering unit. The producing units include a plurality of ultrafine bubble generating units capable of operating independently. Each of the plurality of ultrafine bubble generating units is provided to be capable of independently switching between communicating with and being disconnected from the liquid introducing unit and the liquid delivering unit.

A tank on a firefighting aircraft initially is loaded with water. A polymer gel emulsion vessel is provided on the aircraft, but is not activated and mixed with tank water until such polymer gel preparation is initiated by an operator. When initiated, a pump pulls water from the tank and doses it with gel emulsion. Double elbows and/or the pump impeller fully activates the polymer gel. The activated polymer gel is mixed within the tank by one of a variety of systems including mixing paddles or sparging with gas. In one embodiment, a hollow tower of telescoping form has a float to keep an upper end near a surface in the tank and a sparging gas entry is a controlled distance below the surface, such that gas of limited pressure, such as from a ram air inlet can sparge and mix the water and activated polymer gel emulsion effectively.
