Abstract: A fluid treatment tank for an aeration filter has an air blocker separating a chamber in fluid communication with a control valve of the filter from a pocket of air above the liquid in the tank and the control valve. The air blocker contains a volume of liquid that acts as a trap that prevents or at least inhibits air in the pocket from backing up into the chamber. Contact between the control valve and air is dramatically reduced. The air blocker may comprise a baffle that directs any air flowing through the air blocker downwardly and then back upwardly before the air can escape the air blocker.

Abstract: 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 Fe2+ ions, consisting of at least partially oxidizing the Fe2+ ions by introducing at least one reaction activator and oxygen into said production water, the molar ratio of introduced oxygen to Fe2+ ions being less than or equal to 0.25.

Abstract: Disclosed is an apparatus that both makes ozone gas and enables the creation of AOPs in the fluid flowing up the lift tube. The ozone gas and UV radiation are produced by the same UV generating ozone lamps. The apparatus can easily be connected to and becomes part of a lift tube. The apparatus enables pressurized air supplied by an air pump to be partially converted into ozone as the air flows by the UV lamps. This “ozonated air” is then released into a fluid by a diffuser placed in a lift tube below the apparatus. The ozonated bubbles, in turn, create an ozonated fluid that flows up the lift tube and through the apparatus preferably through a specially designed quartz tube that is matched to the size of the lift tube.

Abstract: The present embodiments generally relate to the treatment of produced water such as produced water resulting from an industrial process such as one involving the use of copious amounts of water and the addition of one or more polymers such as viscosifying or thickening polymers, in particular enhanced oil recovery processes or another processes resulting in polymer flooded produced water. These treatment methods include contacting the produced water with one or more reducing agents and one or more metals, wherein said treatment may result in a reduction of the viscosity of said produced water and/or the degradation of polymers which are contained therein.

Abstract: An automated produced water treatment system that injects ozone or an ozone-oxygen mixture upstream of produced water separators, with the dose rate changing dynamically as the produced water quality changes, as determined by continuous monitoring of the produced water quality by a plurality of sensors that detect water quality parameters in real time. The system may operate as a “slipstream” injection system, that draws a portion of produced water from the produced water pipeline and injects ozone or an ozone-oxygen mixture back into the pipeline with disrupting or slowing normal operations. Disinfectants or other additives may also be injected. The treatment system may be wholly or partially contained in mobile containers or trailers, for on-the-fly use in existing produced water treatment facilities.

Abstract: Described herein are various methods, systems, and apparatus for reducing and eliminating, microbes, minerals, chemicals and biofilms from contaminated substances. A combination of oxidizing agents and radiation of certain wavelengths forming a synergistic reaction. The synergistic reaction generates EMODs, which are effective in reducing microbial count, unwanted mineral or chemical concentrations and eliminating or blocking biofilm formation, particularly in anaerobic environments. The synergistic reaction produces long lasting EMODs thereby creating a residual effect. This synergistic reaction has a relationship to EMOD creation and has a detrimental effect on microbial contamination (MC), mineral contamination (MINC), chemical contamination (CC), microbial influenced corrosion (MIC) and biofilm creation.
