The present invention relates to a device for the reversible adsorption of carbon dioxide from a gas mixture, comprising at least one adsorbent vessel comprising one or a plurality of gas permeable cartridge vessels of an inert and dimensionally stable material, and each cartridge comprising a suitable polymeric particular adsorbent having a primary amino functionality; to an arrangement including the device, and to a method for adand desorption of carbon dioxide.

An aerobic treatment system includes a plurality of highly porous, high surface area, inert, synthetic, inorganic, or natural material particles, having a specific gravity of less than 1.0 that float on an enclosed aqueous environment whereby plants and/or microbes can be grown thereon and/or animals such as fish can be raised therein. The inert particles trap air bubbles and nutrients for the growth of diverse types of plants, animals, or microbial systems, which enable phyto treatment of an aqueous waterbody with the ability to limit the growth of unwanted plant and algae such as blue-green algae. The above aerobic bio treatment system contains desirably bioremediation media having one or more microorganisms that are able to withstand system shocks while minimizing energy usage associated with aeration. The system can generally be utilized in any aqueous environment such as waste water and/or polluted water in an enclosed area such as a container, tank, pond, lake, or the like.

The present disclosure provides systems and methods for improving production of an aquaculture pond farm. The systems generally include an electrolyzer module to produce hydrogen and oxygen, an ammonia synthesizer operable to receive hydrogen produced by the electrolyzer module, and a diffuser to diffuse oxygen produced by the electrolyzer module in the aquaculture pond farm.

A system is provided that promotes ram ventilation for aquatic animals stored therein. The system includes a horizontally oriented container that maintains fluid flow in one predominant direction with a first end of the horizontally oriented container receiving a first volume of fluid and a second end expelling a second volume of fluid. The second end is provided at an opposite side of the horizontally oriented container than the first end. A slot is provided that extends along a lengthwise direction of the horizontally oriented container between the first and second ends. The slot is positioned along an upper portion of the horizontally oriented container. For example, if the horizontally oriented container is tube-shaped, the slot is provided at an uppermost point on the circumference of a horizontally oriented tube directly across from a point on the tube that contacts an underlying surface such a transom of the fishing vessel.

An actuated aquarium decoration system is placed within an aquarium in order to provide an aesthetic appeal to onlookers of the aquarium. The actuated aquarium decoration system includes an aquarium decoration, an actuation mechanism, and a control system. The aquarium decoration is an object placed into the aquarium to provides a theme or habitat within the aquarium. The actuation mechanism engages an accenting feature of the aquarium decoration in order to provide motion or character to the aquarium decoration. The control system the duration, intensity, and frequency of the accenting feature through managing the output of the actuation mechanism.

An aeration fitting for an aquarium including a hollow outer fitting having an interior channel, a cylindrical back portion, a cylindrical front portion having a threaded outer surface, a tapered cylindrical middle portion, and a frontwardly flared outer lip. A floating ball is disposed within the interior channel of the outer fitting. A hollow inner fitting has an inner channel, a cylindrical posterior portion, a cylindrical anterior portion having a threaded inner surface, a tapered cylindrical central portion, and a frontwardly flared inner lip. A spring is disposed within the inner channel of the inner fitting. Each of the back portion of the outer fitting and the posterior portion of the inner fitting is connectable to an air hose, and the threaded outer surface of the front portion is selectively engageable with the threaded inner surface of the anterior portion within an aperture in a wall of an aquarium.

Bio-filter unit (1) intended for a fish farming system, said bio-filter unit (1) comprising a container (2) with a filter media (3) and an inner architecture, said inner architecture comprising at least one vertical tube (5) having an open input end (6) and an open output end (7), wherein the bio-filter unit (1) is connected to a pump (8) enabling pumping liquid and filter media (3) from a bottom (9) of the container (2) against a top (10) of the container (2) through said at least one vertical tube (5), wherein an upper plate (15) is arranged inclined downwards from and around the open output end (7) of the at least one vertical tube (5) and ends at a distance from a wall (13) of the container, wherein the upper plate (15) Is perforated and wherein a regeneration water outflow (16) is arranged under the upper plate (15).

The invention relates to a diffusor for adding of gases into water, said diffusor comprising a perforated tube (1) and at least one supply tube (2), said the at least one supply tube (2) is at one end coupled to a source for supplying gas and at the other end in fluid communication with the perforated tube (1), the gas is supplied to the perforated tube (1) through at least one inner supply tube (4; 5; 15) extending from the supply tube (2) to the perforated tube (1). The invention is distinctive in that at the least one inner supply tube (4; 5; 15) is a non-perforating tube and has at least one outlet (4a, 5a, 15a) situated at a free end of the at least one inner supply tube (4, 5, 15), said gas is adapted to be distributed into the perforated tube (1) through the at least one outlet (4a, 5a, 15a).

A photobioreactor device for growing photosynthetic organisms, organisms that feed on photosynthetic organisms and hydroponics is disclosed. The device may include a lighting system integrated around the circumference of the device. In embodiments, a cap configured to seal the container has ports configured to permit passage of fluid out of or into a container without removing the cap. In some embodiments, organisms are grown in a disposable bag secured between the cap and the container.

A system and method of sustainable aquaponics that vertically integrates unique aquaponic system designs with alternative aquaculture fish feed sources, fingerling production methods, alternative aquaculture/farmed fish grow out models, and green energy sources that yield organic produce in the form of fruits and vegetables. A raceway system serves as the hub for grow-out throughout the warm and cold months. During the summer months, fish can be spawned and fed for steady growth, while during the winter months, the fish continue to grow at slower quite acceptable growth rates. Plants like legal (licensed) cannabis for medical use can be grown in plant areas near the raceways with very high yields. The system may also be used to reclaim gray water using the biology of the system to purify it for agricultural use.
