The physical water treatment device, in particular in a flexible water inlet (1), comprises at least one pair of electrodes (2) for water galvanization and at least one means for inserting and fixing the electrodes (2). The means for inserting and fixing the electrodes (2) together with the electrodes (2) form an integral body (3), the resulting shape of which is adapted for the insertion into the flexible water inlet (1). The integral body (3) completely blocks the flexible water inlet (1) and is hollow so that the water flowing through the flexible inlet (1) flows through the electrodes (2) of the integral body (3). The electrodes (2) form a flow-through galvanization system in the integral body (3).

An efficient, cost-effective, and efficacious technique for removing coal ash and other pollutants from waterways, ponds, marshes, holding tanks and other water sources and supplies. An apparatus comprising an open cage including electromagnets and/or permanent magnets and/or electrodes is supplied with electrical power to extract materials such as rare earth elements and/or heavy metals. The materials levitate to the surface, forming a shiny while leaving water substantially free of such materials.

There is disclosed, a desalination apparatus making use of a particles including covalently bonded functionalized magnetic nanoparticles coupled to a complexing agent. For example, the complexing agent may include a crown ether. The particles are optionally used for removing salt from water, for example sea water. The apparatus optionally includes a magnet for magnetic filtering, concentrating and/or removing the particles and/or contaminant (e.g. salt). In some embodiments, the salt is then separated back from the particles using UV light. The remaining unclarified water may be washed out with the contaminant and/or used for salt production and/or disposed of (e.g. dumped back to the sea). Optionally, the particles are regenerated. For example, the regenerated particulars may be reused for further desalination steps (e.g. further salt removal from the clarified water) to clarify new input water.

The present invention relates to systems and methods for cleaning materials, such as flooring and upholstery. In some cases, the systems and methods use an electrolytic cell to electrolyze a solution comprising sodium carbonate, sodium bicarbonate, sodium acetate, sodium percarbonate, potassium carbonate, potassium bicarbonate, and/or any other suitable chemical to generate electrolyzed alkaline water and/or electrolyzed oxidizing water. In some cases, the cell comprises a recirculation loop that recirculates anolyte through an anode compartment of the cell. In some cases, the cell further comprises a sensor and a processor, where the processor is configured to automatically change an operation of the cell, based on a reading from the sensor. In some cases, a fluid flows past a magnet before entering the cell. In some additional cases, fluid from the cell is conditioned by being split into multiple conduits that run in proximity to each other. Additional implementations are described.

A method for advanced treatment and reuse of biochemical effluent from chemical wastewater comprises following steps: (1) preparing a highly-loaded Fe.sub.3O.sub.4 magnetic resin by spray suspension polymerization; (2) using the magnetic resin prepared in Step (1) for advanced treatment of the biochemical effluent from chemical wastewater and adding 3˜5 mmol/L H.sub.2O.sub.2 into the biochemical effluent from chemical wastewater for a mixed reaction of 60˜600 minutes; (3) separating solid from liquid firstly in the mixed wastewater after being treated in Step (2), and then disinfecting the separated biochemical effluent from chemical wastewater.

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 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.

A water treatment device and methods of treating water such as cooling tower water, swimming pool water, and hot tub or spa water, are described. The water treatment device utilizes ultraviolet radiation, a magnetic field, and ozone fortified air to treat the water, typically resulting in reduced microbial contamination and reduced alkalinity in cooling tower water. Cooling tower water may consequently be run at higher cycles of concentration while reducing or eliminating deposition of minerals on cooling tower components. Swimming pool water and hot tub water treated with the water treatment device typically requires less chlorine, and chlorine levels are typically more stable than without the device.

A magnetic separation device includes magnetic separation units in each of which a flow direction of raw water in a separation vessel is set to the same direction as a rotation direction of a magnetic drum. In the left-side magnetic separation unit, a raw water feeding channel is connected to the left side of the separation vessel, so that the raw water flows from left to right in the separation vessel and the treated water flows out of a discharge channel. The magnetic drum rotates in a counter clockwise direction. In the right-side magnetic separation unit, the raw water feeding channel is connected to the right side of the separation vessel, so that the raw water flows from right to left in the separation vessel and the treated water flows out of the discharge channel. The magnetic drum also rotates in the clockwise direction.
