Embodiments of the present disclosure can include a system for harvesting salt and generating distilled water from at least one of a produced water and salt water, comprising. A direct steam generator (DSG) can be configured to generate saturated steam and combustion exhaust constituents from the at least one of the produced water and salt water. A separation system can be configured to separate the salt from at least one of the saturated steam and combustion exhaust constituents in brine form or solid form.

The present invention relates to a method for liquid media purification, such as potable water, where biological and chemical composition of fluid to be purified is enhanced. The invention also relates to a device for carrying out said method. According to the invention, the liquid is purified by removing coarse particles from said liquid on first filtering means (2), dispersing the liquid with at least one nozzle (3) into a working chamber (4), where it is exposed to a working pressure and gas or gas mixture is introduced in the chamber from at least one inlet aperture (5).

The present disclosure provides a particulate matter comprising a combination of crystalline manganese oxide and amorphous manganese oxide, the crystalline form being present and forms passages throughout a cross section of said particulate matter, wherein said crystalline form define a specific surface area that is greater than the outer surface of said particulate matter. Also provided herein is a process for removing chemical contaminants from flowing water making use of the particulate matter and a device and a system comprising the particulate matter.

Provided is an ultrafine bubble generation device for aquaculture or wastewater treatment with which it is possible to efficiently cause ultrafine bubbles to be dissolved or to coexist, and to increase the concentration of a gas in the liquid. An ultrafine bubble generation device for aquaculture or wastewater treatment provided with a channel for channeling a liquid, a compression device for pumping a gas into the channel, and a bubble generation medium for releasing the gas pumped by the compression device as ultrafine bubbles into the liquid in the channel, wherein the bubble generation medium is formed from a carbon-based porous material and is disposed so as to be horizontal or below horizontal with respect to the direction of flow of the liquid in the channel.

Disclosed are methods, apparatuses and systems for the remediation of contaminated soils, groundwater, water, and/or waste using a combination of reagents. The disclosed methods may be used to treat various recalcitrant halogenated substances, such as perfluoroalkyls and polyfluoroalkyls. Particular combinations of reagents that may be used in the disclosed methods include but are not limited to: (1) persulfate, oxygen and ozone; (2) persulfate, salt, oxygen and ozone; (3) persulfate, phosphate, and/or oxygen; (4) persulfate, phosphate, oxygen and ozone; (5) persulfate, phosphate, salt and oxygen (6) persulfate, phosphate, salt, oxygen and ozone; (7) oxygen and salt; and (8) air and salt. The disclosed methods may enhance destruction of organic contaminants in the liquid phase and may also control the rate of aerosol or foam formation relative to the rate of chemical oxidation and/or reduction/transfer.

A magnetization purifying device is provided. At least one or more accommodation spaces formed inside a housing unit along a preset depth or a width status are formed for accommodating a preset amount of magnetization purifying devices having corresponding status, a covering unit having an outwardly-extended engaging segment is provided and capable of being rotated for being matched with an opening formed at one end of the housing unit, another end of the housing unit capable of accommodating the magnetization purifying devices is formed with a recessed engaging segment, so that the magnetization purifying device can perform a predetermined rapid circulating magnetic force line cutting operation to introduced water or air, thereby enabling the water or air fully magnetized and discharged to be provided with anticipated pure oxygen and negative ions, thus the dissolved oxygen in water in a predetermined route, for example an aquaculture pond, can be increased.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

A magnetic fluid treatment system chamber for treating water for agricultural and other uses includes a fluid inlet and a fluid outlet opposite the fluid inlet. A fluid flow path runs from the fluid inlet to the fluid outlet. A plurality of ferrous metal rods is located circumferentially-spaced about the flow path. The ferrous metal rods are parallel to the flow path. A plurality of axially oriented magnets each has a north face and a south face. Each of the faces of the axially oriented magnets abuts one of the ferrous metal rods.

The present invention concerns a method for treating the production water originating from enhanced hydrocarbon recovery, and containing one or more water-soluble polymers and Fe.sup.2+ ions, consisting of at least partially oxidizing the Fe.sup.2+ ions by introducing at least one reaction activator and oxygen into said production water, the molar ratio of introduced oxygen to Fe.sup.2+ ions being less than or equal to 0.25.

The invention relates to a process for treating a waste lye of a lye scrub in which the waste lye is fed with oxygen or an oxygen-containing gas mixture and steam to an oxidation unit (1) and in the latter is subjected to a wet oxidation for a reaction time period at a first temperature level and a first pressure level, a three-phase component mixture, which comprises a gas phase, a liquid phase and solid particles, being removed from the oxidation unit (1) and subjected to a cooling and phase separation. It is provided that the three-phase component mixture in an unchanged composition is first subjected to an expansion from the first pressure level to a second pressure level and thereby cooled down to a second temperature level, and that the three-phase component mixture expanded to the second pressure level and cooled down to the second temperature level is subsequently subjected at least partly to a further cooling to a third temperature level and after that to a phase separation. A corresponding installation is likewise the subject of the present invention.
