The invention in at least one embodiment includes a system for treating water having an intake module, a vortex module, a disk-pack module, and a motor module where the intake module is above the vortex module, which is above the disk-pack module and the motor module. In a further embodiment, a housing is provided over at least the intake module and the vortex module and sits above the disk-pack module. In at least one further embodiment, the disk-pack module includes a disk-pack turbine having a plurality of disks having at least one waveform present on at least one of the disks.

A vortex flow inducer has inducer body with an interior end, an outer end and a length extending there between, and a longitudinal axis extending between the interior and the outer ends. A flow passage extends between the interior and outer ends of the inducer body. The flow passage has an inlet at the outer end and an exit at the interior end. The flow passage is swept latterly toward a side of the inducer body in a direction from the outer end toward the interior end such that the exit is latterly offset from the longitudinal axis. The interior end of the inducer body has a concave curvature. The swept flow passage and the curved interior end induce a vortex flow in a fluid flowing through the flow passage as it exits the flow passage and into a flow passage of a conduit the that extends at an angle relative to the longitudinal axis of the inducer body.

Plasma discharges and electromagnetic fields may be applied to a liquid, such as water, for desalinization purposes and to treat unwanted material in the liquid.

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 senor 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.

Fluid treatment systems and components are provided for a removal of solid matter from water or other fluids in which a chemical or chemicals may be introduced into the fluid under pressure to coagulate and/or conglomerate the solid materials and cause them to be dropped out of the treatment system and be removed. The fluid treatment system can include: an equalization chamber receiving a wastewater; a clarification chamber receiving a partially separated water from the equalization chamber; a mixing tube having an inlet end and an outlet end; and a sludge detector.

A method of evaporating a fluid is provided. The method comprises forming a flow with toroidal vortices in the fluid, such that the fluid is exposed to alternating flow velocities and alternating pressures, thereby increasing evaporation of the fluid. A method of precipitating salt out of an aqueous solution is also provided. The method comprises forming a flow with toroidal vortices in the aqueous solution, such that the aqueous solution is exposed to alternating flow velocities and alternating pressures, thereby initiating precipitation of salts from the solution.

Waste water is remanufactured with ozone in a series of mixing vessels. The ozone is dispersed to both a top and a bottom portion of each mixing vessel, but in different amounts. This creates an electrical potential difference across the height of each mixing vessel which significantly improves the oxidation of organic carbon-based impurities and eliminates H2S and bacteria. Sludge and solids floating to the top of each mixing vessels are removed, as well as sludge and solids settling to the bottom of the mixing vessels. When oil and gas well waste water is treated in this manner, the resulting treated water is purified and has a high salt content suitable for oil or gas well injection.

A device for treating a flow of water having a chamber (1) through which the flow of water passes. in the chamber (1), a voltage with alternating polarity is fed to two electrodes (15a, 15b) of at least one electrolysis device, whereby particles of the electrode material are released to and entrained by the flow of water. The particles in the flow of water are mixed in at least one nozzle (45) of a vortexing device.
