A medical device includes: a hollow body part formed in a predetermined bent shape; a head part provided at a tip portion thereof with a discharge port for discharging cleaning water and detachably coupled to a front end of the body part; a connection part connected to a shower hose and a rear end of the body part and provided with a control valve for controlling water supply, a water flow rate and a water pressure; a water purification tube built in the body part and provided with leakage preventing grilles at both ends thereof; and a purified water discharge part provided inside the head part and configured to remove foreign substances in the water by using a filter.

Systems and methods are disclosed for cleaning and sterilizing fluids and other materials. In one implementation, one or more emitters are submerged within a fluid and emit electromagnetic waves having a variable frequency. The frequency of the electromagnetic waves is swept across a frequency range to neutralize bacteria, viruses, and other pathogens in the fluid. The emitters may be submerged within a fluid reservoir and/or within the interior of an enclosed fluidic path (e.g., a pipe). Solid materials may be sterilized by immersing the solid materials within the fluid of such a fluid reservoir. In another implementation, electromagnetic waves may be applied to one or more wires that are wrapped around an exterior wall of a pipe. The frequency of the electromagnetic waves may be varied across a frequency range, resulting in scale and other materials being cleaned from the interior wall of the pipe.

In one embodiment, a treatment system for removing dissolved contaminants (e.g., arsenic) from a contaminated fluid (e.g., water) utilizes in-situ generation of adsorption filtration media or reactive components. Corrosion materials (e.g., iron oxide complexes) that serve as the adsorption filtration media or reactive components are generated by supplying a flow of contaminated fluid, and injecting air, into a generator vessel containing pieces of an oxidizable source (e.g., zero-valent iron spheres). The pieces of the oxidizable source are agitated to release particulates of corrosion materials from their surface into solution with the contaminated fluid. Simultaneous to the ongoing generation of corrosion materials, dissolved contaminants in the contaminated fluid are adsorbed on the corrosion materials. New particulate compounds generated by adsorption of the dissolved contaminants on the corrosion materials precipitate from the solution, and are filtered out, thereby removing the contaminants, and yielding treated fluid (e.g., potable water).

Devices and methods are provided for in-line water treatment using strong magnetic fields to influence corrosion, separate toxins, suppress bacteria and bio-fouling, as well as inhibit or greatly reduce mineral scaling due to fluid flow in or around equipment components. For example, a device is provided for applying a magnetic field to a portion of tubing through which a fluid flow, such as water, is conveyed. The device includes a number of links joined together via detachable pivoting connections, such that links may be removed and/or links may be added, thereby allowing a diameter of the device to be adjusted so as to accommodate larger or smaller piping, as necessary, for retrofitting applications. The use of magnetic treatment of fluids such as water may allow extended cycles of operation with higher concentration of mineral salts without the use of chemical scaling suppressants.

The present invention relates to the field of water environment treatment, and particularly discloses a method for carrying out whole-process treatment on phytoplankton. The method comprises: enabling a water body in the natural environment to first pass through a filtering device to remove large-sized particles in the water body; enabling the filtered water body to pass through a water pipe provided with multiple stages of permanent magnets to be subjected to pre-magnetization; then enabling the water body subjected to pre-magnetization to enter an equalization tank to be subjected to homogenization and/or flocculating sedimentation to separate phytoplankton and suspended particles in the water body; then for different growth phases of the phytoplankton, applying different magnetic field intensities for inhibiting and even directly killing the phytoplankton to implement optimization of cost and effects; and finally, carrying out aeration oxygenation on the magnetized water body and releasing the water body subjected to aeration oxygenation into the natural water environment.

A water purification system, a water dispenser and a washing basin applying the same for purifying a raw water to be treated without filtering to a usable fresh water. The water purification system includes a water filtering device coupled to a water intake to filter a raw water to be treated; a first water storage tank coupled to the water filtering device for storing the raw water after being filtered; a nebulization device coupled to the first water storage tank for nebulizing the raw water after being filtered into a water fog; a condensation device coupled to the nebulization device for condensing the water fog; and a second water storage tank coupled to the condensation device for storing a recycled water generated by condensing the water fog.

A submerged plasma generator includes: a reactor inside of which a flow path, through which a working fluid passes, is formed along a lengthwise direction; and a dielectric insert which is disposed in the flow path so as to define the flow path into one space and the other space, and has formed therein a through-hole to generate micro-nano bubbles by cavitation in the working fluid fed into the one space of the flow path, and includes, a metallic catalyst which undergoes friction with the working fluid flowing through the through-hole and releases electric charges of the same polarity to the micro-nano bubbles to collapse the micro-nano bubbles and generate plasma; in which the other space of the flow path in which the working fluid ionized by exposure to the plasma travels is formed in an oval structure.

The invention relates to a fluid treatment device comprising a stirring element and at least one magnetic device. The stirring element has a plurality of flutes within its central portion, and the magnetic devices are placed around the stirring element. The device can further comprise a UV irradiation module and an on-line analysis module.

Described herein is a flow-through application and system that utilizes a nanoparticle technology, which is modular and scalable, that can be utilized to recover a contaminant from water using an attendant pump and in-line sensors along with magnets and ultrasonic energy to separate magnetic nanoparticles from an aqueous mixture and to further separate recovered contaminant from contaminant-adsorbent nanoparticles. The contaminant can include an organic contaminant, such as an oil.

A magnetization device includes an outer casing, a base, a rotatable hood, an object-carrying seat, and a drive mechanism. The rotatable hood includes a receiving space. The rotatable hood has a circumferential wall that includes a pair of magnets mounted thereto, with one N pole and one S pole of the magnets being pointing toward the receiving space of the rotatable hood to induce magnetic lines of force and a magnetic field therebetween. The object-carrying seat is disposed in the receiving space of the rotatable hood to support a magnetized object. The drive mechanism drives the rotatable hood to rotate around and outside the magnetized object, such that the magnetized object is kept stationary and the magnets, and thus the magnetic lines of force and the magnetic field, are driven by the rotatable hood to rotate around the magnetized object.
