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.

The present invention relates to a portable water de-ionizer including a vertically elongated tubular housing for receiving a water container, i.e., a bottle being filled with water to be treated and a base being anchored to the bottom end of housing. The tubular housing is provided with a coil being circumferentially wound on the outer surface thereof to form a plurality of turns. Further, the base accommodates a SMPS circuit for providing a required voltage supply to the coil. The bottle filled with the water is placed within the tubular housing. The electronic circuit is electrically connected to the coil wound around the tubular housing and communicates a succession of radio frequency signals to the coil that create an electromagnetic field in water filled within the tubular housing. The electronic field continuously de-ionizes the water filled in the bottle while the bottle is placed within the tubular housing.

A method and reactor are disclosed for separating and removing heavy metals from wastewater using a sulfhydryl-modified nano-magnetized activated carbon. The method includes the steps of preparing a sulfhydryl-modified nano-magnetized activated carbon first; introducing heavy-metal-containing wastewater into a reactor which is equipped with a stirrer and keeping stirring, and then adding the sulfhydryl-modified nano-magnetized activated carbon, continuously stirring for a reaction; after reacting for a period, precipitating under a magnetic field generated by a magnet separator, discharging the resulting supernate, and then discharging the precipitated sludge.

An in-line fitment for connection of a filter to a pipe includes first and second fluid-carrying portions and a non-fluid-carrying spacer. Each fluid-carrying portion includes a socket for receiving an open end of a pipe and a connector for connection of the filter. A screw compression fitting is provided on each of the sockets of the first and second fluid-carrying portions for forming a sealed connection with the open ends of the pipe. The socket of the first fluid-carrying portion has a pipe receiving depth greater than that of the socket of the second fluid-carrying portion for enabling movement of the fitment parallel to the pipe when engaged with one of the open ends of the pipe. The sockets of the first and second fluid-carrying portions are positioned on a common axis and facing away from each other when the fluid-carrying portions are linked by the spacer.

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.
