An eductor includes an adjustable air inductor assembly connected to a source of outside air or other fluid. As liquid flows through a constricted orifice of the eductor, the venturi effect creates a vacuum or low pressure zone that draws inducting fluid through the inductor assembly and infuses such fluid into the liquid driven or transmitted through the eductor. The fluid inducted liquid is then discharged by the eductor into a body or contained volume of water. Improved aeration and fluid flow control, as well as reduced algae growth are achieved without extraneous mechanical equipment. Increased turbulent liquid flow is produced, for example, to more effectively clean dirt and debris from water recirculating swimming pools, fish tanks and similar environments.

This disclosure pertains to modular, moveable light weight structures, i.e., grow towers, including supporting tubing and pumps, used for a hybrid aeroponic and aquaponic growth method of plants and aquaponic growth of animals such as fish wherein the each of the plants and animals are balanced in quantity and produce nutrients that support the growth of the other, i.e., plants and animals. The disclosure also includes an array of sensors, software utilizing artificial intelligence and a CPU for monitoring, controlling and facilitating the growth. The structure and methods utilize and maintain a substantially equilibrium growing conditions requiring minimum intervention. The structure and method also utilizes monitoring of multiple growth variables with systems and CPU programing to adjust and maintain equilibrium conditions.

A system for transferring marine life within an aquaculture facility including a plurality of segregated storage facilities each containing water for marine life, maintained within a predetermined temperature range and supported at independent ground levels. The storage facilities are successively disposed and structured to contain marine life at different stages of growth. A transfer assembly includes a path of fluid flow interconnecting successive ones of said plurality of storage facilities in fluid communication with one another, wherein at least a majority of a length of said path of fluid flow is disposed beneath the independent ground levels at a predetermined depth, which is sufficient to facilitate maintenance of the path of fluid flow within the predetermined temperature range, via geothermal cooling. The transfer assembly may also connect a holding facility, which may be dimensioned and structured to transfer mature marine life, possibly on an on-demand basis, to the harvesting facility.

A device (1) for dissolving a gas (G) in water (W) is provided, and includes a housing (100) configured to be submerged into the water (W) with the housing (100) having at least one water inlet (101), a gas inlet (102) and at least one water outlet (103) for discharging gas enriched water out of the housing (100), a pump (5) in fluid communication with the at least one water inlet (10) for sucking water (W) from a surrounding of the housing (100), the pump configured to generate a main water stream (S′), and means for injecting the gas (G) supplied via the gas inlet (102) into the main water stream (S′). The device (1) includes a probe (6) configured to measure a concentration of the gas dissolved in water, and the probe (6) is arranged in the housing (100) of the device (1).

A net cage for farming of marine organisms is described, where the net cage is comprised of a main chamber to hold the marine organisms and where the net cage has further water chambers to treat the water before it is circulated back to the main chamber.

The present invention is a new process for preserving the water of an aquatic body as a supplying source for different human activities such as recreation and amusement, food and ornamentation, by the development of a aquatic space formed by a Open water Lake, a Spa Lake, and a Water Depuration Lake that preserves the water mass by biotransformation and mineralization that allow reducing the concentration of carbon, nitrogen and phosphorous, generating clean and transparent water without the use of large amounts of chemicals and complex filtrate systems.

Provided is a liquid supply apparatus which is capable of directly taking in a liquid from a flow channel and appropriately mixing a gas into the liquid when generating-nanobubbles in the liquid using an ultrafine bubble generating apparatus. The liquid supply apparatus comprises a flow channel for a liquid supplied from a liquid supply source and an ultrafine bubble generating apparatus for generating nanobubbles in the liquid. The ultrafine bubble generating apparatus is provided with: a liquid ejector for ejecting the liquid taken in from the flow channel; a gas mixer for pressurizing and mixing a gas into the liquid ejected from the liquid ejector; and a nanobubble-generating nozzle for generating nanobubbles in the liquid by passing the liquid with intermixed gas therethrough. The pressure of the liquid in the flow channel flowing into the liquid ejector from the upstream-side of the liquid ejector is a positive pressure and, between the liquid ejector and the-nanobubble-generating nozzle, the gas mixer pressurizes and mixes the gas into the liquid, which is flowing in a pressurized state toward the nanobubble-generating nozzle.

A solar-powered aeration device for sludge turnover and planting includes a grow bed fixed on a floating body and floats on water. A bottom of the floating body is fixedly connected with an inner pipe; an outer pipe is sleeved outside the inner pipe. The outer pipe is nested in an air chamber; a bottom of the air chamber communicates and is fixedly connected with a water inlet pipe; the water inlet pipe laterally communicates with a suction tube. An aeration ring is fixedly arranged at a bottom of the outer pipe, and the aeration tube has an air outlet pipe in communication with the outside. A movable foot is rotationally provided at a tail end of the suction tube, and the movable foot adapts to surface fluctuations to swing in a range limited by an angle limiter.
