The present invention describes a PEF (pulsed electric field) chamber 1 intended for treating a flow with electric field pulses, said PEF chamber comprising a PEF treatment tube 2 and opposite electrode units 3, 4, wherein said opposite electrode units 3, 4 each has one flow receiving end 5a, 5b and one flow exit end 6a, 6b, wherein the PEF treatment tube 2 comprises exit flow portions 7a, 7b arranged subsequent to the flow exit ends 6a, 6b of the electrode units 3, 4 in the intended flow direction, and thus functioning as an extension of the opposite electrode units 3, 4 in the intended flow direction, wherein the exit flow portions 7a, 7b of the PEF treatment tube 2 are arranged to provide a geometrical narrowing 20 subsequent to the flow exit ends 6a, 6b.

A magnetic water filter assembly with a removable lighter weight lower section to permit access to the internal components of the filter assembly. The removable lower section allows the servicing and/or replacement of the internal filter as well as cleaning of the assembly. The lighter weight lower section reduces the stress placed on the surrounding plumbing components, including the piping/tubing that couples to the filter assembly.

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.

A medium for fast, selective oil-water separation and/or oil absorption includes steel wool modified with a polymer a polymer or a polymer mixture. The polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water. The polymer or the polymer mixture includes polydimethylsiloxane, polytetrafluoroethylene, polyvinylpyrrolidone, or a combination thereof. The solution immersion method used to synthesize the medium requires only a single, simple step and affordable materials and, as a result, is easy to scale up.

Embodiments of the present disclosure include systems and methods for enhancing the performance and efficiency of separation processes. The methods include flowing a fluid through a processing zone defined by an antiferromagnetic portion of a conduit and, as the fluid flows through the processing zone, exposing the fluid to a magnetic field produced by oscillating electromagnetic waves, wherein the direction of the magnetic field is generally counter to the direction in which the fluid is flowing. The systems include magnetic treatment units, separation systems, and the like.

A method of synthesizing a medium for fast, selective oil-water separation and/or oil absorption comprises providing a toluene solution containing a polymer or a polymer mixture; immersing porous wool-like structure (PW) in the toluene solution for a period of time; and removing the immersed PW from the toluene solution, and heat-treating the immersed PW to obtain the medium comprising polymer-modified PW, wherein the polymer or the polymer mixture is adapted such that the medium is a superwetting material that is superhydrophobic and superoleophilic under water or salty water.

A fluid-treatment apparatus has a coil structure, a first circuit formed by a rectifier diode and a capacitor in parallel connection, a second circuit formed by a first coil wound on a first section of the coil structure and a second coil wound on a second section of the coil structure, and a third circuit formed by a third coil wound on the second coil and a fourth coil wound on a third section of the coil structure. The first and second coils have a first winding direction, and the third and fourth coils have a second winding direction opposite to the first winding direction. The first and second coils are a first alternate-current (AC) input terminal and the anode of the rectifier diode. The third and fourth coils are connected to a second alternate-current (AC) input terminal and the cathode of the rectifier diode.
