A system and method of injecting a gas enriched and/or emulsified first liquid into a second liquid is disclosed. The injection can cause generation of a high density of bubbles having a mean diameter of a selected size. The mean diameter of the bubbles can be selected and varied based on the characteristics of the injection system.

A method of operating a variable speed pump in an aquaculture system including a culture tank that houses aquatic life. The method includes monitoring a dissolved oxygen level in the culture tank, determining a dissolved oxygen threshold based on current respiration requirements of the aquatic life in the culture tank, and comparing the dissolved oxygen level to the dissolved oxygen threshold. When the dissolved oxygen level is below the dissolved oxygen threshold, the method further includes increasing a speed of the variable speed pump until a flow rate through the culture tank that maintains the dissolved oxygen level at or above the dissolved oxygen threshold is reached. The method also includes updating the dissolved oxygen threshold based on new respiration requirements of the aquatic life as the aquatic life matures through its growth cycle.

A method and device (10) for producing and dispensing oxygenated water. A mixing unit (30) has an inlet for supplying water to the mixing unit, and an inlet for supplying oxygen to the unit. Separate control valves or devices are installed in the respective flow paths by which water and oxygen are directed to their respective inlets so to separately control the rate at which water and oxygen are supplied to it. The mixing unit includes an element (39) for dissolving oxygen supplied to the mixing unit into the water also supplied thereto, the mixing unit controlling the level of oxygen dissolution into the water. A dispenser (46) is connected to an outlet (42) of the mixing unit for dispensing oxygenated water into a container (G) for subsequent consumption. It is desirable to consume the oxygenated water as soon as possible to realize the full benefits of the oxygen dissolved in water.

Embodiments of the invention provide a method of operating a pump in an aquaculture system including a water tank that houses aquatic life. The method includes monitoring a dissolved oxygen level in the culture tank, determining a flow rate threshold based on the dissolved oxygen level, and changing a speed of the pump to maintain a current flow rate through the culture tank above the flow rate threshold.

This invention relates to a method and an apparatus for energizing and aerating fluids, comprising the step of subjecting a starting liquid to a process in order to produce an energized liquid the molecules of which are clustered and can have a specific wavelength, magnetic field, and hydrating properties.

Water charging machine wherein the water being treated is moved through a geometric series of spheres, creating a series of waterfall-like events within this invention. Oxygen may be introduced into the stream of water either upstream of this invention, or into the inside of this invention, or both, to provide a long shelf life incorporation of the gaseous oxygen into the water through vortex and waterfall actions. The water and oxygen is also exposed to a negative or positive magnetic field and a piezoelectric field as it travels through this invention, to provide a substantial Zeta potential.
