The present invention is related to an installation and to a method for recirculating and mixing a fluid which is preferably a shear-thinning fluid. The installation comprises a tank, a pump, a piping assembly connected to the pump and comprising an injection piping for injecting said fluid into the tank and a return piping coupled to the injection piping for pumping the said fluid from the tank to the injection piping, wherein the piping assembly and the tank form a flow recirculation path in which fluid is homogenized by recirculation of the fluid upon action of the said pump, the injection piping being designed such as to reinject the fluid in at least two peripheral bottom locations with an horizontal and/or inclined orientation such as to create a swirl movement in the tank and to reinject simultaneously said fluid upwardly through a central location in a zone comprised between the central axis of the tank and the half radius of the tank such as to create a jet of fluid having a main vertical component.

A device for generating a scented mist of an atomized liquid fragrance oil includes an atomizer complex, a reservoir assembly, a drainage tube, and a vacuum tube. The atomizer complex can atomize the liquid fragrance oil into a scented mist and deliver the scented mist to air outside of the atomizer complex, where the liquid fragrance oil the fragrance oil that is not atomized into the scented mist delivered to the air outside of the atomizer complex includes collected oil that is collected and drained to a reservoir assembly. A drainage tube extends from a bottom area of the atomizer complex into the liquid fragrance oil. The device can filter the liquid fragrance oil in the reservoir assembly and the collected oil from the atomizer complex that drained down the drainage tube. The vacuum tube can suction the filtered liquid fragrance oil and the collected oil into the atomizer complex for atomization.

A water treatment system is disclosed having electrolytic cell for liberating hydrogen from a base solution. The base solution may be a solution of brine for generating sodium hypochlorite, or potable water to be oxidized. The cell has first and second opposing electrode end plates held apart from each other by a pair of supports such that the supports enclose opposing sides of the end plates to form a cell chamber. One or more inner electrode plates are spaced apart from each other in the cell chamber in between the first and second electrode plates. The supports are configured to electrically isolate the first and second electrode plates and the inner electrode plates from each other. The first and second electrode plates are configured to receive opposite polarity charges that passively charge the inner electrode plates via conduction from the base solution to form a chemical reaction in the base solution as the base solution passes through the cell chamber.

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 flotation cell for treating particles suspended in slurry and for separating the slurry into an underflow and an overflow is disclosed. The flotation cell includes a flotation tank including a center, a perimeter, a bottom, and a side wall; and a launder and a launder lip surrounding the perimeter of the flotation tank. The flotation tank further includes blast tubes for introducing slurry infeed into the flotation tank. A flotation line, as well as a use of the flotation line is also disclosed.
