The invention relates to a shower arm with a torus regulator and a magnetic ring that is comprised of a body (1) with a body head (25), a bell (2), a cover (3), a torus (4), a mixing element (5), a ring (6), a pin (7) and a barrier (9) on the cover, a barrier (8) and a nozzle (10) on the bell, a cavity (11) for water inlet, an inlet (12) of water into the shower head (25), a space (13), a gap (14) on the mixing element, a chamber (15), gaskets (16) and (17), a thread (18), a space (19) for directed flow, pins (20) and a groove (21) on the ring, a groove (22) on the bell, a thread (23) for connecting a hose, a support surface (24) a magnetic ring (26) and an output spray (27) of water and air. When the water circulates within the space (19) underneath the torus (4), negative pressure—vacuum occurs from both the internal and the external sides of the torus cross-section that conditions suction of the air from the chamber (15) of the cone of the bell (2). This air is suctioned through the nozzle (10). In the space below the mixing element (5) the air and the water swirl which alternately enter into the air/water mixture and form a wide conical spray (27). The bell is provided with the groove (22), into which the ring (6) with pins (20) is tightly inserted. The pins are made from a soft material and serve for mechanical massage of the skin and the crown of the hair. On the other side in the ring there is the groove (21), into which the magnetic ring (26) is inserted. Its role is to normalize the water crystals and to arrange them into a natural shape. The nozzle (10) for spray outlet has an orifice large enough in order not to clog due to impurities in the water and limescale.

The present disclosure relates to a filter, which comprises a housing, a protective bushing, a magnetic bar and a filter screen. The protective bushing, the magnetic bar and the filter screen are disposed in the housing. The protective bushing comprises a cavity and a channel. The channel is disposed along the axial direction of the cavity. The advantageous effects of the filter according to the present disclosure lies in that: the magnetic bar inside the filter can adsorb metal impurities in the water in the channel; and the channel is in S shape which can increase the length of the flow path of the water so that the metal impurities in the water can be guaranteed to be sufficiently adsorbed by the magnetic bar; and the filter screen can filter out non-metal impurities in the water. An exhaust valve provided at the top of the protective bushing can keep the balance between the air pressure inside the filter and the air pressure outside the filter, which can ensure that the water can flow out and in smoothly. The filter is attached with an operating handle. If the user wants to disassemble the filter to clear up the metal impurities and non-metal impurities in the filter, he can disassemble the filter by means of the operating handle without the need of professional operator, which is convenient and simple.

A fluid treatment apparatus includes a ferrite assembly, a driver, and an oscillator circuit. The ferrite assembly is arranged in use to be capable of surrounding a conduit containing fluid to be acted on. The driver is arranged to generate a pulsed current to which the ferrite assembly is subjected whereby the driver is electromagnetically coupled to the ferrite assembly. The oscillator circuit is electromagnetically coupled to the ferrite assembly, and in response to the pulse generated by the driver, causes an oscillating signal to be generated which gives rise to an electromagnetic field which acts on the fluid in the conduit.

The mixing system for ready-to-use flush solutions is characterized by an RO system, a mixing unit that is connected to the RO system and that contains a mixing chamber, to which high-purity water can be fed from the RO system and flush solution concentrate can be fed from a concentrate source, and a flush solution link connector, wherein the RO system and the mixing unit form a filling station, a mobile flush solution container that contains a pressurized container that receives a flush solution bag that can be coupled to the flush solution link connector of the mixing unit, and a computer and control mechanism for all measurement and monitoring tasks during the local production of a flush solution, wherein the mobile flush solution container and the filling station are provided with sensors by means of which wireless communication is made possible between the mobile flush solution container and the filling station.

Some described examples relate to an apparatus for removing magnetically active particles from a fluid. The apparatus comprises at least one vessel for receiving a fluid comprising magnetically active or ferrous particles, and at least one electromagnet operable to produce a magnetic field within the vessel to act on the magnetically active or ferrous particles in use.

A method and apparatus for the removal of both suspended and dissolved contaminants in a fluid stream, including but not limited to heavy metals, organics, inorganics, hydrocarbons and others. The method combines passing an aqueous fluid stream through an electromagnetic field, an ozone/oxygen venturi injector for oxidation and through a horizontal flow and vertical fall within a horizontal plate maze unit of alternately electrically charged plates. The plates are charged alternately to be cathodes and anodes, respectively. A framework to mount and support membranes, dividers or separators, as may be required to enhance special treatment of the fluid stream, is optionally provided.

A strainer (101) for use in fluid piping. The strainer (101) comprises a body (102) for connection to a fluid piping inflow conduit (201) and to a fluid piping outflow conduit (202). The body (102) defines an interior chamber (103), a fluid inlet port (104) and a fluid outlet port (105). The body (102) defines a fluid flow path (106) between the fluid inlet port (104) and the fluid outlet port (105) that extends through the interior chamber (103). The strainer (101) comprises a screen collector (107) that is removably locatable in the body (102), within the fluid flow path (106). The strainer (101) further comprises a permanent magnet collector (102) that is removably locatable in the body (102). The strainer (101) may be used in fluid circuit piping of a heating or a cooling system.
