Systems and methods for blending fluids are provided. A blended fluid may be obtained by mixing a first fluid from a first fluid source with a second fluid from a second fluid source. The blended fluid may be pumped by a pump arranged downstream of a point at which the first and second fluids are mixed, wherein no other pumps are upstream of the pump. First and second flow control valves that control the flow rate of the first and second fluids, respectively, are adjusted so as to reach a target flow rate of the blended fluid, the blended fluid having a target blend of the first fluid and the second fluid.

A fluid injection system includes a container and fluid injection device. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and has a first end and a second end defining a ramped surface therebetween. The shroud redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives product from the container. The first end of the shroud includes a step defining a notch in fluid communication with the diverter port. The second end defines a recess in fluid communication with the injection port.

A fluid injection system includes a container, fluid injection device and a fertigation basket. The fluid injection device includes a housing having a flow tube having an inlet end and an outlet end. A shroud is positioned between the inlet end and the outlet end and redefines at least a portion of the fluid pathway as a constricted fluid pathway. A diverter port is between the inlet end and the shroud and diverts a portion of the inlet fluid into the container. An injection port is between the shroud and the outlet end and receives an injection tube. The fertigation basket holds dry product which is dissolved into the container to be drawn out of outlet end via the injection tube.

A water filter apparatus for use in filtering particles out of a water supply is provided. The apparatus comprises a multiple layered mesh type filter housing having a top proximal end and a bottom distal end, wherein the top proximal end comprising dual projected passageways adapted to be connected with an upstream water supply and for the addition of the soap powder, solution and detergent to the upstream water prior to the filtration process, The cup or cone shaped funnel is attached, either at the side or at the top of the said top proximal end of the purifier as shown in figs. The funnel act as the passage for detergent or soap powder, mixed inside the purifier before entering the filter. The device enables the mixing of the soap powder or detergent with the upstream water prior to the process of filtration executed by the mesh arrangement. The water and soap powder combination provided in the form a powder solution is in-let into the mesh arrangement for filtration which avoids the formation of scaling in the washing machine and the formation of the white patches in the washed clothes. The filtering device comprises at least six filtering meshes of varied micron sizes sandwiched between the top proximal end and the bottom distal end. The meshes are arranged in such a fashion as to comprise the larger micron sized mesh closer to the top proximal end with correspondingly decreasing micron sized meshes to the bottom distal end. The more important aspect of the invention being that the water purifier is capable of cleaning the filter and cartridge through backwash or reverse wash process by connecting the said purifier arrangement in the upside down position to the said tap water inlet.

The present invention discloses an integrated composite overload injection system and a working method thereof. The feeding mechanism preliminarily mixes water with a main agent and an auxiliary agent of an intelligent energy-gathered oil-displacing agent according to the ratio, the outlet of the feeding mechanism is communicated with the input port of the composite overload mechanism through a pipeline, the composite overload mechanism stirs, mixes, dissolves and overload ripens the preliminarily mixed solution to form mother solution, the mother solution is input from the output port of the composite overload mechanism to the inlet of the booster pump through a pipeline, the booster pump injects the boosted mother solution into the mixer, the mixer mixes the mother solution and the diluted high-pressure water and injects it into an oil-water well, and the power shafts of the composite overload mechanism and the booster pump are both driven by the driving mechanism.

First and second flow control valves that control the flow rate of the first and second fluids, respectively, are adjusted so as to reach a target flow rate of the blended fluid, the blended fluid having a target blend of the first fluid and the second fluid.

A rehydration capsule, and a method of rehydrating media within such capsule, the capsule including a capsule body having an inlet and an outlet, a member proximate the inlet having at least an opening therethrough, a filter proximate the outlet, and a hollow flow tube corresponding to each of said at least one opening mounted to the member and having an inlet at one end aligned with the at least one opening and having at least one opening through its body.

A sieve-like filter unit, especially for a cartridge-shaped receptacle, which is arranged on a connecting port/connector of the receptacle and is designed to withhold undissolved powder and/or solid particles present in the receptacle, comprising at least two openings each being composed of at least two connected part recesses, wherein each individual opening in its entirety is formed to be extending in a non-linear manner.

A method of preparing a liquid product includes: providing a box or carton containing a predetermined quantity of at least one powder-based constituent and a predetermined quantity of at least one liquid additive in an additive container; placing the powder-based constituent in a housing of a dissolution generator, adjacent a screen assembly; using a pressure mechanism to apply a pressure to the powder against the screen assembly; spraying at least a solvent at the powder from a spray nozzle through the powder support screen assembly, thereby dissolving exposed powder and producing a solution; discharging the solution into a mixing chamber; using the solvent, purging the at least one liquid additive from the respective additive container into the mixing chamber; mixing the solution and the at least one liquid additive in the mixing chamber so as to form the liquid product; and dispensing the liquid product from the apparatus.
