Rotary in-line pumps as disclosed herein overcome drawbacks associated with known adverse flow conditions that arise from flow of certain types of materials through a material flow conduit. Such rotary in-line pumps provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a cyclonic flow (i.e., vortex or swirling) profile. Advantageously, the cyclonic flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow. Such cyclonic flow profile provides a variety of other advantages as compared to a parabolic flow profile such as, for example, increased flow rate, reduce inner pipeline wear, more uniform inner pipe wear, reduction in energy consumption, reduced or eliminated slugging and the like.

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 invention relates to a device (50) for supplying air to a suction side (12) of a pump (10) of a wiper system (100), said device (50) comprising a suction channel (60) for sucking in air, said suction channel (60) being able to be connected to the suction side (12) of the pump (10). Provision is made that the device (50) is realized as a component separate from the pump (10) and comprises a connection area (52) for connecting the device (50) with a supply container (14) for washer fluid (3) and having an additional connection area (54) for a suction nozzle (24) of the pump (10), and that a check valve (62) is disposed in the suction channel (60), said check valve (62) being designed to open and close as a function of a negative pressure (P) on a suction nozzle (24) of the pump (10), whereby when the said check valve (62) is opened air can enter the area of the suction nozzle (24) of the pump (10), and when the check valve (62) is closed no air is sucked in. 20

The present invention relates to a micro-bubble pump apparatus for a water treatment, and the micro-bubble pump apparatus for a water treatment comprises: a motor for generating rotatory power; and a micro-bubble pump connected to the motor and for mixing a feed liquid which flows into one side thereof and a feed gas which is injected into the other side thereof.

A system for producing a liquid with gas bubbles. The system has an eductor to mix a liquid stream and a gas stream to a form of a liquid-gas mixture and a mixing column with a stack of filling layers to reduce a size of gas bubbles within the liquid-gas mixture. The stack of filling layers has a plurality of porous layers separated alternately by plate layers and ring layers.

Increased control and efficiency over the wastewater purification can be achieved through creating conditions that allow the operator to selectively prioritize the digestive function of microorganism in the activated sludge. The gas-dispersion return sludge is created using pure oxygen or oxygen containing trace amounts of ozone as a reactive gas, which is blended with return sludge to create a mixture of gas and liquid, which is passed through an atomizer or a cavitation pump to instantly render the reactive gas to an ultra-fine bubble state. At least a portion of the ultra-fine bubbles dissolve within the gas-dispersion return sludge, activating the dormant microorganisms. Due to a complete or an almost complete absence of biodegradable material in the gas-dispersion return sludge, the microorganism prioritize their digestive function, and when exposed to biodegradable pollutants present in wastewater, digest the pollutants using biochemical pathways different from the ones used in nature.

A system and method for pumping fluid using a set of interconnected pump cassettes is disclosed. Each of the pump cassettes can receive a first solution in a first pumping chamber and each of the pump cassettes can receive separate second solutions in respective second pumping chambers, so that the first solution can be mixed with the separate second solutions, each said mixture capable of being placed in separate containers. The system includes a control assembly for operating each pump cassette, each pump cassette having a flexible membrane to pump fluid into and out of the pumping chambers, and each pump cassette configured for mating with a base unit that provides positive or negative pneumatic pressure to the flexible membrane.
