Methods and systems for carbon sequestration in conjunction with oil and gas operations. Carbon dioxide in the form of nanobubbles is used to supersaturate treated produced water. The supersaturated produced water is then injected into Class II injection wells for effective storage in underground formations in conjunction with enhanced recovery operations or the storage and disposal of produced water from production operations.

An apparatus for a programmable self sanitizing water dispenser apparatus with a digital controller as well as a programmable method for generating ozone for cleaning the reservoir and the water contained within it. The apparatus includes an anti-spill receiver that houses the controller and that can contain a ozone generator.

The present invention relates to an integral system for treating the water for cooling towers and other processes such as reverse osmosis rejection, regeneration of the anionic units of demineralization systems, aircraft blue water and wastewater, in which it is desired to reduce and/or eliminate contaminants such as silica, total, of calcium and magnesium hardness, suspended solids, organic matter and microorganisms, heavy metals, detergents or arsenic, for obtaining a water quality that enables it to be reused in different industrial processes, generating savings in terms of water and chemicals. The system is characterized in that the water to be treated passes through an electrochemical cell with plates of aluminum, iron or some other metal, and, when an electric current is applied at an amperage that allows an optimal current density to yield the aluminum required to form a hydroxide of aluminum, iron or some other metal, which, when reacting with the contaminants present in the water to be treated, forms an iodine that is later separated out from the water, enabling the treated water to be reused by this system, by integrating the processes of filtration and ozonation it enables better water quality to be obtained for reuse in cooling towers, industrial processes, general services, irrigation of green areas or any other use.

The technological innovation in the present invention is that it totally eliminates the silica present in industrial waters, allowing reuse of this water in different processes owing to the quality obtained. In addition to reducing the calcium and magnesium hardness salt concentration, preventing the formation of encrustations and, in cooling-tower systems, making it possible to increase concentration cycles, thereby generating savings of water and chemicals, it reduces microbiological proliferation, which will enable industry in general to replace conventional industrial water-treatment programs with this new technological alternative.

The advantages and benefits of the present invention are that it allows reuse and recycling of 100% of the water that has to be discarded in cooling towers, reverse osmosis rejection, regeneration of anionic units of demineralization systems and wastewater from industry, generating financial savings by allowing reuse of the water that is currently necessary to discard, thereby reducing the quantity of required chemicals essential for cooling towers and wastewater, reducing the impact on the environment caused by water being discarded with contaminants and chemicals content that makes it impossible for it to be reused. Furthermore, it allows the elimination of the contaminants present in t

There is provided a dissolver tube to generate a pressure change to a fluid to change a physical property of the fluid, the tube comprising: a hollow tubular outer body; an inlet cap coupled to the body at an inlet thereof; an outlet cap coupled to the body at an outlet thereof; and a plurality of mesh screens arranged between the inlet cap and outlet cap, wherein each mesh screen has a plurality of micro-holes formed therethrough, each micro-hole having a Venturi structure, thereby to momentarily continuously contract, relax, and shear the fluid passing through the tube.

Disclosed are a method, a device, and/or system of effective and/or safe ozonation of water in a tank through evolved gas control. In one embodiment, a system for effective ozonation of water includes an ozone generator for producing ozone partially in the form of ozone gas, and a disperser. The disperser is configured to receive ozone gas from the ozone generator rising through the water as ozone bubbles disperse the ozone bubbles within the water. The disperser increases a contact time of the ozone and/or distributes dissolution of the ozone in the water. The disperser may include one or more bubble paths guiding the ozone bubbles. The ozone generator may be an electrolytic ozone unit. An electrode may include a proton exchange membrane electrically coupling an anode and a cathode of an electrode, where hydrogen gas generated at the cathode may be vented and/or conveyed to a catalytic decomposition unit.

An apparatus has a tank with an interior for containing water, a nozzle for directing ozonated water out of the spray apparatus, and an electrolytic cell located between the nozzle and the tank. The electrolytic cell is configured to ozonate water as the water flows from the tank to the nozzle. The apparatus also includes a power source for providing electric potential to the electrolytic cell. The tank, nozzle, and electrolytic cell all are part of a single spray bottle or dispenser (e.g., like a soap dispenser).

A method for purification of a water, groundwater and/or soil contaminated with organic impurities comprises steps of injecting an ozone-saturated water into the contaminated water and oxidizing the contaminants by the ozone-saturated water in combination with other purification methods.
