Various implementations include an aeration device. The aeration device includes a venturi tube and an outlet tube. The venturi tube has an outlet port and an air intake port. The outlet tube has a first end coupled to the outlet port of the venturi tube, a second end opposite and spaced apart from the first end, and an intermediate portion disposed between the first and second ends of the outlet tube. The intermediate portion is helically shaped and extends around a helical axis of the intermediate portion. The intermediate portion extends at least one rotation about the helical axis.

In a method for infusing a gas from a gas source into a liquid beverage, liquid beverage is driven from a beverage container into a liquid inlet port of a venturi mixing device. Nitrogen is infused into the liquid beverage by driving nitrogen through a gas inlet port of the venturi mixing device, thereby delivering nitrogen-infused liquid beverage to a discharge port of the venturi mixing device. The nitrogen-infused liquid beverage is poured from the discharge port through a faucet.

A chemical component mixing apparatus for use with a fluid source in creation of a concentrated solution mixture is described. The mixing apparatus includes at least one mixing station. The mixing station includes an injector assembly, where the injector assembly includes at least one venturi chamber having at least one suction port in fluid communication with the at least one venturi chamber. The apparatus also includes at least one super concentrate chemical component housed within a chemical container, where the chemical container is fluidly connected by a first tube to the at least one venturi chamber via the at least one suction port, a receiving container fluidly connected to the injector assembly via a second tube, and a fluid source inlet introducing a fluid into the at least one mixing station, where the pressure within the at least one mixing station is less than 150 psi. The fluid passes through the at least one venturi chamber, thereby drawing the at least one super concentrate chemical component into the venturi chamber, and the concentrated solution mixture is dispensed from the injector assembly into the receiving container.

An aerator for aerating a liquid as the liquid is being poured from a container includes an aerator body configured to be at least partially inserted into the container. The body includes an inlet, an outlet, and a flow control chamber disposed between the inlet and the outlet. A flow control element is movably disposed in the flow control chamber between a first position where the flow control element is spaced away from a stop and a second position where the flow control element engages the stop. The flow control chamber communicates with the outlet when the flow control element is in the second position allowing liquid to be poured from the container and allowing air to be introduced into the flow control chamber for mixing with the liquid being poured from the container to aerate the liquid being poured from the container.

A micro-bubble generator has an intake manifold, a casing threadingly connected to the intake manifold, a first air inlet channel defined between threads of the intake manifold and the casing, a booster located inside the casing and having a gap defined between the casing and the booster to form a second air inlet channel and to communicate with the first air inlet channel, a bubble generating tube located inside the casing and having a third air inlet channel defined between the end faces of the bubble generating tube and of the booster. The booster includes a first water inlet and a first water outlet having an inner diameter smaller than that of the first water inlet so that water velocity at the first water outlet is faster than that at the first water inlet, which forces ambient air to enter the bubble generating tube via air inlet channels and to be mixed with water in the bubble generating tube to generate bubbles. Bubbles are cut into micro-bubbles after passing through the cutter and exit the bubble exit.

An improved system for providing a homogeneous polymer-sludge composition to dewatering equipment includes an input mechanism that is adapted to receive sludge from a first supply source, and polymer materials from a second supply source. The input mechanism functioning to perform an initial blending of the materials before discharging the same to a pump unit. The pump unit comprising a boundary layer viscous drag pump that functions to efficiently and simultaneously mix and pump the polymer/sludge material to dewatering equipment in a manner that does not shear the polymer or reduce the efficiency, as previously experienced with downstream mixing units.
