A method and system for treatment of flow-back and produced water from a hydrocarbon well in which fracturing operations are carried out using a phase separation and creating of positive charge in the water.

An apparatus of creating multi-vibrational, frequency-based, electromagnetic fields, which are independent but may work simultaneously can be used in many applications, especially in industrial applications such as cooling towers and related pipes and plumbing. The apparatus eliminates calcium based hard water deposits and prohibits bacteria build-up in cooling towers. The apparatus also helps reduce soap usage in industrial laundry, reduce salt usage in water softeners, reduce chemical use in pools, inhibit algae growth and increase water clarity. The apparatus restructures calcium carbonate and other mineral deposits to prevent mineral buildup. The apparatus may be formed from a plurality of coil assemblies staggered within a circular pipe or undulated within a flat plate and connected to a power supply. The plurality of coil assemblies may be encased in flexible epoxy coating. As a result of the apparatus, waste water is reduced, water costs is kept low, and water is conserved.

A method and system for lessening an amount of methane released into the atmosphere from of a body of water uses an electronic device having an at least partially submerged transducer which provides a signal that enhances oxygenation with a water moving device such as a centrifugal RFWSS to move at least some of the water at a first range of depths within a first density range with at least some of the water at a second lower range of depths within a second density range to lessen a stratification within the body of water wherein the average density in the first density range is different than the average density in the second density range. The use of the two results in an unexpected synergy and promotes oxygenation of the lower layers, thereby lessening an amount methane that would otherwise be released into the atmosphere.

The present disclosure belongs to the technical field of agricultural high-efficiency water-saving irrigation, and relates to a magnetization control apparatus for preventing clogging of a drip irrigation system irrigator and a control method thereof. The method includes: pumping irrigation water from the water source project through the first water pump, passing through the drip irrigation head control hub, and entering the pool; pumping the irrigation water through the second water pump, flowing through the first copper valve, and entering the magnetized pipe; the irrigation water after treated by the magnetizer returning to the pool through the flow rate monitor and the first valve in turn; when water quality of the irrigation water meets water quality requirements entering the capillary pipes, turning off the second water pump and stopping the cyclic magnetization treatment; the third water pump turning on; pumping the irrigation water after the cyclic magnetization treatment from the pool through the third water pump, and filtering through the mesh filter, entering the branch pipe and the capillary pipes through the second valve again; and the irrigation water flowing from the irrigators for irrigation. The present disclosure effectively solves the clogging problem of the drip irrigation system irrigator, has the advantages of cleanliness and high-efficiency; improves crop yield and quality, has a simple operation mode, and is convenient for users to operate.

A modular versatile physicochemical water treatment system and method are provided for treating various water types. The system features an acceleration chamber module combining a static mixer for hydrodynamic cavitation, an ultrasonic transducer assembly (25-40 kHz) for acoustic cavitation, permanent magnets for a static magnetic field, and a magnetic field generating coil for variable multipole magnetic fields, including square and/or triangular waveforms, controlled by a central control unit. Optional modules include a chemical dosing module (Fe.sup.3+/H.sub.2O.sub.2 or O.sub.3/H.sub.2O.sub.2) and an electrolysis module with automatic polarity reversal. The method involves selectively and coordinately applying these effects, tailored to the water type, to achieve optimal treatment efficiency.
