A fluid handling apparatus for ejecting fluid into a tank and draining fluid from the tank comprises: a fluid duct for draining/supplying fluid from/to the tank, the fluid duct configured for fluid communication with a tank opening at a tank bottom; a fluid inlet pipe for supplying fluid to the tank, the fluid inlet pipe extending at least partly through the fluid duct and configured to extend through the tank opening into the tank; a rotary fluid ejection device in fluid communication with the fluid inlet pipe; and a rotary drive shaft extending at least partly inside the fluid inlet pipe, the rotary drive shaft being rotatably connected to the rotary fluid ejection device. Also disclosed is a fluid tank system comprising a tank and a fluid handling apparatus, and a method for mixing beer or wort with solid hops material in a tank by a fluid handling apparatus.

Liquid effluent treatment module comprising at least one tank portion suitable for receiving a plurality of packing elements that may receive a biological material, the tank portion defining a horizontal longitudinal axis and comprising at least one effluent feed, characterized in that the tank portion further comprises: .sup.∘at least one line for collecting treated effluent arranged in a central part of the tank portion and parallel to the horizontal longitudinal axis, .sup.∘at least one air injection line arranged in a lower part of the tank portion, off-centered and parallel to the line for collecting treated effluent so as to give rise to a spiral movement of the liquid effluents.

An asphalt shingle coating system that includes a coater, a mixer, a viscosity gauge, a wax supply, a wax pump and a control system. The coater applies a layer of a coating asphalt mixture on an asphalt shingle substrate. The mixer mixes the coating asphalt mixture and is positioned upstream of the coater. The viscosity gauge may be positioned between the coater and the mixer, and it measures the viscosity of said coating asphalt mixture before it is delivered to the coater. The wax supply is in fluid communication with the mixer and a wax pump may deliver a volume of wax from the wax supply to the mixer, and the control system may selectively adjust the operation of the wax pump to substantially maintain a desired viscosity of said coating asphalt mixture.

Apparatus that mixes non-homogenous fluid. A threaded shaft within a housing circulates fluid within a container to effect mixing. In one embodiment, when placed in a container of fluid, the housing the fluid is recirculated through opposing ends of the housing. In an embodiment of a related method for mixing, a pump housing containing a screw journaled for rotation receives fluid within a container and conveys the fluid therethrough to circulate a fluid portion in the container along an exterior surface of the housing for mixing with another fluid portion to improve fluid homogeneity. After mixing, the portion of the fluid which first circulates through the housing may recirculate through the housing with said another portion of the fluid. The fluid may be continuously mixed and recirculated through the housing.

The gas dissolution device includes a dissolution vessel storing a part of culture solution in a culture vessel, a gas supply pipe connected to a carbon dioxide cylinder and supplying carbon dioxide through an end inserted into the dissolution vessel, a gas discharger provided at the gas supply pipe and turning the carbon dioxide into microbubbles, and a mass flow controller controlling a flowrate of the carbon dioxide flowing in the gas supply pipe. Here, a water depth from the gas discharger to a liquid level of the culture solution in the dissolution vessel is set deeper than a water depth of the culture solution in the culture vessel.

The present disclosure includes methods of making a brine solution that include recirculating brine solution to a salt and water hopper from a holding tank. The present disclosure also includes an apparatus for making a solution that includes at least one nozzle assembly positioned inside the lower half of a hopper. The at least one nozzle assembly includes a manifold having at least two nozzles spaced apart. Each nozzle has one or more nozzle outlets that are directed away from the bottom of the hopper (e.g., toward the top of the hopper).

Systems and methods for enhanced filtration and separation of fluid from microorganisms, toxins and other particles in a more efficient manner is provided. The system may include a selectively removeable fitting or replaceable filter media and is suitable for use with liquid dispensing devices such as hydrotherapy jets, shower heads, liquid nozzles, and bathtub faucets.

A system for mixing a liquid with a powder into a solution batch includes a hopper (20) into which said powder is deposited, the hopper (20) having a powder outlet (22) therein. A mix tank (60) is also provided having a liquid supply inlet (62), a recirculation inlet (64), and a solution outlet (66). A mix pump (40) that is in fluid communication with the solution outlet (66), the powder outlet (22), and the recirculation inlet (64) operates to mix and transfer the solution.

An apparatus for dissolving a gas into a liquid includes a liquid inlet for supplying liquid into the apparatus, a gas inlet for supplying gas into the liquid within the apparatus and a venturi arranged to dissolve the gas into the liquid passing through the venturi. The apparatus also includes an outlet for the liquid and dissolved gas downstream of the venturi. At least part of the liquid inlet, at least part of the gas inlet, at least part of the venturi and at least part of the outlet are integrally formed in a single piece of material.

A fluid handling apparatus for ejecting fluid into a tank and draining fluid from the tank comprises: a fluid duct for draining/supplying fluid from/to the tank, the fluid duct configured for fluid communication with a tank opening at a tank bottom; a fluid inlet pipe for supplying fluid to the tank, the fluid inlet pipe extending at least partly through the fluid duct and configured to extend through the tank opening into the tank; a rotary fluid ejection device in fluid communication with the fluid inlet pipe; and a rotary drive shaft extending at least partly inside the fluid inlet pipe, the rotary drive shaft being rotatably connected to the rotary fluid ejection device. Also disclosed is a fluid tank system comprising a tank and a fluid handling apparatus, and a method for mixing beer or wort with solid hops material in a tank by a fluid handling apparatus.
