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.

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.

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 provides a system for imparting electromagnetic energy into drinking water or aqueous potables and foods, comprising: a generator unit for generating a driving signal having a frequency to maintain a nature or an activity of microorganisms in living forms; a power supply unit for providing a voltage current to the generator unit to drive the generation of the driving signal; one or more inductor coils coupled to the generator unit to receive the driving signal, such that an electromagnetic field operating with the varying frequency is generated; and an electromagnetic wave-permeable container for containing the drinking water or the aqueous potables and foods wherein the drinking water or the aqueous potables and foods is subject to the generated electromagnetic field to allow permeation of the varying frequency electromagnetic wave through the container into the drinking water or the aqueous potables and foods to acquire electromagnetic energy. The invention also provides a method for imparting electromagnetic energy into drinking water or aqueous potables and foods.

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 method of extracting water from sludge, wherein the sludge includes a magnetic ballast, wherein the sludge is positioned on an interface. It includes applying a magnetic treatment to the magnetically-ballasted sludge to extract water from the sludge.

The present invention provides a method for treating water containing pollutants, comprising the steps of 1) bringing said water in contact with magnetoelectric particles so that the pollutants in the water come into contact with the surfaces of magnetoelectric particles; 2) applying a magnetic field to the magnetoelectric particles so as to generate electric charges on the surface of said magnetoelectric particles, wherein said electric charges on the surface of said magnetoelectric particles cause redox reactions to occur which oxidize said pollutants in the water. Also provided arm water cleaning reactors which can be used to perform the method of the present invention and water cleaning assemblies which use any of said water cleaning reactors.

There is provided a fluid treatment separator and a method of treating fluid such as tailings from tailings ponds resulting from oil sands production. A fluid treatment separator may be used for treatment of a mixture containing at least oil and water. The separator includes a mixing chamber, an inlet and at least one outlet. The mixing chamber defines a flow path between the inlet and the at least one outlet. The inlet includes a nozzle arranged to introduce turbulence to the mixture along the flow path. At least one magnet is arranged to apply a magnetic field to the mixture along the flow path.
