A flexible tank (10, 110) for transporting fluids in a transportation container (12) is described, the flexible tank (10, 110) defining a tank (10) volume for containing a fluid. The flexible tank (10, 110) comprises at least one mixing member (146, 46) enclosing a fluid pathway (160, 60) extending across an interior surface (144, 44) of the flexible tank (10, 110), the flexible tank (10, 110) further comprising at least one inlet valve (140, 40) configured to allow the passage of fluid from outside said flexible tank (10, 110) into said fluid pathway (160, 60). The mixing member (146, 46) further comprises at least one aperture (154) such that the inlet valve (140, 40) is in fluid communication with the tank (10) volume via the fluid pathway (160, 60). An intermodal container (12) comprising the flexible tank (10, 110) and a method of mixing a fluid with the tank (10) are also disclosed.

An analysis unit formed by an analysis body housing an analysis chamber and having a sample inlet and a supply channel configured to fluidically connect the sample inlet to the analysis chamber. Dried assay reagents are arranged in the analysis chamber and are contained in an alveolar mass. For instance, the alveolar mass is a lyophilized mass formed by excipients and by assay-specific reagents.

A wastewater treatment system includes a blower providing air to an aerator and a low pressure pulsed air mixer. The invention generally relates to a wastewater treatment system and more particularly to a wastewater treatment system to eliminate biological and nutrient contaminants from wastewater.

The invention relates to a method for devatting the grape harvest and a means for devatting a grape harvest via the pressurised injection of air or other gases in a controlled manner into self-emptying wine making vats or similar, for the purpose of emptying the grape harvest once the maceration thereof has been completed, after the homogenisation of the mixture, transferring the liquid portion to another tank and the crushed grape pulp to the press, thereby obtaining a solid phase (pomace) as a waste product which can be used to produce associated products.

A method and system for treating wastewater is disclosed. In one example the method comprises activating a mixing system that imparts a motive force on wastewater in a vessel, measuring at least one property of a first portion of the wastewater at a first time, measuring the at least one property of a second portion of the wastewater at a second time subsequent to the first time, calculating a difference between the at least one property measured at the first time and the at least one property measured at the second time, performing a determination of whether the difference is within a predetermined allowable range of differences, and responsive to a result of the determination, controlling a component of the mixing system.

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.

The invention relates to an electrochemical reactor for continuous copper electrodeposition at high current densities with copper sulfate electrolytes, which comprises devices and systems of functional means that are linked and operated in line, thereby forming a triad, for standardising operational conditions in a series of operative parallel reactors. The triad, installed in each existing or new electrolytic container, comprises: a gentle electrolyte agitation system (AGSEL) with means for pulsing control of the aeration volume diffused by bubbling directed into each inter-cathodic space; a duo of systems linked in line, which comprises a system of removable anode covers (CAR) for containing, confining and coalescing the acid mist; and an acid mist recycling system (SIRENA) that captures non-coalesced electrolyte aerosols and condenses the steam, returning same to the process, while the pollutants of the gaseous fluid from the reactor are substantially diluted.
